Claude Code Haha

Use Claude Code with any LLM — not just Claude.

OpenClaude is a fork of the Claude Code source leak (exposed via npm source maps on March 31, 2026). We added an OpenAI-compatible provider shim so you can plug in GPT-4o, DeepSeek, Gemini, Llama, Mistral, or any model that speaks the OpenAI chat completions API. It now also supports the ChatGPT Codex backend for codexplan and codexspark.

All of Claude Code's tools work — bash, file read/write/edit, grep, glob, agents, tasks, MCP — just powered by whatever model you choose.

Installation

You can install OpenClaude globally via npm:

npm install -g @quantum-ai/cc-haha

Once installed, the cc-haha command will be available.

Alternatively, you can use npx without global installation:

npx cc-haha

Quick Start (OpenAI-Compatible Mode)

To use OpenClaude with an OpenAI-compatible provider (such as OpenAI, DeepSeek, or a local model), set the following environment variables:

# Enable OpenAI compatibility mode
set CLAUDE_CODE_USE_OPENAI=1

# Your API key (or token)
set OPENAI_API_KEY=YourTokenHere

# Base URL for the OpenAI-compatible API endpoint
set OPENAI_BASE_URL=https://api.deepseek.com/v1

# Model name to use
set OPENAI_MODEL=deepseek-chat

Then run OpenClaude with a prompt:

npx cc-haha "Hello"

This will send "Hello" to the configured model and display the response.

Interactive Modes

OpenClaude offers several interactive modes:

Text-based User Interface (TUI)

Launch the interactive TUI interface:

npx cc-haha --tui

Combine with YOLO mode to skip initial prompts and enter TUI immediately:

npx cc-haha --dangerously-skip-permissions --tui

YOLO Mode

YOLO mode (--dangerously-skip-permissions or --approval-mode yolo) automatically approves all actions without prompting. This is useful for automation or when you fully trust the model's decisions.

Example usage:

# YOLO mode with a prompt
npx cc-haha "Hello" --dangerously-skip-permissions

# YOLO mode with TUI (skips startup questions)
npx cc-haha --dangerously-skip-permissions --tui

Warning: YOLO mode bypasses security checks. Use with caution.
