Parameters

ParameterTypeRequiredDefaultDescription
enable_thinkingbooleannotrueEnable extended thinking mode. Slower but improves reasoning-heavy tasks. A request that forces a tool call runs without reasoning unless it sets enable_thinking.
video_fpsnumberno-Frames per second to sample from video inputs. When omitted, the model’s own default applies. · Range: 0.1 – 10
media_resolutionenumno"default"Resolution at which video inputs are read. max reads finer detail and uses more input tokens. · Allowed: default, max
temperaturenumberno1.0Sampling temperature. 0 = deterministic, 1.5 = maximum randomness. · Range: 0 – 1.5
top_pnumberno0.95Nucleus sampling probability mass. Lower = more focused. · Range: 0.01 – 1
max_tokensnumberno8192Maximum tokens in the response. · Range: 1 – 131072
stopstringno-Up to 4 strings where the model will stop generating further tokens.
response_formatenumno-Constrain the output to valid JSON. Use JSON mode for any JSON object, or supply a JSON Schema to force an exact response shape.
web_search_linkupbooleannofalseOptional web search powered by Linkup. When enabled, recent web sources are retrieved using your latest user message as the query and provided to the model as additional context. Adds $0.013 per call when invoked on top of the model’s normal token cost. Disabled by default.
disable_formattingbooleannofalseReturn the answer without the Sources list that web search adds.

Notes

Accepts text, image, video, and audio input and returns text. Thinking is on by default and can be turned off. Optional Linkup web search is billed only when invoked.
