}

Accumulated session usage metrics, including premium request cost, token counts, model breakdown, and code-change totals.

Experimental. This type is part of an experimental wire-protocol surface and may change or be removed in future SDK or CLI releases.

Fields

code_changes: UsageMetricsCodeChanges

Aggregated code change metrics

current_model: Option<String>

Currently active model identifier

last_call_input_tokens: i64

Input tokens from the most recent main-agent API call

last_call_output_tokens: i64

Output tokens from the most recent main-agent API call

model_metrics: HashMap<String, UsageMetricsModelMetric>

Per-model token and request metrics, keyed by model identifier

session_start_time: String

ISO 8601 timestamp when the session started

token_details: Option<HashMap<String, UsageMetricsTokenDetail>>

Session-wide per-token-type accumulated token counts

total_api_duration_ms: i64

Total time spent in model API calls (milliseconds)

total_nano_aiu: Option<f64>

Session-wide accumulated nano-AI units cost

total_premium_request_cost: f64

Total user-initiated premium request cost across all models (may be fractional due to multipliers)

total_user_requests: i64

Raw count of user-initiated API requests
