Key facts

Input price

Output price
$25.00 / 1M tokens
Context window
1M tokens
Max output
128K tokens
Accepts
Text, Images, Files
Returns

Example: 1,000 requests with 1,000 input and 500 output tokens each would cost about $17.50 (1M input tokens × $5.00 + 0.5M output tokens × $25.00). 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.
