Projected monthly cost

Rows open both models in the calculator — adjust volume and token counts there.

Very low latency for high-volume, simple tasks — classification, short summaries, and lightweight chat where response time matters more than depth.

Noticeably weaker on multi-step reasoning and long-context synthesis; pairing with a larger model for escalation is common.

Native audio, video, and document understanding with a ~1M token context window — strong fit for multi-modal RAG and large-document analysis.

Output token cost is steep relative to input, and the largest context windows can be slow to fill — chunk large documents where possible.

Vendor list rates · per-request examples assume 1,200 input + 400 output tokens.
