Parameters

ParameterTypeRequiredDefaultDescription
temperaturenumberno0.7Sampling temperature. 0 is deterministic and 2 is maximum randomness. · Range: 0 – 2
top_pnumberno0.9Nucleus sampling probability mass. Lower values make outputs more focused. · Range: 0 – 1
max_tokensnumberno4096Maximum output tokens. · Range: 1 – 64000
stopstringno—Up to 4 strings where the model will stop generating further tokens.
enable_thinkingbooleannotrueEnable reasoning before answering.
thinking_budgetnumberno32768Maximum tokens reserved for reasoning when thinking is enabled. · Range: 1 – 80000
reasoning_effortenumno"medium"Reasoning effort level. none disables thinking. low, medium, high, and max set bounded thinking budgets sized to the selected model. Sent as an OpenAI-style reasoning_effort field, translated into enable_thinking and thinking_budget for the model service. · Allowed: none, low, medium, high, max
vl_high_resolution_imagesbooleannotrueUse higher resolution processing for image inputs.
max_pixelsnumberno2621440Maximum pixel count per image when high resolution processing is disabled. · Range: 4096 – 16777216
video_fpsnumberno2Frames per second to sample from video inputs. · Range: 0.1 – 10
tool_web_searchbooleannofalseSearch the web for real-time information. Adds $0.01 to the request cost when enabled.

Notes

Supports text, image, and video input. Web search is available through tool_web_search and adds $0.01 per request when enabled. Thinking tokens are billed as output tokens.
