FreeVisionVideoStructured output

Supported parameters

max_tokens
Max tokens
Upper bound on generated tokens. Output stops at the limit.
response_format
Response format
For example json_object or json_schema, to constrain the shape.
seed
Seed
A fixed seed helps reproduce sampling. It does not guarantee byte-identical output.
temperature
Temperature
Sampling temperature. Lower is steadier, higher is more varied. Often 0 to 2.
top_p
Top-p
Sample only from tokens whose cumulative probability reaches top_p.
