Function video_body 

pub fn video_body(
    model: &str,
    mime: &str,
    bytes: &[u8],
    prompt: &str,
    max_tokens: usize,
) -> Value

2026-09-26: One streamed request carrying a single video, then prompt.

Temperature 0 and thinking off, as in the vision benchmark’s request::body: the assertions are about what the model saw, and a reasoning block can use the whole token budget and leave empty content.
