    Strengths and limitations

    Strengths

    • Low input cost at $0.05 per million tokens suits high-volume workloads.
    • 524K context supports large documents, repositories and extended conversations.
    • Supports text & reasoning workloads in one model.

    Limitations

    • Generated tokens cost 4× 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.
