Key facts
- Input price
- $1.25 / 1M tokens
- Output price
- $4.25 / 1M tokens
- Context window
- 1M tokens
- Max output
- 944K tokens
- Accepts
- Text, Images, Files, Video
- Returns
- Text
Example: 1,000 requests with 1,000 input and 500 output tokens each would cost about $3.38 (1M input tokens × $1.25 + 0.5M output tokens × $4.25). Estimate your own usage.
Prices are the provider’s own per-token rates with zero markup, from our price list as of Oct 18, 2026. If a call has extra provider charges (images, audio, web search, cached prompts), you pay the reported cost.
