VERSION GUIDE
Compare Max versions
Compare model use cases, context limits, and standard token prices.
| Version | Status | Best fit | Context | Max output | Input / 1M | Output / 1M |
|---|---|---|---|---|---|---|
| 2.0 | Available | Coding, agents, and documents | 1M | 128K | $3.00 | $20.00 |
| 1.0 | Available | Reasoning and agents | 1M | 128K | $3.00 | $20.00 |
Prices are in USD per million tokens at standard context rates. See each model's pricing details for cached-input and long-context rates.
Pricing
USD per million tokens, excluding applicable taxes.
| Context tier | Input | Cached input | Output |
|---|---|---|---|
| Standard, prompt ≤ 200K | $3.00 | $0.30 | $20.00 |
| Long context, prompt > 200K | $6.00 | $0.60 | $30.00 |
When input exceeds 200K tokens, long-context rates apply to the entire request. Tokens generated through internal multi-model collaboration are not billed. Usage is reported by the API.
