## Tracked benchmark scores

| Benchmark | Score | Source | What it measures |
| --- | --- | --- | --- |
| BullshitBench v2 | 2% | [BullshitBench](https://github.com/petergpt/bullshit-benchmark) | Given a confidently-worded but nonsensical prompt, does the AI spot that it makes no sense and push back — instead of playing along and inventing an answer? The score is how often it clearly called out the nonsense. Higher is better. |

## About Mistral Large 3

Mistral Large 3 was released on December 2, 2025 as a sparse mixture-of-experts model with 675 billion total parameters and 41 billion active per token. It marked Mistral's return to a large sparse architecture after the Mixtral line. The release combined multilingual language capabilities with image understanding in a flagship model available as downloadable weights.

Mistral published both base and instruction-tuned versions under Apache 2.0, alongside compressed deployment formats and hosted access. The launch model was instruction-oriented; Mistral described a reasoning version as future work rather than a feature already supplied by that checkpoint. Its sparse computation reduced the active work per token, but serving still required infrastructure appropriate to the complete model and chosen precision.
