📝 WalkthroughWalkthroughLM Studio metadata now describes local API formats and privacy properties. Its two model examples are inactive historical entries. Pricing metadata uses verified direct sources, zero-cost local inference notes, and an effective end date. ChangesLM Studio catalog updates
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR changes LM Studio’s local-runtime metadata, but the current values may cause consumers to use the wrong authentication variable or endpoint for the native API, leading to failed requests.

For consumers classifying LM Studio from provider metadata, this new self-hosted description conflicts with the unchanged gateway_kind: "catalogue"; apps/web/scripts/importer/v2.ts copies that value verbatim, while the catalog type explicitly supports self_hosted. Set the gateway kind accordingly so the reconciliation does not continue presenting LM Studio as an external fixed catalogue.

🌐 Web query:
site:lmstudio.ai/docs LM_API_TOKEN LMSTUDIO_API_KEY authentication environment variable
💡 Result:
The official environment variable used for authentication with LM Studio is LM_API_TOKEN [1][2]. LM Studio does not require authentication by default [1][3]. If you choose to enable API Token authentication for increased security (which can be toggled in the Server Settings within LM Studio) [4][5], you must provide a valid token. For the SDKs (Python and TypeScript), the LM Studio client automatically detects and uses the LM_API_TOKEN environment variable when it is set [1][2]. For direct REST API requests, you must include the token in the Authorization header using the Bearer scheme: Authorization: Bearer $LM_API_TOKEN [4][3] There is no standard environment variable named LMSTUDIO_API_KEY used by the official LM Studio documentation or SDKs; LM_API_TOKEN is the correct identifier [1][2][4].

Use the documented token environment variable.
Replace LMSTUDIO_API_KEY with LM_API_TOKEN. Consumers that follow auth_env otherwise receive an unsupported authentication variable for LM Studio SDK requests.

Separate the native and compatibility base URLs.
api_base_url is copied as metadata, and no consumer resolves URLs per api_formats. The declared /v1 base supports LM Studio’s compatibility APIs, while lmstudio.rest.v1 uses /api/v1. Remove the native format or add explicit format-specific endpoint support.

Summary
Reconciliation
LM Studio's public developer API lists models installed on the operator's system. The existing
openai/gpt-oss-20bandqwen/qwen3-30b-a3b-2507records came from models.dev and incorrectly resembled a fixed hosted catalogue. They remain in history with disabled routing and an effective end date. No cloud model catalogue was added because LM Studio's paid cloud models are documented as an in-app Bionic feature, not as this localhost developer API offer.No OpenAPI or generated enum changed:
lmstudioalready exists as a provider ID, and these routes were never active gateway routes.Validation
