Model Feature Suffix

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:

<model_id>:<parameter>=<value>

For multiple parameters, chain them with &:

<model_id>:<parameter1>=<value1>&<parameter2>=<value2>&<parameter3>=<value3>

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:

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.
