Strengths and limitations

Strengths

Priced at $1.25 input and $2.50 output per million tokens.
2M context supports large documents, repositories and extended conversations.
Supports text & reasoning and vision workloads in one model.

Limitations

Real-world cost still depends on prompt length, response length and provider-specific billing rules.
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.
