Strengths & weaknesses
Strengths
- One small model covers reasoning, vision and coding instead of three separate ones
- Fits on a single GPU under a permissive licence
- Reasoning can be switched off entirely for latency-sensitive work
Weaknesses
- A fast generalist with a real depth ceiling — it won't reason its way out of a hard problem
- Merging three previous lines means it is rarely the best at any one of them
256k context and $0.15/$0.60 pricing per Mistral's announcement (earlier trackers listed 128k). MMLU-Pro 78.0 / GPQA 71.2 third-party-reported; LMArena Elo 1358 via BenchLM's Arena tracking.
