About Cog
Cog is an open-source tool that packages machine learning models into standard, production-ready containers. It eliminates the complexity of Docker and environment configuration by automatically generating container images from a simple configuration file. Cog ensures reproducibility and consistency across development and production environments, making ML model deployment straightforward for data scientists and engineers alike.
- Containerized ML Models: Automatically builds Docker containers for your ML models without requiring Docker expertise.
- Simple Configuration: Define your model's environment in a single
cog.yamlfile specifying Python version, dependencies, and GPU requirements. - Standard HTTP API: Cog automatically generates a standard HTTP prediction API for your model, ready for deployment.
- GPU Support: Seamlessly handles CUDA and GPU dependencies, ensuring your model runs correctly on GPU-enabled hardware.
- Reproducible Environments: Pins all dependencies and system packages so your model runs the same way everywhere.
- Open Source: Freely available under an open-source license on GitHub, with community contributions welcome.
To get started, install Cog via the CLI, create a cog.yaml configuration file in your project directory, define your predictor class in Python, and run cog build to generate a container image. The resulting image can be run locally or deployed to any container-compatible cloud platform.
