Best for
- Multi-step reasoning and AIME-class math with visible thinking
- Competitive coding (LiveCodeBench ~71)
- Multimodal reasoning (added a vision encoder in 1.2)
- An open reasoning model you fully control
How it compares — and the India angle
- Standout self-host reasoning option for India: runs on a single RTX 4090 or 32GB Mac at 4-bit (~15-19GB).
- Zero USD billing when self-hosted, unlike API-only reasoning models.
- Magistral Medium 1.2 (proprietary API) scores higher for those who prefer managed access.
