Inputobject

audio	string	Input audio to send with the prompt (max 1 audio file, up to 8.4 hours)	format: uri · default: null
top_p	number	Nucleus sampling parameter - the model considers the results of the tokens with top_p probability mass	0 ≤ n ≤ 1 · default: 0.95
images	string[]	Input images to send with the prompt (max 10 images, each up to 7MB)	default: []
prompt*	string	The text prompt to send to the model
videos	string[]	Input videos to send with the prompt (max 10 videos, each up to 45 minutes)	default: []
video_fps	number	Frame rate (frames per second) at which to sample input videos. Higher values give the model more frames to reason over (useful for fast-moving footage) but consume more tokens. Omit to use the default sampling rate (1 fps).	0.1 ≤ n ≤ 60 · default: null
temperature	number	Sampling temperature between 0 and 2	0 ≤ n ≤ 2 · default: 1
thinking_level	enum	An enumeration.	none \| low \| high
max_output_tokens	integer	Maximum number of tokens to generate	1 ≤ n ≤ 65535 · default: 65535
