What is CoreWeave Forge?

CoreWeave Forge is the part of the CoreWeave platform aimed at teams that build, evaluate, and run AI models and agents. It groups together tools for experiment tracking, LLM and agent evaluation, notebooks, model and dataset registries, and serverless options for serving, fine-tuning, and sandboxed execution.

From the documentation index, Forge covers:

  • Weights & Biases (W&B Models and W&B Weave) — experiment tracking, hyperparameter sweeps, artifacts, reports, and automations; Weave handles LLM and agent evaluation.
  • ARIA — an AI research agent that analyzes experiments, explains results, and builds visualizations and reports (listed as Preview).
  • Agent Lens — observability and improvement for agents.
  • Notebooks — reactive Python notebooks for exploring data, prototyping model workflows, and analyzing runs and artifacts.
  • Registry — a versioned hub for models and datasets with lineage and deployment handoff.
  • Serverless services — Post-Training (Serverless RL and SFT), Serverless Inference (OpenAI-compatible API integrated with Weave), and Serverless Sandbox (on-demand isolated compute you create and discard from Python).

Forge sits alongside the rest of the CoreWeave stack: infrastructure (instances, capacity, regions, billing, policies), Mission Control, infrastructure control (CKS plus storage and networking), observability (Grafana dashboards, logs, metrics, telemetry, alerts), and access control.

Practical takeaway: Forge is most relevant if your work is model development and evaluation rather than raw cluster operations. A typical path is to prototype in Notebooks, track runs and artifacts in W&B, evaluate an LLM or agent with Weave, version the result in Registry, then hand it off to Serverless Inference or Post-Training. If your main need is managing Kubernetes clusters or hardware, the Infrastructure and Infra Control sections are the better starting points.

Next step: Open the Forge section of the CoreWeave documentation and read the Weights & Biases and Serverless Inference pages first, since together they show the most common develop-to-deploy workflow.

How do I get started with CoreWeave Forge?

Start with the Forge section of the documentation index, then pick the specific Forge product that matches your task — the docs are organized by capability rather than as a single linear tutorial.

What the Forge section covers

  • Develop and evaluate — experiment tracking, evaluation, and improvement of agents and LLM applications, plus prototyping in notebooks and model lifecycle management.
  • Weights & Biases — W&B Models for experiment tracking, hyperparameter sweeps, artifacts, reports, and automations, with W&B Weave for LLM and agent evaluation.
  • ARIA — an AI research agent that analyzes experiments, explains results, and builds visualizations and reports (listed as preview).
  • Agent Lens — observability and improvement for agents.
  • Notebooks — reactive Python notebooks for exploring data, prototyping model workflows, and analyzing runs and artifacts.
  • Registry — a versioned hub for models and datasets with lineage and deployment handoff.
  • Serverless services — Post-Training, Serverless Inference, and Serverless Sandbox, for serving, fine-tuning, and running models without managing infrastructure.

A practical first path

If you are new, the lowest-friction entry point is Notebooks: you get a Python environment for exploring data and prototyping without committing to a training or serving setup. If your goal is measuring model or agent quality, start with Weights & Biases instead, since tracking and evaluation are the foundation the other Forge tools build on. If you already have a model and want to expose it, go straight to Serverless Inference.

Choosing between them

Your immediate goal Start with
Explore data, prototype workflows Notebooks
Track experiments, compare runs W&B Models
Evaluate an LLM app or agent W&B Weave or Agent Lens
Store and version models/datasets Registry
Serve or fine-tune a model Serverless Inference / Post-Training

Note that Forge sits alongside separate infrastructure documentation — Platform, Mission Control, Infra Control (including CoreWeave Kubernetes Service), Observability, Workloads, and Access Control. You will likely need the Access Control pages for accounts and authentication before any Forge tool will run against your environment.

Your next step: open the Forge index page, choose the product matching the table above, and follow its own getting-started page rather than the top-level index, which is a map rather than a walkthrough.

What tools does Forge provide for tracking and evaluating machine learning experiments?

Forge's experiment tracking and evaluation tools are centered on Weights & Biases, with ARIA and Agent Lens adding analysis and agent observability on top.

