This PR adds Cheaper Inference as a community provider in config/provider-catalog.json.
It uses the same pattern as #1286.

Cheaper Inference is an OpenAI-compatible LLM gateway.
One API key gives access to models from several labs.

Usage: open Settings > Model Providers > Provider Store.
Install "Cheaper Inference" and paste an API key.

Details

Files: config/provider-catalog.json (one new entry, at the top like the PPIO entry).

Entry:

  • providerKey: openai
  • baseUrl: https://api.cheaperinference.com/v1
  • categories: ["llm"] (the gateway has no embedding API)
  • Descriptions in en and zh-CN.
  • Icon: https://www.cheaperinference.com/icon.svg.

Tests: biome check config/provider-catalog.json passes. The JSON parses.

Live check: gpt-5.4-mini returned a reply through ChatOpenAI from @langchain/openai 0.6.7 with the entry's baseUrl.
This is the same call path as providerKey: openai in packages/providers.
GET {baseUrl}/models also returns the model list, as listProviderItemOptions expects.

Change: Feature

Merge Risk: 🟡 Moderate · up to abe05

Production users will not see Cheaper Inference in the Provider Store because the upload workflow writes the catalog to a different path than production reads. Correct the publication path before merging.

Publish the provider catalog at the production URL path.

Production fetches https://static.refly.ai/config/provider-catalog.json, but the upload workflow writes this file to mcp-config/provider-catalog.json. Cheaper Inference will therefore not appear in production.

Suggested fix
-  await uploadState('config/provider-catalog.json', 'mcp-config/provider-catalog.json');
+  await uploadState('config/provider-catalog.json', 'config/provider-catalog.json');
