Add the LiteLLM metric migration mapping.
The LLM_USAGE_TOKEN_TYPE row covers a separate SpanAttributes constant. The LiteLLM token histogram previously used SpanAttributes.GEN_AI_USAGE_TOKEN_TYPE and now uses GenAIAttributes.GEN_AI_TOKEN_TYPE. Add a mapping for this metric and keep the existing LLM_USAGE_TOKEN_TYPE row.

Not adding this row. MIGRATION.md covers the semconv-ai upgrade from v0.4.x to v0.5.x. This pull request changes no constant in that package. The row would also list GEN_AI_USAGE_TOKEN_TYPE under section 1, "Removed constants". Line 79, in section 2 ("stay in SpanAttributes"), records it as the new name of LLM_USAGE_TOKEN_TYPE.

The LiteLLM token histogram now tags
gen_ai.token.typethroughGenAIAttributes.GEN_AI_TOKEN_TYPE, as the OpenAI, Anthropic and Groq instrumentations do. Before,litellm/__init__.py:516and:521wrotegen_ai.usage.token_type. Values stayinputandoutput.Series keyed on the old name split at upgrade. Only 0.62.3 and 0.62.4 shipped it. No issue tracks this.
test_token_usage_metric_carries_token_typereads the histogram's data points from the in-memory reader, withmock_responseand no network.feat(instrumentation): ...orfix(instrumentation): ....@doronkopit5, the package came in with #4322.
MIGRATION.md:79still sendsLLM_USAGE_TOKEN_TYPEusers toGEN_AI_USAGE_TOKEN_TYPE, while line 37 mapsLLM_TOKEN_TYPEtoGenAIAttributes.GEN_AI_TOKEN_TYPE. Should row 79 move to the spec attribute, here or in a follow-up?Summary by CodeRabbit
gen_ai.token.typeinstead of the legacy attribute, making token type information consistent for telemetry consumers.
