Which should you use?

Benchmarks can only tell you so much. The honest answer for any real workload is: send the same prompt to both and read the two answers yourself.

Free.ai's compare tool lets you do that in a single view, and the AI Arena collects community votes on blind responses if you want a broader signal.

FAQ

ChatGPT vs Mistral is a side-by-side comparison of two AI models. ChatGPT is built by OpenAI, and Mistral by Mistral. Send them the same prompt at /chat/compare/ and read both answers side by side.

Not free — ChatGPT and Mistral are premium external models routed through third-party providers, so they require purchased tokens (starting at $5 for 200,000 tokens). Only Free.ai's self-hosted open-source models like Qwen, Mistral, DeepSeek, FLUX, Kokoro, and Whisper are free to use without purchase.

Depends on your workload. Send the same prompt to both at /chat/compare/ and judge the two answers directly — benchmarks can only tell you so much. The AI Arena also collects community votes on blind responses if you want a broader signal.

Yes — ChatGPT and Mistral are premium external models that need purchased tokens. You can create a free Free.ai account and buy tokens starting at $5 for 200K. Our self-hosted open-source models (Qwen, Mistral, DeepSeek, FLUX, Kokoro, Whisper, etc.) are free with an account and work without any purchase.

The compare tool sends the same prompt to ChatGPT and Mistral in parallel and streams both responses side by side. Each panel has its own conversation history, so you can follow up differently on each side.

Yes. Each panel has its own model picker — change ChatGPT or Mistral to any of 370+ models at any time. The conversation history on each side is preserved.

Free.ai bills in tokens, not per-message. A typical chat turn on ChatGPT uses about 3,825 Free.ai tokens per message; on Mistral, about 3,150 Free.ai tokens per message. $5 buys 200,000 tokens and they never expire. Self-hosted open-source models are free up to your daily allowance.

ChatGPT supports 1,047,576 tokens of context; Mistral supports 131,072 tokens. Context window is how much text the model can read in a single conversation before older messages start being trimmed.

Yes. Signed-in users have their compare sessions saved automatically — see the sidebar on /chat/compare/ for past comparisons. Each comparison stores both sides (Model A and Model B) independently so you can revisit exact responses.

Only for external models. ChatGPT runs on OpenAI's servers (premium); your prompt is routed there through our external-model gateway when you use this pair. Self-hosted open-source models like Qwen, Mistral, DeepSeek, FLUX, Kokoro, and Whisper run on Free.ai's own GPUs — nothing leaves our infrastructure.

Yes. Both ChatGPT and Mistral are accessible through the Free.ai API — one Bearer token, OpenAI-compatible chat/completions. Paid models require purchased tokens (no API access from the daily free pool).

Check the individual model pages — /apps/openai-gpt-4-1/ and /apps/mistralai-mistral-large-2411/ — for each model's specs. For head-to-head quality signal, look at the /arena/ leaderboard which ranks models by blind community votes. For your own workload, nothing beats sending the same prompts through the compare tool.
