-## Provider Notes
-
-Do not ask users to paste API keys into chat. If configuration is needed, describe the fields; LLM provider and BYOK changes are hot-reloaded for new turns.
-
-For OpenRouter, the image tool expects:
-
-```json
-{
-  "providers": {
-    "openrouter": {
-      "apiKey": "sk-or-..."
-    }
-  },
-  "tools": {
-    "imageGeneration": {
-      "enabled": true,
-      "provider": "openrouter",
-      "model": "openai/gpt-5.4-image-2"
-    }
-  }
-}
-```
-
-For AIHubMix, the image tool expects:
-
-```json
-{
-  "providers": {
-    "aihubmix": {
-      "apiKey": "sk-..."
-    }
-  },
-  "tools": {

-      "enabled": true,
-      "provider": "aihubmix",
-      "model": "gpt-image-2-free"
-    }
-  }
-}
-```
-
-AIHubMix `gpt-image-2-free` uses AIHubMix's unified predictions endpoint internally (`/v1/models/openai/gpt-image-2-free/predictions`), not the OpenAI Images `/v1/images/generations` endpoint. If it fails with "Incorrect model ID", do not assume the key lacks permission until the provider config, model name, and gateway restart have been checked.
-
-`providers.aihubmix.extraBody` can be used for provider-specific options. For example, `"extraBody": {"quality": "low"}` is optional but can make `gpt-image-2-free` faster and less likely to time out.
-
-For Gemini, the image tool supports two model families. Imagen 4 (`imagen-4.0-generate-001`) supports text-to-image only. Gemini Flash (`gemini-2.5-flash-image`) also supports reference-image edits. Configuration:
-
-```json
-{
-  "providers": {
-    "gemini": {
-      "apiKey": "AIza..."
-    }
-  },
-  "tools": {
-    "imageGeneration": {
-      "enabled": true,
-      "provider": "gemini",
-      "model": "imagen-4.0-generate-001"
-    }
-  }
-}
-```
-
-For Gemini models, `defaultImageSize` has no effect; use `defaultAspectRatio` instead. Imagen 4 supports `1:1`, `9:16`, `16:9`, `3:4`, and `4:3`.
