Providers
GPT-4o starts at $2.50 per million input tokens and $10.00 per million output tokens via Azure. See all 2 providers below with their per-token pricing, latency, throughput, and modality support.
| Provider | Input $/M | Cached input $/M | Output $/M | Context in / out | TTFT p95 s | Output p5 c/s | Modalities in / out |
|---|---|---|---|---|---|---|---|
 Azure | $2.50 | — | $10.00 | 128.0K/16.4K | 0.53 | — | / |
 OpenAI | $2.50 | — | $10.00 | 128.0K/16.4K | 0.50 | — | / |
Cached input is the discounted price for prompt tokens served from a provider cache. TTFT is time to first token. Output is characters per second; p5 is the sustained floor exceeded by 95% of observed requests.
