Strengths and limitations

Strengths

Low input cost at $0.15 per million tokens suits high-volume workloads.
A 128K context window covers most focused application workflows.
Supports text & reasoning and vision workloads in one model.

Limitations

Generated tokens cost 4× more than input tokens, which matters for verbose responses.
The 128K context window is smaller than several long-context alternatives.
Arena Elo and MMLU-Pro are directional; test accuracy, latency and reliability on your own workload before committing.
