Prompting tips for Mistral Large 3 2512
- Be explicit and show the shape of the answer. Spell out format, tone and constraints up front, and include one short example of the output you want — Mistral Large 3 2512 follows concrete instructions better than abstract ones.
- Huge 262K context — but anchor the ask. You can paste whole documents or codebases; models attend most to the start and end, so put the key instruction at the top and restate it after long inputs.
- It reads images. Send image parts alongside your text and ask for specific outputs (named JSON fields, a table, "what changed") rather than "describe this".
- Give it real tools. Pass a
tools=[...]schema instead of asking it to "pretend" — let Mistral Large 3 2512 emit tool calls, execute them, and feed results back for the next turn. - Constrain JSON with a schema. Use
response_format/ structured outputs rather than "reply in JSON" to get valid, parseable objects every time.
Tips are derived from Mistral Large 3 2512's actual capabilities — context window, tool & JSON support, modality and price tier — not generic advice.
