Interface: SessionUsage
Defined in: core/runner.ts:63
Running totals for the whole query() session so far, not for one turn: the SDK's own
total_cost_usd and modelUsage are cumulative across turns in a streaming-input
session, so the latest turn-end carries the session total (never sum them).
Properties
| Property | Type | Description | Defined in |
|---|---|---|---|
cacheReadTokens? | number | The part of inputTokens read from the cache: the context sent again on every call. It grows with each call while the context barely does, so the chat shows it apart. | core/runner.ts:70 |
costUsd | number | An estimate, not a billing statement. | core/runner.ts:73 |
inputTokens | number | Input tokens, cache reads and writes included, across every model the session used. | core/runner.ts:65 |
outputTokens | number | - | core/runner.ts:71 |
