Venice supports additional capabilities within it's models that can be powered by the `venice_parameters` input on the chat completions endpoint. In certain circumstances, you may be using a client that does not let you modify the request body. For those platforms, you can utilize Venice's Model Feature Suffix offering to pass flags in via the model ID. ## Syntax The Model Feature Suffix follows this pattern: ``` := ``` For multiple parameters, chain them with `&`: ``` :=&=&= ``` ## Examples ### To Set Web Search to Auto ``` default:enable_web_search=auto ``` ### To Enable Web Search and Disable System Prompt ``` default:enable_web_search=on&include_venice_system_prompt=false ``` ### To Enable Web Search and Add Citations to the Response ``` default:enable_web_search=on&enable_web_citations=true ``` ### To Enable Web Search with Full Page Scraping ``` default:enable_web_search=on&enable_web_scraping=true ``` ### To Use a Character ``` default:character_slug=alan-watts ``` ### To Hide Thinking Blocks on a Reasoning Model Response ``` qwen3-4b:strip_thinking_response=true ``` ### To Disable Thinking on Supported Reasoning Models Certain reasoning models (like Qwen 3) support disabling the thinking process. You can activate using the suffix below: ``` qwen3-4b:disable_thinking=true ``` ### To Add Web Search Results to a Streaming Response This will enable web search, add citations to the response body and include the search results in the stream as the final response message.
