Strengths and limitations

Strengths

Measured results (quality score 90 · Arena Elo 1255 · MMLU-Pro 82.8%) position it for demanding production work.
400K context supports large documents, repositories and extended conversations.
Supports text & reasoning and code & slms and vision workloads in one model.

Limitations

Generated tokens cost 8× more than input tokens, which matters for verbose responses.
Large context capacity does not guarantee consistent retrieval across the entire prompt.
Arena Elo and MMLU-Pro are directional; test accuracy, latency and reliability on your own workload before committing.
