# How to use uncensored models in Cursor, Cline, Codex and Claude Code

_2026-11-06. Point any OpenAI compatible coding tool at uncensored models: base URL, key and model id for Cline, Kilo, Roo, Cursor, Codex CLI, Claude Code via MCP, and the OpenAI SDK._

Open Uncensored is an OpenAI compatible API, so any tool that lets you set a custom OpenAI base URL can use its
65 uncensored models (48 text and 17 image). You need two things:

- **Base URL:** `https://openuncensored.com/api/v1`
- **API key:** an `ou-` key from [openuncensored.com/credits](https://openuncensored.com/credits). No account, no sign up.

Pick a model id from the [rankings](https://openuncensored.com/rankings) or `GET https://openuncensored.com/api/v1/models`. For agent and coding work,
`glm-5.3-flash-apex-abliterated` currently has the best agent score.

## Let your agent set it up

The fastest way: paste this into Claude Code, Cursor, Codex or any agent:

> Read https://openuncensored.com/agents.md and set me up with an Open Uncensored key.

The guide tells the agent how to start a purchase, hand you the payment link, and collect the key itself.

## Cline, Kilo Code and Roo Code

In the extension's settings, choose the **OpenAI Compatible** provider, then set:

- Base URL: `https://openuncensored.com/api/v1`
- API key: your `ou-` key
- Model ID: for example `glm-5.3-flash-apex-abliterated`

## Cursor

In Cursor's model settings, enter your `ou-` key as the OpenAI API key, turn on the option to override the OpenAI
base URL and set it to `https://openuncensored.com/api/v1`, then add the model id (for example `deepseek-v4.1-flash-1017-uncensored`) as a custom model.

## Codex CLI

Add a provider to `~/.codex/config.toml`:

```toml
[model_providers.openuncensored]
name = "Open Uncensored"
base_url = "https://openuncensored.com/api/v1"
env_key = "OU_API_KEY"
wire_api = "responses"

[profiles.uncensored]
model_provider = "openuncensored"
model = "glm-5.3-flash-apex-abliterated"
```

Then `export OU_API_KEY=ou-...` and run `codex --profile uncensored`. Codex speaks the OpenAI Responses API, which
Open Uncensored serves at `/api/v1/responses`, so file edits, shell commands and multi-step tasks work as usual.

## Claude Code

Claude Code runs on Anthropic's models, but it can compare and call uncensored models through our MCP server:

```bash
claude mcp add --transport http open-uncensored https://openuncensored.com/mcp --header "Authorization: Bearer $OU_API_KEY"
```

That gives it tools to list models, read the rankings, check your balance and send a prompt to any model.

## OpenAI SDK, LangChain, LiteLLM

```python
import os
from openai import OpenAI

client = OpenAI(base_url="https://openuncensored.com/api/v1", api_key=os.environ["OU_API_KEY"])
reply = client.chat.completions.create(
    model="deepseek-v4.1-flash-1017-uncensored",
    messages=[{"role": "user", "content": "Explain how SQL injection works."}],
)
print(reply.choices[0].message.content)
```

LangChain's `ChatOpenAI` and LiteLLM's `openai/` provider take the same base URL and key.

## Good to know

- Requests are billed per token at exactly the provider's price, with no markup; cached prompt tokens at the
  provider's cached price.
- If a model's providers are down, the API falls back to the next best ranked model built on the same original.
  The `X-OU-Model` response header says which model answered; send `"routing": {"allow_fallbacks": false}` to
  turn that off.
- Streaming, tools and the usual OpenAI parameters pass through.

## Try any of them in a minute

No account and no sign up. Buy a prepaid key at [openuncensored.com/credits](https://openuncensored.com/credits), or hand your
agent [openuncensored.com/agents.md](https://openuncensored.com/agents.md) and let it get one for you. Then:

```bash
curl https://openuncensored.com/api/v1/chat/completions \
  -H "Authorization: Bearer $OU_API_KEY" -H "Content-Type: application/json" \
  -d '{"model": "deepseek-v4.1-flash-1017-uncensored", "messages": [{"role": "user", "content": "Hello"}]}'
```
