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.

​

Instructions
