What Is Mistral AI on AI Assistant Bot and How Do You Use It?

Updated

Mistral AI on AI Assistant Bot is a set of selectable Mistral and Mixtral models inside a multi-model chat interface. You open the site, pick a Mistral-family model from the model list, and start chatting in the same window. The page lists Mistral Large, Mistral Small, Mistral Medium, Mixtral 8x22b, Mistral Nemo, Codestral, Devstral, Magistral, Pixtral, and Ministral variants, so the practical task is choosing the right one for general chat, coding, or image input rather than installing anything.

Mistral models available on the site

The site's model list groups several families. The Mistral-related entries shown are:

Model Likely best for
Ministral 8b / 14b Lightweight general chat
Mistral Nemo Everyday conversation
Mixtral 8x22b Broader general reasoning
Mistral Small / Medium / Large-2411 / Large 3 General chat at increasing capability
Mistral Saba General chat
Codestral Code generation and editing
Devstral 2 Developer-oriented coding tasks
Magistral Small / Medium Reasoning-style prompts
Pixtral 12b-2409 / Pixtral Large-2411 Prompts that include images

The list also includes non-Mistral models (Llama, DeepSeek, Qwen, GPT OSS, Phi, Kimi, Minimax), which matters when you compare results.

How to start a Mistral chat

  1. Open aiassistantbot.pages.dev in a browser.
  2. Find the model selector in the chat interface. The page shows a model list and a "Talk to your own assistant!" prompt area.
  3. Select a Mistral-family model, for example Mistral Large-2411 for general chat or Codestral for code.
  4. Type your message in the input field and send it.
  5. Check the reply header or model label to confirm the selected model answered.

Expected result: a response generated by the chosen Mistral model in the same chat window. The interface also shows Save Chat, download, and Import Chat controls, so you can keep a session and reload it later.

Using image input

If your prompt includes an image, choose a Pixtral model (Pixtral 12b-2409 or Pixtral Large-2411). The interface includes an attach/upload control, and the model list marks image generation separately with "Generate Images." Do not assume a text-only Mistral model will read an attached image.

Choosing between Mistral models

Use the same three questions for every model on the site:

  • Task type: general chat → Mistral Small/Medium/Large or Mixtral; code → Codestral or Devstral 2; image input → Pixtral.
  • Speed vs. depth: smaller models (Ministral 8b, Mistral Small) are the lighter options; larger ones (Mistral Large 3, Mixtral 8x22b) suit longer or harder prompts.
  • Consistency: if a reply looks weak, switch to another Mistral model and resend the same prompt before concluding the task is impossible.

The site describes itself as "Chat with 30+ AI Models for free," but the provided page evidence does not list prices, login requirements, or usage caps. Treat availability and limits as things to confirm on the page itself rather than assuming unlimited free access.

Common problems and fixes

  • Wrong model answered. Reopen the model selector and confirm the highlighted model before sending; the list is long and easy to mis-click.
  • No response. Try a different Mistral model, then a non-Mistral model, to see whether the issue is the specific model or the session.
  • Image ignored. Switch to a Pixtral model and re-attach the file.
  • Lost conversation. Use Save Chat or download before closing the tab; Import Chat restores a saved session.
  • Weak code output. Move from a general Mistral model to Codestral or Devstral 2 and include the language, input, and expected output in the prompt.

The main decision is simple: pick the Mistral variant that matches your task, verify the selection before sending, and switch models rather than repeating a failing prompt.
