Strengths and limitations

Strengths

Low input cost at $0.10 per million tokens suits high-volume workloads.
1M 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.
