    Strengths and limitations

    Strengths

    • Measured results (AA Intelligence 47.6 · DesignArena Elo 1300 · Arena Elo 1266 · MMLU-Pro 84.6%) position it for demanding production work.
    • 1.1M context supports large documents, repositories and extended conversations.
    • Supports text & reasoning and code & slms and vision workloads in one model.

    Limitations

    • Generated tokens cost 5× 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.