Core tracking and evaluation

  • W&B Models — experiment tracking, hyperparameter sweeps, artifacts, reports, and automations.
  • W&B Weave — evaluation and monitoring for LLM and agent applications, positioned alongside Models.
  • ARIA — an AI research agent that analyzes experiments, explains results, and builds visualizations and reports (listed as preview).
  • Agent Lens — observability and improvement for agents.
  • Notebooks — reactive Python notebooks for exploring data, prototyping model workflows, and analyzing runs and artifacts.
  • Registry — a versioned hub for models and datasets with lineage and deployment handoff.

How the pieces differ

Need Likely fit
Classic training runs, sweeps, artifacts, reports W&B Models
LLM/agent evaluation and monitoring W&B Weave
Agent-specific observability Agent Lens
Explaining results and generating visualizations ARIA (preview)
Interactive exploration of runs and artifacts Notebooks
Versioning models/datasets with lineage Registry

A practical next step

If you are already logging runs with W&B Models, the fastest way to add evaluation is to route your LLM or agent traces through Weave and use Agent Lens for agent behavior; keep Notebooks for exploratory analysis and Registry for promoting evaluated artifacts. If you are starting fresh, begin with W&B Models for training metrics and sweeps, then layer in Weave when you begin evaluating prompts or agents.

One caveat: ARIA and Agent Lens are described as preview or newer additions, so verify current availability before making them a dependency in a production workflow. Start from the Forge section of CoreWeave Docs to confirm which of these are generally available.

How does Weave help with evaluating LLM applications and agents?

Weave is CoreWeave's tool for evaluating LLM applications and agents, positioned alongside W&B Models for experiment tracking. According to the CoreWeave documentation, W&B Weave sits next to W&B Models and is intended specifically for "LLM and agent evaluation," while models themselves are managed across their lifecycle under Forge's develop-and-evaluate section. That tells you the intended division of labor: Weave is the evaluation layer, not the training or serving layer.

What that means in practice

If you are building an agent or an LLM application, evaluation is usually the hardest part to get right. You need to know whether a change to a prompt, a retrieval step, or a tool-calling loop actually improved things. Weave's role, as described, is to give you a place to run and compare those evaluations rather than eyeballing outputs. The docs also mention Serverless Inference is "integrated with Weave," which suggests you can evaluate against served open-source foundation models without wiring up your own inference stack.

A concrete scenario: you have a support agent that calls two tools. You change the system prompt and want to know if resolution quality improved without regressions on edge cases. An evaluation tool like Weave is where you would define those cases, run them against both versions, and compare results — rather than shipping and hoping.

Where it fits among the other tools

Tool Primary job
W&B Models Experiment tracking, sweeps, artifacts, reports
W&B Weave LLM and agent evaluation
Agent Lens Agent observability and improvement (marked Preview)
ARIA AI research agent that analyzes experiments and builds reports (marked Preview)
Registry Versioned models and datasets with lineage

Note that Agent Lens and ARIA are both labeled Preview in the page evidence, so treat them as less settled than Weave itself.

Next step

Decide based on what you lack. If you can already run evaluations but cannot see why an agent failed in production, look at Agent Lens. If your problem is comparing candidate prompts or models systematically, Weave is the direct fit. Start from the Forge section of the documentation to see how Weave connects to Models and Serverless Inference.

What options does Forge offer for serving and fine-tuning models without managing infrastructure?

Forge covers this through its Serverless services group, which is explicitly framed as serving, fine-tuning, and running models on CoreWeave infrastructure without you managing it. Two entries sit under that heading:

  • Serverless Inference — open-source foundation models exposed through an OpenAI-compatible API, integrated with Weave. The OpenAI-compatible interface matters practically: code already written against the OpenAI client libraries can often be repointed at this endpoint with minimal changes, which lowers migration effort for teams prototyping or comparing models.
  • Serverless Sandbox — on-demand, isolated compute environments created and discarded from Python. This suits short-lived jobs (testing a fine-tune, running an evaluation, reproducing a result) where you do not want a persistent cluster.

Fine-tuning specifically is addressed under Post-Training, described as post-training and fine-tuning LLMs with Serverless RL and SFT, plus distilling specialized models from real application traffic. So the "no infrastructure management" path splits by intent: inference for serving, post-training for adapting models, sandbox for throwaway compute.

A useful next step: decide which of the three you actually need before reading further. If you only need to call an existing open-source model, start with Serverless Inference. If you have your own data and want a model tailored to it, start with Post-Training. If you are still experimenting, the Sandbox is the cheapest place to be wrong.

