-### Supported Transforms
+## Features
 
-OpenRouter provides an [optional "middle-out" message transform](https://openrouter.ai/features/message-transforms) to help with prompts that exceed the maximum context size of a model. You can enable it by checking the "Compress prompts and message chains to the context size" box.
+- **Message transforms:** Enable "Compress prompts and message chains to context size" to handle large prompts
+- **Prompt caching:** Automatically passes caching to supported models
+- **Gemini caching:** Manually enable "Enable Prompt Caching" for Gemini models
 
-### Tips and Notes
+## Notes
 
--   **Model Selection:** OpenRouter offers a wide range of models. Experiment to find the best one for your needs.
--   **Pricing:** OpenRouter charges based on the underlying model's pricing. See the [OpenRouter Models page](https://openrouter.ai/models) for details.
--   **Prompt Caching:**
-    -   OpenRouter passes caching requests to underlying models that support it. Check the [OpenRouter Models page](https://openrouter.ai/models) to see which models offer caching.
-    -   For most models, caching should activate automatically if supported by the model itself (similar to how Requesty works).
-    -   **Exception for Gemini Models via OpenRouter:** Due to potential response delays sometimes observed with Google's caching mechanism when accessed via OpenRouter, a manual activation step is required _specifically for Gemini models_.
-    -   If using a **Gemini model** via OpenRouter, you **must manually check** the "Enable Prompt Caching" box in the provider settings to activate caching for that model. This checkbox serves as a temporary workaround. For non-Gemini models on OpenRouter, this checkbox is not necessary for caching.
+- **Pricing:** Based on underlying model pricing. See [OpenRouter Models](https://openrouter.ai/models)
