llm-catalog-core 0.5.0

Gateway-agnostic core for llm-catalog: config schema, resolver, GatewayTransport, and LiteLLM codegen. Knows nothing about any runtime adapter.

llm-catalog-core

Runtime-agnostic core for llm-catalog. It holds the config schema (shipped as schema.json for editor validation; parity with ai-sdk-catalog 0.7), validation, role resolution, the path-rewriting GatewayTransport, and native LiteLLM codegen.

This package knows nothing about any runtime adapter and never touches the filesystem, so installing it pulls in neither Pydantic AI nor LiteLLM. Use it directly when you only need resolution or codegen. Otherwise install one of the adapter distributions (llm-catalog-pydantic-ai, llm-catalog-litellm), which depend on this.

The config format is JSON, shared verbatim with ai-sdk-catalog — read the file yourself and hand the parsed mapping to Catalog, which validates it:

import json
from pathlib import Path

from llm_catalog.core import Catalog

config = json.loads(Path("llm-catalog.json").read_text(encoding="utf-8"))
cat = Catalog(config)
rm = cat.resolve_role("fast")   # -> ResolvedModel (no adapter types)
print(rm.kind, rm.vendor, rm.base_url)  # "gateway" or "direct"

To keep using YAML, parse it yourself (e.g. yaml.safe_load) and pass the result the same way.

See the repository README for the full picture, the public/private boundary, and the verification notes.
