Struct GenAiResponse 

pub struct GenAiResponse {
    pub model: Option<String>,
    pub finish_reason: Option<String>,
    pub input_tokens: u64,
    pub output_tokens: u64,
    pub cache_read_tokens: u64,
    pub cache_write_tokens: u64,
}

What a GenAI operation answered, for the span attributes of that name.

Every field is optional or zero-valued because a provider may report any subset: a wire that names no model leaves model absent rather than repeating the request’s, which would hide the one substitution the convention defines gen_ai.response.model to expose.

Fields

model: Option<String>

The model that actually answered, where the wire says.

finish_reason: Option<String>

Why generation stopped, in the provider’s own words.

input_tokens: u64

output_tokens: u64

cache_read_tokens: u64

Of input_tokens, how many were served from a provider-managed cache.

cache_write_tokens: u64

Of input_tokens, how many were written into one.
