Generate intelligent Git commit messages with AI. Supports Conventional Commits, emoji, and multiple LLM providers like OpenAI, Ollama, and Gemini.

🤔 What is Commity?

Commity is an open-source, AI-powered Git commit message generation tool. It analyzes your staged code changes and automatically generates commit messages that follow the Conventional Commits specification, and can even add emojis for you!

With a simple commity --emoji command, you can get a professional and clear commit message like this:

feat(api): ✨ add user authentication endpoint

🔧 Installation

Install with pip:

pip install commity

Or install with uv:

uv tool install commity

⚙️ Configuration

commity supports three configuration methods, with the following priority: Command-line Arguments > Environment Variables > Configuration File.

Supported model providers are: Gemini (default), Ollama, OpenAI, OpenRouter, NVIDIA.

Gemini, OpenAI, OpenRouter, and NVIDIA always require an API key. Commity aborts early if those keys are missing so you get fast feedback before hitting the network.

✨ Method 1: Specify Model Parameters via Command-line

OpenAI

commity --provider openai --model gpt-3.5-turbo --api_key <your-api-key>

Ollama

commity --provider ollama --model llama2 --base_url http://localhost:11434

Gemini

commity --provider gemini --model gemini-2.5-flash --base_url https://generativelanguage.googleapis.com --api_key <your-api-key> --timeout 30

or

commity \
--provider gemini \
--model gemini-2.5-flash \
--base_url https://generativelanguage.googleapis.com \
--api_key <your-api-key> \
--timeout 30 \

OpenRouter

commity --provider openrouter --model openai/gpt-3.5-turbo --api_key <your-openrouter-api-key>

or

commity \
--provider openrouter \
--model anthropic/claude-3.5-sonnet \
--api_key <your-openrouter-api-key> \

NVIDIA

commity --provider nvidia --model nvidia/llama-3.1-70b-instruct --api_key <your-nvidia-api-key>

or

commity \
--provider nvidia \
--model nvidia/llama-3.1-nemotron-70b-instruct \
--api_key <your-nvidia-api-key> \

🌱 Method 2: Set Environment Variables as Defaults

You can add the following to your .bashrc, .zshrc, or .env file:

OpenAI

export COMMITY_PROVIDER=openai
export COMMITY_MODEL=gpt-3.5-turbo
export COMMITY_API_KEY=your-api-key

Ollama

export COMMITY_PROVIDER=ollama
export COMMITY_MODEL=llama2
export COMMITY_BASE_URL=http://localhost:11434

Gemini

export COMMITY_PROVIDER=gemini
export COMMITY_MODEL=gemini-2.5-flash
export COMMITY_BASE_URL=https://generativelanguage.googleapis.com
export COMMITY_API_KEY=your-api-key
export COMMITY_TEMPERATURE=0.5

OpenRouter

export COMMITY_PROVIDER=openrouter
export COMMITY_MODEL=openai/gpt-3.5-turbo
export COMMITY_API_KEY=your-openrouter-api-key
export COMMITY_TEMPERATURE=0.5

NVIDIA

export COMMITY_PROVIDER=nvidia
export COMMITY_MODEL=nvidia/llama-3.1-70b-instruct
export COMMITY_API_KEY=your-nvidia-api-key
export COMMITY_TEMPERATURE=0.5

📝 Method 3: Use a Configuration File (Recommended)

For easier configuration management, you can create a ~/.commity/config.json file in your user's home directory.

1. Create the directory:

   mkdir -p ~/.commity
   

2. Create and edit the config.json file:

   touch ~/.commity/config.json
   

3. Add your configuration to config.json, for example:

   {
     "PROVIDER": "ollama",
     "MODEL": "llama3",
     "BASE_URL": "http://localhost:11434"
   }
   

   Or using Gemini:

   {
     "PROVIDER": "gemini",
     "MODEL": "gemini-1.5-flash",
     "BASE_URL": "https://generativelanguage.googleapis.com",
     "API_KEY": "your-gemini-api-key"
   }
   

   Or using OpenAI:

   {
     "PROVIDER": "openai",
     "MODEL": "gpt-3.5-turbo",
     "API_KEY": "your-openai-api-key"
   }
   

   Or using OpenRouter:

   {
     "PROVIDER": "openrouter",
     "MODEL": "openai/gpt-3.5-turbo",
     "API_KEY": "your-openrouter-api-key"
   }
   

   Or using NVIDIA:

   {
     "PROVIDER": "nvidia",
     "MODEL": "nvidia/llama-3.1-70b-instruct",
     "API_KEY": "your-nvidia-api-key"
   }
