Pricing per 1M tokens
| Item | Price / 1M tokens |
|---|---|
| Input | $0.50 |
| Output | $1.50 |
| Cache read | $0.05 |
| Batch inputBatch requests | $0.25 |
| Batch outputBatch requests | $0.75 |
Note: Batch prices come from the pricing page's Batch mode, which applies a factor of 0.5 to standard prices. Priority Tier adds 75% and regional inference adds 10%. The API docs give the context only as '256k'. The official weights card uses 262144 as the default vLLM max-model-len, and the Vercel AI Gateway also lists 262144. No primary page states a max output for the API. This is the previous flagship, still sold and priced alongside Large 4.
