#+TITLE: SKILL: LLM Gateway (org-skill-llm-gateway.org)

|
* Overview
|
|
The LLM Gateway dispatches inference requests to the registered probabilistic backends. It receives a prompt and system prompt, looks up the provider's registered function from ~*probabilistic-backends*~, calls it with the given model, and returns the result. This is the thin routing layer that sits between the reason pipeline and the provider-specific implementations in the unified-llm-backend skill.
