Connect Pi

Pi is a minimal, extensible coding agent for your terminal (documentation). It connects to UncensoredGPT as a custom OpenAI-compatible endpoint in models.json. Setup takes about a minute.

1. Set your API key

Create a key in the Console if you don’t have one, then export it:

export UNCENSOREDGPT_API_KEY="sk-..."

Add the export to your shell profile (~/.bashrc, ~/.zshrc, …) to make it permanent.

2. Add the provider to models.json

Create or edit ~/.pi/agent/models.json (that’s the default agent directory; set PI_CODING_AGENT_DIR if you use a custom one):

{
  "$schema": "https://pi.dev/schemas/models.schema.json",
  "providers": {
    "uncensoredgpt": {
      "baseUrl": "https://api.uncensoredgpt.ai/v1",
      "api": "openai-completions",
      "apiKey": "$UNCENSOREDGPT_API_KEY",
      "models": [
        {
          "id": "uncensoredgpt/qwen3.8-27b-uncensored",
          "name": "Qwen3.8 27B Uncensored",
          "contextWindow": 262000,
          "reasoning": true
        },
        {
          "id": "uncensoredgpt/qwen3.6-35b-a3b-uncensored",
          "name": "Qwen3.6 35B A3B Uncensored",
          "contextWindow": 262000,
          "reasoning": true
        },
        {
          "id": "uncensoredgpt/gemma4-31b-uncensored",
          "name": "Gemma4 31B Uncensored",
          "contextWindow": 131072,
          "reasoning": true
        },
        {
          "id": "uncensoredgpt/gemma4-26b-a4b-uncensored",
          "name": "Gemma4 26B A4B Uncensored",
          "contextWindow": 131072,
          "reasoning": true
        },
        {
          "id": "uncensoredgpt/uncensoredgpt",
          "name": "UncensoredGPT",
          "contextWindow": 262000,
          "reasoning": true
        },
        {
          "id": "uncensoredgpt/qwen3.8-flash-next-cybersecurity",
          "name": "Qwen3.8 Flash Next Cybersecurity",
          "contextWindow": 262000,
          "reasoning": true
        },
        {
          "id": "uncensoredgpt/deepseek-v4.1-flash-uncensored",
          "name": "DeepSeek V4.1 Flash Uncensored",
          "contextWindow": 1000000,
          "reasoning": true
        },
        {
          "id": "uncensoredgpt/glm-5.3-flash-uncensored",
          "name": "GLM 5.3 Flash Uncensored",
          "contextWindow": 1000000,
          "reasoning": true
        },
        {
          "id": "uncensoredgpt/glm-5.3-uncensored",
          "name": "GLM 5.3 Uncensored",
          "contextWindow": 1000000,
          "reasoning": true
        },
        {
          "id": "uncensoredgpt/neuralnet-free-model",
          "name": "NeuralNet Free Model",
          "contextWindow": 200000
        }
      ]
    }
  }
}

apiKey: "$UNCENSOREDGPT_API_KEY" is resolved from the environment at request time — the key itself never lands on disk.

3. Start Pi

cd /path/to/your/project
pi

Run /model and the UncensoredGPT models appear in the picker. Press Ctrl+S on one to save it as your default.

How model references work

Pi addresses models as <provider>/<model-id>. Because our model IDs already contain a slash (uncensoredgpt/...), the full reference has three segments:

pi --model uncensoredgpt/uncensoredgpt/glm-5.3-flash-uncensored

The first segment is the provider key from models.json (uncensoredgpt); the rest is the model ID exactly as the API expects it.

Notes

Trim the models array to just the models you use.
contextWindow values are the conservative per-model limits from the coding agents overview. Add maxTokens only if you want to cap output tokens explicitly.
All models support tool calling and streaming, so agent features work fully.
