# Venice models (group vn)

> Original: https://api.6io.io/en/docs/venice/ (HTML). All pages: https://api.6io.io/llms.txt

The `vn` group gives access to the chat models of [Venice](https://docs.venice.ai/). A model name is `vn/<Venice model ID>`, for example `vn/llama-3.3-70b`. Requests and responses are OpenAI-compatible: `POST /v1/chat/completions` (see [Chat](https://api.6io.io/md/en/chat.md)).

The request body is passed to Venice as it is, so the parameters are described in the Venice documentation: [Chat Completions](https://docs.venice.ai/api-reference/endpoint/chat/completions) and [API Specification](https://docs.venice.ai/api-reference/api-spec) (the Venice-specific `venice_parameters` are there too). The list of Venice models is in [List Models](https://docs.venice.ai/api-reference/endpoint/models/list) and its prices in [Pricing](https://docs.venice.ai/overview/pricing). Here you get the same models with prices in credits.

## Finding a model

`GET /v1/models` returns every model on sale with prices in credits. Venice models start with `vn/`. There is no provider choice as in OpenRouter: Venice runs its own models.

## How it differs from a plain chat

- **The Venice system prompt is off.** By default Venice adds its own prompt, about 1500 tokens on every request, and you would pay for them. Turn it on with `venice_parameters.include_venice_system_prompt: true`.
- **Paid search is not accepted.** Web search, page scraping and X search (`venice_parameters.enable_web_search`, `enable_web_scraping`, `enable_x_search`) and suffixes in the model name (`model:parameter=value`) are refused for now with `400 unsupported_parameter` or `404 model_not_found`: their cost is not part of the reserve.
- **Models with client-side encryption** (`e2ee-…`) are not on sale.
- **All other `venice_parameters` and request parameters** are passed on as they are.
- **Price.** Venice reports the cost in the `cost` field of the response (`usd` and `diem`). If the cost is not in dollars (`diem` is not zero), you get the result at once and the money for the request is closed after a check (status `billing_pending`, then `billing_review`); see [Balance and prices](https://api.6io.io/md/en/billing.md).

Free models (price 0) work while the API balance is above zero: see [Chat](https://api.6io.io/md/en/chat.md).