Note that Forge also includes adjacent tooling that is not itself serverless: Weights & Biases for experiment tracking, sweeps, artifacts and reports; Weave for LLM and agent evaluation; ARIA, an AI research agent that analyzes experiments and builds visualizations; Agent Lens for agent observability; Notebooks for prototyping; and a Registry for versioned models and datasets with lineage and deployment handoff. These are the layers you would typically pair with the serverless endpoints rather than replacements for them. ARIA is marked as a preview, so treat it as unproven for production workflows.

For the authoritative, current list and any limits, see CoreWeave Docs.

How can I use CoreWeave Forge for developing and evaluating AI agents?

CoreWeave Forge is the part of the CoreWeave documentation aimed at developing and evaluating AI agents and LLM applications. Its building blocks map to the agent-development loop: track experiments, evaluate and improve agents, prototype in notebooks, and manage models across their lifecycle.

What each component is for

  • Weights & Biases (W&B Models) — experiment tracking, hyperparameter sweeps, artifacts, reports, and automations. This is where you record runs and compare configurations.
  • W&B Weave — LLM and agent evaluation, sitting alongside W&B Models. Use it to score agent outputs and iterate on prompts or workflows.
  • ARIA — an AI research agent that analyzes experiments, explains results, and builds visualizations and reports. Marked as a preview.
  • Agent Lens — intelligent agent observability and improvement.
  • Notebooks — reactive Python notebooks for exploring data, prototyping model workflows, and analyzing runs and artifacts.
  • Registry — a versioned hub for models and datasets with lineage and deployment handoff.

A practical way to use it

A common pattern is to prototype the agent in Notebooks, log each run to W&B Models, evaluate outputs with Weave, and register the winning model or dataset version in Registry before handing it off to a serving path. Agent Lens and ARIA add observability and automated analysis on top.

Choosing between them

Need Component
Compare runs, sweeps, artifacts W&B Models
Score and improve agent/LLM outputs W&B Weave
Understand why an agent behaves as it does Agent Lens
Automated analysis and reporting ARIA (preview)
Interactive prototyping and analysis Notebooks
Versioning and deployment handoff Registry

For serving the finished agent, the same docs point to Serverless Inference with an OpenAI-compatible API integrated with Weave, plus Serverless Sandbox for isolated, disposable compute environments created from Python.

A useful next step: start with one Notebooks prototype, log it to W&B Models, and add a Weave evaluation before investing in sweeps or registry workflows. Confirm current capabilities, preview status, and availability in the official CoreWeave documentation at CoreWeave Docs.

How to Use Ahrefs for Your First SEO Audit: A Step-by-Step Tutorial

If you're new to Ahrefs and want to run your first SEO audit, the fastest path is: open Site Explorer, enter your target URL, review the Overview for a health snapshot, then dig into Organic Keywords, Top Pages, and Site Audit to find specific problems. From there, build a short prioritized to-do list instead of trying to fix everything at once.

This tutorial walks through that workflow using a realistic starting scenario, explains what the numbers mean, and shows how to turn findings into actions.

Before You Start: Pick a Narrow Scope

A common beginner mistake is auditing an entire large website on day one. The reports become overwhelming, and you can't tell which issues matter.

Instead, choose one of these starting points:

  • A single important page (your homepage or a key product/service page)
  • A small site (under ~50 pages, e.g., a personal blog or small business site)
  • One section of a bigger site (e.g., /blog/)

For this tutorial, assume you're auditing a small business site with about 30 pages. The same steps scale up later.

You'll need an Ahrefs account to follow along. Ahrefs offers paid plans, and pricing and feature limits change over time, so check the current Pricing page for what's included in each tier before committing.

Step 1: Enter Your Target in Site Explorer

Site Explorer is Ahrefs' core tool for analyzing any website or URL.

  1. Open Site Explorer from the top navigation.
  2. In the search box, paste your domain (e.g., example.com).
  3. Choose the Exact URL or Domain mode depending on scope. For a full-site view, use Domain or Prefix; for a single page, use Exact URL.
  4. Press Enter.

You'll land on the Overview report. Don't try to absorb everything — focus on four numbers first.

Reading the Overview Snapshot

Metric What it tells you How to use it
Ahrefs Rank (AR) Relative strength of the site's backlink profile vs. others in the database Useful for comparing against competitors, not as a standalone goal
Organic traffic Estimated monthly visits from search A rough trend indicator, not exact analytics
Organic keywords Estimated number of keywords the site ranks for Shows breadth of visibility
Backlinks / Referring domains Total links and unique sites linking to you Referring domains matter more than raw backlink count

Important caveat: Ahrefs' traffic and keyword numbers are estimates based on its own data. They won't match Google Search Console or your analytics exactly. Treat them as directional, not absolute.

