Deep dive
The capability footprint differs most on structured outputs: Mistral Large 3 675B Instruct. Both models share vision and multimodal input, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
For cost, Mistral Large 3 675B Instruct lists $0.50/1M input and $1.50/1M output tokens on the cheapest tracked provider, while Mistral Medium 3 Instruct lists $0.40/1M input and $2/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Mistral Large 3 675B Instruct lower by about $0.08 per million blended tokens. Availability is 6 providers versus 2, so concentration risk also matters.
Choose Mistral Large 3 675B Instruct when vision-heavy evaluation and broader provider choice are central to the workload. Choose Mistral Medium 3 Instruct when vision-heavy evaluation and lower input-token cost are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship. This keeps the decision grounded in measurable tradeoffs instead of brand-level assumptions.
