Pre-router cache for classification-shaped completions with formal parity guarantee

[adrida]

Hey LiteLLM team,

Quick question on scope. I maintain TRACER (https://github.com/adrida/tracer) - an OSS package that learns a non-LLM surrogate from teacher classification traces and routes the easy majority off the LLM, with a formal parity guarantee (configurable target_teacher_agreement, e.g. 0.95).

For classification-shaped LiteLLM traffic (intent classification, content/policy checks, query routing), it could sit in front of litellm.completion(...) as a pre-router cache: surrogate handles 90%+, LLM only sees the uncertain tail.

Would you be open to a litellm.classification(...) helper or a worked example in the docs that wires TRACER in as a pre-router? Happy to draft the PR.

Also context: TRACER is now in prod at a known AI infra company, integrated by an agent reading the repo - happy to share details if useful.