Step 2: See What You Already Rank For

Go to Organic Keywords in the left sidebar. This shows queries where your site appears in search results.

Sort by Traffic (descending) to see which pages bring the most estimated visitors. Then look for:

  • Keywords ranking in positions 4–15 — these are often the easiest wins. A small content or on-page improvement can push them onto page one.
  • Keywords with high volume but low position — potential opportunities if the topic is relevant.
  • Irrelevant keywords — if you rank for something off-topic, it may signal thin or mismatched content.

Write down 5–10 of the position 4–15 keywords. These become your first optimization targets.

Step 3: Find Your Best and Weakest Pages

Open Top Pages. This ranks your URLs by estimated organic traffic.

Look for two things:

  1. Your top performers — understand what topics and formats work. Can you create more content like this?
  2. Pages with traffic but poor rankings — these may need on-page fixes (title, headings, internal links).

If a page gets zero traffic and targets a topic you care about, it's a candidate for a rewrite or consolidation.

Step 4: Run a Technical Site Audit

Now move to Site Audit. This crawls your site and flags technical and on-page issues.

  1. Click Site Audit → New project.
  2. Enter your domain and set crawl settings (default is usually fine for a small site).
  3. Start the crawl and wait for it to finish.

Once complete, you'll see a Health Score and a list of issues grouped by category.

Which Issues to Fix First

Not all issues are equal. Prioritize in this order:

Priority Issue type Why it matters
1 Broken links (404s) Bad for users and crawl efficiency
2 Pages blocked from indexing They can't rank at all
3 Missing or duplicate title tags Directly affects click-through and relevance
4 Slow-loading pages Affects experience and rankings
5 Thin content Low value to users and search engines

Ignore low-impact warnings (like minor meta description length) until the big items are handled.

Step 5: Turn Findings Into a To-Do List

You now have raw data. Convert it into a short, actionable list. Example:

  1. Fix 3 broken links found in Site Audit.
  2. Rewrite title tags on 5 pages with duplicate titles.
  3. Improve 4 pages ranking in positions 6–12 by adding missing subtopics and internal links.
  4. Remove or update 2 thin pages with no traffic.

Keep the list to 5–10 items max for your first audit. Finishing a short list beats starting a long one.

Common Beginner Mistakes

  • Chasing every red flag. Site Audit flags many minor issues. Fix what affects rankings and users first.
  • Trusting estimates as exact numbers. Ahrefs data is modeled, not measured from your analytics.
  • Auditing a huge site too early. Start small to learn the interface.
  • Ignoring search intent. A page can be technically perfect but still fail if it doesn't match what searchers want.
  • Forgetting to re-crawl. After fixes, run Site Audit again to confirm improvements.

Where to Go Next

Once your first audit is done:

  • Compare with competitors using Site Explorer's Competing Domains and Content Gap reports.
  • Track keyword rankings over time with Rank Tracker.
  • Explore backlink opportunities in the Backlinks and Link Intersect reports.
  • Set up recurring Site Audit crawls so new issues surface automatically.

Your first audit isn't about perfection — it's about building a repeatable habit: enter a target, read the key reports, pick the highest-impact fixes, and act. Do that once a month and your site's health compounds.

What Is CoreWeave Documentation (docs.coreweave.com)?

CoreWeave Documentation is the official documentation site for CoreWeave, a cloud platform for deploying, managing, and observing workloads. It is aimed at users who run workloads on CoreWeave infrastructure, and it organizes its content into two main areas: Infrastructure and Forge. If you need to understand how CoreWeave is structured, find setup instructions, or learn how to operate workloads on the platform, this is the reference site to start from.

What the documentation covers

The site is divided into a documentation index with two top-level sections.

Infrastructure

This section covers the platform layer — the resources your workloads run on and the controls around them:

  • Platform — getting started, choosing instances and capacity, regions and Availability Zones, billing, and policies.
  • Mission Control — the Mission Control Agent and the Mission Control MCP server, used for investigating your environment and making supported changes.
  • Infra Control — CoreWeave Kubernetes Service (CKS) plus the storage and networking products your clusters use.
  • Observability — Grafana dashboards, logs, metrics, telemetry, and alerts for monitoring fleet hardware and workloads.
  • Workloads — SUNK for Slurm on Kubernetes, CoreWeave Inference for serving models, and CoreWeave Sandbox for isolated environments.
  • Access Control — accounts and authentication, IAM access policies, automated user provisioning, and trust and compliance.

