Timing and throughput of a step.

Fields

step_time: Duration

Wall time of the whole step (model call and tool executions).

response_time: Duration

Time from the request until the response (or stream end).

time_to_first_output: Option<Duration>

Streaming: time until the first content part.

output_tokens_per_second: Option<f64>

Streaming: output tokens per second after the first output.

effective_output_tokens_per_second: f64

Output tokens divided by the response time.

input_tokens_per_second: Option<f64>

Streaming: input tokens divided by the time to first output.

effective_total_tokens_per_second: f64

Input plus output tokens divided by the response time.

time_between_output_chunks: Option<ChunkTimingStats>

Streaming: statistics of the gaps between content parts.

Implementations

impl StepPerformance

pub fn tokens_per_second(tokens: Option<u64>, duration: Duration) -> f64
