 Fabro's catalog is the [lithos-llm](https://docs.rs/lithos-llm) built-in catalog. The `[llm]` table in settings is a second layer over it: a lithos catalog overlay that adds providers and models or changes existing entries. Later layers win. Tables merge key by key and every other value replaces. Models are nested under their provider, so two providers can expose the same model id without overwriting each other.

The coding harness a model expects lives under `metadata.agent`, a namespace lithos ships and other agents such as Pebble read too. See [Settings Configuration](/reference/user-configuration#llm) for every key.

 ### Provider adapters
 
-Providers are lithos adapters selected by the catalog `adapter` id: `anthropic`, `openai`, `gemini`, `openai-compatible`, and `bedrock`. A new OpenAI-compatible endpoint needs a catalog entry, not code.
+A provider names one lithos adapter in `adapter` (`http`, the default, or `bedrock`) and lists the wire codecs its host speaks in `codecs` (`openai-chat`, the default, `openai-responses`, `anthropic-messages`, `gemini-generate`, or `bedrock-converse`). A new OpenAI-compatible endpoint needs a catalog entry, not code.
 
 To add a custom transport, implement the lithos `ProviderAdapter` trait and register it with `ClientOptions::with_adapter`. `fabro_llm::gateway::GatewayAdapter` is Fabro's own example: it posts each request to a Fabro server's completions endpoint, which returns lithos `Response` JSON and streams lithos `StreamEvent` JSON verbatim.