Forge

Forge is the developer-facing area for building and evaluating AI work:

  • Weights & Biases — W&B Models for experiment tracking, hyperparameter sweeps, artifacts, reports, and automations, with W&B Weave alongside for LLM and agent evaluation.
  • ARIA — an AI research agent that analyzes experiments, explains results, and builds visualizations and reports. Marked as Preview.
  • Agent Lens — intelligent agent observability and improvement.
  • Notebooks — reactive Python notebooks for exploring data, prototyping model workflows, and analyzing runs and artifacts.
  • Registry — a versioned hub for models and datasets with lineage and deployment handoff.
  • Serverless services — serving, fine-tuning, and running models without managing infrastructure:
    • Post-Training — post-train and fine-tune LLMs with Serverless RL and SFT, and distill specialized models from real application traffic.
    • Serverless Inference — open-source foundation models through an OpenAI-compatible API, integrated with Weave.
    • Serverless Sandbox — on-demand, isolated compute environments you create and discard from Python.

Who it is for

The documentation is written for people who deploy, manage, and observe workloads on CoreWeave. That includes:

  • Platform and infrastructure engineers setting up clusters, storage, and networking.
  • ML and AI practitioners running experiments, fine-tuning, or serving models.
  • Operations staff who need observability, access control, and policy information.

How to use it

Start with the Documentation Index to pick the area that matches your task. If you are new to the platform, begin with Platform under Infrastructure to get started and understand instances, capacity, and regions. If your work is model- and experiment-focused, go directly to Forge. Each section is self-contained, so you can move between Infrastructure and Forge depending on whether you are managing the environment or building on top of it.

One note on scope: the documentation describes capabilities and workflows, but the page evidence does not include pricing details or login requirements. Treat those as things to confirm separately rather than assuming free or unrestricted access.

What Observability and Agent Tooling Does CoreWeave Documentation Cover?

CoreWeave's documentation covers two related but distinct tooling areas: Observability for monitoring infrastructure and workloads (Grafana dashboards, logs, metrics, telemetry, alerts), and agent tooling split across Mission Control (an agent plus MCP server for investigating and changing your environment), Agent Lens (agent observability and improvement), and ARIA (an AI research agent for analyzing experiments and building reports). If you need to watch cluster health, use Observability and Mission Control. If you need to build or improve AI agents and models, look at Forge, Agent Lens, and ARIA.

Observability: monitoring fleet hardware and workloads

The Observability section is described as covering "Grafana dashboards, logs, metrics, telemetry, and alerts for monitoring fleet hardware and workloads." In practice, this is the layer you reach for when you want to answer questions like is a node degraded, is a workload saturating its allocation, or did something change in the last hour?

The documented components break down as:

Component What it gives you
Grafana dashboards Visual views of your environment and workloads
Logs Recorded output for investigation
Metrics Numeric time-series data on hardware and workloads
Telemetry Ongoing signal collection from the fleet
Alerts Notifications when conditions you care about are met

A concrete use case: you notice inference latency rising on a deployment. You open the relevant Grafana dashboard, confirm the metric trend, cross-check logs for errors, and set or adjust an alert so the next occurrence pages you instead of being discovered after the fact.

Mission Control: investigating and making supported changes

Mission Control is documented as "Mission Control Agent and the Mission Control MCP server for investigating your environment and making supported changes." Two things matter here:

  • Mission Control Agent — the agent interface for investigating your environment.
  • Mission Control MCP server — an MCP (Model Context Protocol) server, which lets MCP-compatible clients interact with Mission Control programmatically.

The phrase "making supported changes" is the key constraint: Mission Control is not described as an unrestricted control plane. Treat it as a way to investigate and apply changes that the documentation explicitly supports, and verify scope before relying on it for anything destructive.

Agent and model tooling under Forge

Forge is the section for developing and evaluating: "Track experiments, evaluate and improve agents and LLM applications, prototype in notebooks, and manage models across their lifecycle." Three named tools are relevant to agent observability and improvement.

