 #### Required Parameters
 - **`--provider`**: Main generation model provider (e.g., openai, anthropic, etc.) - Default: "openai"
-- **`--model`**: Main generation model name (e.g., o3-2025-04-16) - Default: "o3-2025-04-16"
+- **`--model`**: Main generation model name (e.g., gpt-5-2025-08-07) - Default: "gpt-5-2025-08-07"
 - **`--ground_provider`**: The provider for the grounding model - **Required**
 - **`--ground_url`**: The URL of the grounding model - **Required**
 - **`--ground_model`**: The model name for the grounding model - **Required**
 - **`--grounding_width`**: Width of the output coordinate resolution from the grounding model - **Required**
 - **`--grounding_height`**: Height of the output coordinate resolution from the grounding model - **Required**
 
+#### Optional Parameters
+- **`--model_temperature`**: The temperature to fix all model calls to (necessary to set to 1.0 for models like o3 but can be left blank for other models)
+
 #### Grounding Model Dimensions
 The grounding width and height should match the output coordinate resolution of your grounding model:
 - **UI-TARS-1.5-7B**: Use `--grounding_width 1920 --grounding_height 1080`
