Function: flarelogAI()

flarelogAI(logger, config?): AIInstrumentationHandle

Enable AI inference observability on a FlareLog instance.

By default, this:

Patches globalThis.fetch to intercept calls to OpenAI, Anthropic, and any user-configured extra hosts.
Injects the W3C traceparent header on outgoing AI calls so they correlate with the parent request span.
Captures token usage, latency (TTFB + total), cost in USD, tool calls, and errors.
Emits a structured log entry per call with flarelog.kind: "ai_call".

The instrumentation is global — calling flarelogAI(logger) twice with different loggers is undefined. Use one logger per process.

Parameters

a handle with a .dispose() method to remove instrumentation.