Agent Lens

Documented as "Intelligent agent observability and improvement." This is the piece to look at when your question is specifically about how an agent is behaving — as opposed to how the underlying infrastructure is behaving. Observability tells you whether the GPU fleet is healthy; Agent Lens is aimed at the agent layer itself.

ARIA

ARIA is described as an "AI research agent that analyzes experiments, explains results, and builds visualizations and reports," and is marked Preview. The Preview label is worth noting: expect the interface and behavior to be less settled than generally available tooling, and check the docs for current limitations before building a workflow around it.

A fitting scenario: you've run a set of training or evaluation experiments and want a summary of what changed and why. ARIA is the documented tool for analyzing those experiments, explaining results, and producing visualizations and reports.

Weights & Biases alongside Forge

Forge also documents Weights & Biases: "W&B Models for experiment tracking, hyperparameter sweeps, artifacts, reports, and automations, with W&B Weave alongside for LLM and agent evaluation." If your need is experiment tracking and sweeps, W&B Models is the documented path; if your need is LLM and agent evaluation specifically, that's W&B Weave.

Choosing between them

Your question Where to look
Is my fleet hardware or workload healthy? Observability (Grafana, logs, metrics, telemetry, alerts)
I want to investigate my environment and apply supported changes Mission Control (Agent and MCP server)
How is my agent actually behaving? Agent Lens
Analyze experiments, explain results, build reports ARIA (Preview)
Track experiments, sweeps, artifacts W&B Models
Evaluate LLM and agent applications W&B Weave

Where to start

The documentation index groups these under two top-level areas: Infrastructure (Platform, Mission Control, Infra Control, Observability, Workloads, Access Control) and Forge (develop and evaluate). If your goal is monitoring and troubleshooting, start in Infrastructure → Observability, then read Mission Control if you need agent-assisted investigation. If your goal is building or improving agents and models, start in Forge and read Agent Lens, ARIA, and the Weights & Biases entries together, since they cover overlapping parts of the experiment-and-evaluation lifecycle.

What Workloads and Services Can You Run on CoreWeave?

CoreWeave's documentation describes a platform for deploying, managing, and observing workloads, organized into two main areas: Infrastructure (the platform layer) and Forge (the development and evaluation layer). If you want to run model training, inference, or isolated compute jobs, the docs point you to specific products depending on whether you need full cluster control, a managed serving endpoint, or a throwaway sandbox.

Workload products

The Workloads section of the documentation lists three named products:

Product What it is for
SUNK for Slurm on Kubernetes Running Slurm-style workloads on Kubernetes
CoreWeave Inference Serving models
CoreWeave Sandbox Isolated environments

These cover the core execution patterns: batch/HPC-style scheduling (SUNK), model serving (Inference), and isolation (Sandbox).

Serverless services

If you don't want to manage infrastructure yourself, the docs describe serverless options:

  • Serverless Inference — open-source foundation models through an OpenAI-compatible API, integrated with Weave.
  • Post-Training — post-train and fine-tune LLMs with Serverless RL and SFT, and distill specialized models from real application traffic.
  • Serverless Sandbox — on-demand, isolated compute environments you create and discard from Python.

The distinction matters: Serverless Inference is for consuming models behind a familiar API, Post-Training is for adapting models to your own data, and Serverless Sandbox is for short-lived isolated execution driven from Python code.

Managing and observing workloads

Two infrastructure products sit alongside the workload layer:

  • Mission Control — an agent and an MCP server for investigating your environment and making supported changes.
  • Infra Control — CoreWeave Kubernetes Service (CKS) plus the storage and networking products your clusters use.

For monitoring, Observability provides Grafana dashboards, logs, metrics, telemetry, and alerts for fleet hardware and workloads. Access Control covers accounts and authentication, IAM access policies, automated user provisioning, and trust and compliance.

In practice these work together: you define who can act (Access Control), run and adjust workloads (Infra Control, Mission Control), and watch what happens (Observability).

Forge: developing and evaluating

Forge is the development and evaluation side of the platform:

  • Weights & Biases — W&B Models for experiment tracking, hyperparameter sweeps, artifacts, reports, and automations, with W&B Weave for LLM and agent evaluation.
  • ARIA — an AI research agent that analyzes experiments, explains results, and builds visualizations and reports (marked Preview).
  • Agent Lens — intelligent agent observability and improvement.
  • Notebooks — reactive Python notebooks for exploring data, prototyping model workflows, and analyzing runs and artifacts.
  • Registry — a versioned hub for models and datasets with lineage and deployment handoff.

