…patible servers Registers a dedicated "local-mlx" provider driven by LOCAL_MLX_BASE_URL and LOCAL_MLX_MODEL_ID, alongside the generic local provider so an MLX endpoint (mx-openai-server / Rapid MLX) and an Ollama endpoint can coexist. Enables Qwen-style reasoning and the "system" role those servers require.

Greptile SummaryThe PR adds a deployment-wide MLX provider with MLX-compatible role and thinking settings, then attempts to expose it through both runtime and client model catalogs.
|
| Filename | Overview |
|---|---|
| packages/adapters/src/pi-local-provider.ts | Defines a keyless MLX provider with the required system-role and Qwen thinking compatibility. |
| packages/adapters/src/pi-models.ts | Adds MLX to the client catalog, but the resulting entry cannot be saved through credential-gated selection APIs. |
| packages/adapters/src/pi-runtime.ts | Registers the MLX provider in the lazy runtime model collection. |
| packages/adapters/src/pi-models.test.ts | Verifies catalog visibility but does not exercise the credential-gated API path needed to save the selection. |

When a deployment configures LOCAL_MLX_MODEL_ID, the runtime registers local-mlx, but listPiCatalog builds its separate model collection without that provider. The configured model is therefore runnable by the backend but absent from model settings, preventing users from selecting it through the normal UI.

listPiCatalog builds its own provider collection for the model picker; without registering local-mlx there, a configured MLX model runs but cannot be selected.

When a deployment configures LOCAL_MLX_MODEL_ID and a user selects the advertised local-mlx entry, the default and bot-update APIs require a stored user credential, while the connection flow cannot create one without an API key. Saving the model therefore fails with “No model credential is connected for local-mlx” or “Connect that model provider first,” leaving the configured model unselectable.

Why
Rakazo's generic
localprovider (RAKAZO_LOCAL_MODELS/RAKAZO_LOCAL_MODELS_URL) and the per-useropenai-compatibleconnect both target OpenAI-compatible servers, but neither encodes the compatibility settings MLX servers actually require:mlx-openai-server(and Rapid-MLX) rejects pi's default"developer"system role with a422; it only accepts"system".chat_template_kwargs.enable_thinking. Without a thinking-format hint, those servers default toreasoning_effort: "xhigh"and can burn the entiremaxTokensbudget on thinking before reaching an answer.The generic
localprovider setsreasoning: falseand nocompat; theopenai-compatibleprovider setssupportsDeveloperRole: falsebut disables reasoning and has no thinking-format option. Pointing either at an MLX model misbehaves out of the box. This adds a dedicated, deployment-widelocal-mlxprovider so an MLX endpoint and an Ollama endpoint can coexist, each with the right settings.What changed
