Mistral Large 4
mistral · Lanzado oct 2026
Conditional: Mistral Large 4 is a public preview, not a finished release, since Mistral says its reinforcement learning run is still in flight and promises weights "by the end of the month". It is a mixture-of-experts model of about 1 trillion parameters, 52B active, with a 1M context on its docs page and a $1.36 input, $4.18 output list price per 1M tokens. Most benchmarks are Mistral's own. Trial it now if you want an open-weight-bound model, but wait for weights and licence before committing.
¿Es adecuada para ti?
Bueno para
- Trying out a 1.05T-parameter, 52B-active mixture-of-experts model with text and image input through Mistral Studio while it is in public preview
- Long-document and agent work that needs a 1M-token context (per the docs model page)
- Teams that want an open-weight path: Mistral says weights follow by the end of the month
- Apps that need function calling, structured outputs, document QnA and batching, all listed on the docs model page
No recomendado para
- Production commitments: this is a public preview and Mistral says the RL run behind it is still in flight
- Self-hosting today: no weights are out and no licence was published on the pages we read
- Decisions that need independent evaluations: most scores are Mistral's own, and Mistral ran the blind human coding evaluation with Surge AI
- Budgeting off the docs page alone, which shows a sale rate that differs from the announcement's list rate
Rendimiento por tarea
Agentic coding
DeepSWE 1.1 61.7% and Terminal Bench 4.0 28.3% are Mistral's numbers; Mistral's blind human evaluation with Surge AI ranks it second at 3.74/5 behind Claude Opus 5 at 4.22; untested by us
Cybersecurity
Mistral reports 93% of the 40 Cybench challenges and 82% on one test of the AA Cyber Index (reproduce a real open-source vulnerability, then patch it); both are Mistral's numbers, and the 82% is one test, not the index overall; untested by us
