Strengths and limitations
Strengths
- Measured results (AA Intelligence 24.1 · Arena Elo 1200 · MMLU-Pro 73.6%) 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 6× 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.
Arena Elo, MMLU-Pro and pricing figures are illustrative; validate current vendor terms before purchase.
