What it excels at
Handles high-volume batch workloads with 400k context and 128k output at low per-token cost for text and vision inputs.
The business tradeoff
Lower reasoning capability than full GPT models; batch-only access adds scheduling latency and reduces suitability for interactive use.
Cheaper from OpenAI
