v2 accepted generation(id=...). v4 derives the observation id from the OTel
span id, so the isolated tracer provider now carries an id generator that
hands out the id start_generation asked for through a context variable, and
the callback passes the resolved generation_id metadata into it.
The legacy e2e suite patched httpx.Client.post and compared v2 ingestion
batches; it now patches requests.Session.post, decodes the OTLP protobuf
and compares the exported generation against regenerated fixtures. The
local readback test replaces the removed get_generations() with
api.observations.get_many() and polls Langfuse Cloud instead of sleeping.

Replace the v2 trace()/generation()/span() calls with SDK v4 observations exported over OpenTelemetry, with one isolated tracer provider per Langfuse credential set, a discarding exporter for mock mode, and v4 trace and observation id normalization. Keeps the session-header trace provenance logic from main so each call under a session alias still gets its own trace

The request path used get_end_user_object, which falls back to a database
lookup on a cache miss. Read the LiteLLM_EndUserTable row auth already cached
instead, with the default budget already attached, and leave misses to the
periodic refresh

The metric attribute filter now removes every attribute whose value is
None, and the content and inference-details events pass their attributes
through drop_none before emitting, so a call with no provider label or no
model name never hands the OTLP exporter a NoneType attribute. This closes
the gen_ai.request.model report on #36759 the same way the gen_ai.system
one was closed, and the regression tests cover both keys.
The pre-call hook passed the proxy's whole per-request metadata dict into the
request identity, so proxy-owned siblings such as requester_ip_address were
promoted alongside the caller's keys. Only the requester_metadata mapping is
read now, keyed under its wrapper, which keeps the default allowlist behaviour
unchanged

Mirror the key, team, user and org budget gauges for customer objects with
litellm_remaining_customer_budget_metric, litellm_customer_max_budget_metric
and litellm_customer_budget_remaining_hours_metric. The gauges carry only the
end_user label, are emitted after each request and from the startup budget
refresh for every customer with a budget attached, and reuse the
enable_end_user_cost_tracking_prometheus_only opt-in and end_user series caps

Strip only the proxy's requester_metadata. wrapper from an allowlisted key so
requester_metadata.trace_id lands as litellm.metadata.trace_id while other
dotted keys keep their full path and cannot collide on a shared leaf name

baggage_metadata_keys entries such as requester_metadata.trace_id now resolve the caller's nested metadata.trace_id and stamp it on the LLM-call span as litellm.metadata.trace_id, in both the OTEL v2 logger and the legacy OpenTelemetry callback. Nested metadata mappings are flattened to dotted paths, only allowlisted leaves are promoted, and the requester_metadata blob itself is never promoted

Pass user_api_key_dict.parent_otel_span into the outgoing W3C injection so the
legacy otel callback propagates its litellm_request span, falling back to the
otel_v2 request root span and then the ambient span. Extend the mapped unit
tests to assert the propagated trace and span ids over real captured headers
for HTTP and WebSocket passthrough with forwarding on and off.

Invalid or unknown virtual keys were filtered out of the proxy failed and total
request counters entirely. Count them with hashed_api_key unset so caller-chosen
key strings cannot create unbounded label series, and normalize the request
route on the auth failure path so dynamic path ids do not leak into the route
label either.

Pre-call limiters reject before a deployment is attached to request_data, so
the failure hook could not resolve api_provider for router aliases and emitted
api_provider="None" on litellm_proxy_failed_requests_metric_total and
litellm_proxy_total_requests_metric_total. Fall back to the provider the
limiter already resolved onto RateLimitError.llm_provider, keeping request
data as the first source and ignoring the proxy placeholder.

* fix(guardrails): log mask when a guardrail adds request keys
_inputs_were_modified only compared keys present in the pre-hook baseline, so a
guardrail that injected a new key such as tools was logged as allow. Compare over
the union of both key sets, and narrow the pre_call return value to the same
prompt-bearing keys the baseline holds so passthrough stays allow.

* perf(auth): prefetch user, team, membership, org and project in one MGET, one query and one pipeline
Auth read each object with its own Redis GET and, on a miss, its own DB
query, then the admission spend counters with one GET each. The prefetch
warms every entry the checks read with one MGET, one raw query for the
Redis misses and one pipeline write, and a per-request batch serves the
spend counter reads from one MGET. The per-object getters stay the
readers and the fallback, so enforcement does not depend on the prefetch

* perf(proxy): batch post-call spend counter reads and carry budget state through the request
Post-call warm checks, reservation reads and reconcile reads for one request now go through a task-local spend counter batch: one MGET answers every counter, successful increments write their result back into the batch so no second Redis read follows, and invalidation forgets the key. RedisCache.async_increment sends INCRBYFLOAT and its TTL command in one pipeline round trip.
Auth pins frozen team, user and org budget snapshots on UserAPIKeyAuth, the pre-call setup writes them into the request metadata, and Prometheus reads them back instead of calling get_key_object, get_team_object, get_user_object and get_org_object on the response path. The getters stay as the fallback for requests that carried nothing (custom auth, unauthenticated routes, skipped checks).

* perf(proxy): reconcile the budget reservation and the post-call warm checks from one MGET and one pipeline
A scope opened inside an open spend counter batch binds into it instead of starting its own, so the reservation reconcile and the post-call warm checks share the request's single MGET. The reconcile reads every reserved counter concurrently, sends the consistent adjustments in one INCRBYFLOAT+EXPIRE pipeline and settles a flushed or reseeded counter on its own afterwards, keeping the pre-call resize fail-closed. PendingSpendIncrement moves to spend_counter_batch so budget_reservation can build a pipeline without importing a private name
