| Parameter | Type | Description |
|---|---|---|
| max_tokens | integer | Maximum number of tokens to generate in the response. (≥1) |
| temperature | float | Controls randomness. Lower values make output more deterministic. (0–1) Default: 1. |
| top_p | float | Nucleus sampling threshold. Considers tokens with cumulative probability up to this value. (0–1) Default: 1. |
| stop_sequences | string | Up to 4 sequences where the model will stop generating. |
| top_k | integer | Only sample from the top K most likely tokens at each step. (0–500) Default: 250. |
| thinking.type | enum | Enable or disable extended thinking. Default: disabled. |
| thinking.budget_tokens | integer | Token budget for extended thinking. (1024–128000) |
Default mode. Pay per token with no upfront commitment.
Enables chain-of-thought reasoning before generating the final response.