Where to start

The documentation index splits into Infrastructure (Platform, Mission Control, Infra Control, Observability, Workloads, Access Control) and Forge (the development and evaluation tools above). If your goal is to run a job, start with Workloads or the serverless services; if your goal is to experiment and track results, start with Forge.

What Is Forge in the CoreWeave Documentation?

Forge is the section of the CoreWeave documentation that covers developing and evaluating AI workloads, rather than running the underlying infrastructure. It is the place to look if you want to track experiments, evaluate and improve agents and LLM applications, prototype in notebooks, or manage models across their lifecycle. If your question is about provisioning GPUs, clusters, storage, or networking, that lives under Infrastructure instead.

What Forge covers

The documentation groups Forge around a single purpose: "Develop and evaluate." Within that, it lists four broad capabilities:

  • Track experiments — record runs, parameters, and results.
  • Evaluate and improve agents and LLM applications — measure quality and iterate.
  • Prototype in notebooks — explore data and model workflows interactively.
  • Manage models across their lifecycle — version, store, and hand off models and datasets.

The tools inside Forge

Tool What it does
Weights & Biases (W&B Models) Experiment tracking, hyperparameter sweeps, artifacts, reports, and automations.
W&B Weave LLM and agent evaluation, alongside W&B Models.
ARIA AI research agent that analyzes experiments, explains results, and builds visualizations and reports. Marked as Preview.
Agent Lens Intelligent agent observability and improvement.
Notebooks Reactive Python notebooks for exploring data, prototyping model workflows, and analyzing runs and artifacts.
Registry Versioned hub for models and datasets with lineage and deployment handoff.

The relationship between these is layered rather than parallel. W&B Models handles the general experiment-tracking layer, and Weave sits alongside it specifically for LLM and agent evaluation. ARIA and Agent Lens build on top of that recorded data — ARIA to interpret experiments and produce visualizations and reports, Agent Lens to observe and improve agents. Notebooks and Registry are the working surfaces: you prototype in notebooks, and you version and hand off what you produce through the registry.

How Serverless services fit in

Forge also lists Serverless services, described as a way to "serve, fine-tune, and run models on CoreWeave infrastructure without managing it." Three are named:

  • Post-Training — post-train and fine-tune LLMs with Serverless RL and SFT, and distill specialized models from real application traffic.
  • Serverless Inference — open-source foundation models through an OpenAI-compatible API, integrated with Weave.
  • Serverless Sandbox — on-demand, isolated compute environments you create and discard from Python.

These sit in Forge because they are part of the model development and evaluation loop rather than the infrastructure layer. Serverless Inference being integrated with Weave is the clearest link: you can serve a model and evaluate it in the same workflow.

Where to start

If you are new to Forge, the order implied by the documentation is:

  1. Notebooks — prototype and explore data or model workflows.
  2. W&B Models and Weave — track experiments and evaluate LLM or agent behavior.
  3. ARIA and Agent Lens — once you have runs recorded, use these to analyze results and improve agents. Note that ARIA is labeled Preview.
  4. Registry — version what you want to keep and hand off for deployment.
  5. Serverless services — serve, fine-tune, or run the model without managing infrastructure.

If you instead need to set up the environment these run on — instances, capacity, regions, billing, or policies — start from the Infrastructure section of the docs. Forge assumes that layer is already in place.

Website Overview

An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality. Page metadata, canonical configuration and social previews work together to provide more consistent search and sharing presentation.

Domain and Registration

Registered in 2019, this domain has about 7 years of history. That suggests continuity, although ownership and purpose may have changed. Transfer-protection status is present, helping reduce the risk of unauthorized domain transfers. The registrar is GoDaddy.com, LLC, a widely used domain service provider. The domain uses the common .com extension, which is not an independent safety signal.

DNS and Email

The lowest TTL is 30 seconds, supporting rapid record changes at the cost of more frequent lookups. Nameservers are provided by Cloudflare, indicating managed DNS hosting. MX records point to the Proofpoint email service. No CNAME was found; the observed records resolve directly to addresses. SPF and DMARC are configured. DKIM status is unknown.

TLS and Certificates

The public key uses EC with 256 bits. The server supplied a complete certificate chain. No organization name is present in the certificate; the available fields are consistent with domain validation.
