Best AI/ML Operations for Open Source (2026)

The GitHub for machine learning models

Largest open source AI model repository. Host, share, and deploy models. Transformers library is the standard for NLP. Spaces for free model demos. Community-driven and increasingly the center of open AI development.

AI development platform for training and deployment

Platform for building, training, and deploying AI models. Built by the PyTorch Lightning team. Good for ML engineers who need managed infrastructure without the complexity of raw cloud providers.

Run ML models with a cloud API

Run open source ML models via API without managing infrastructure. Pay per prediction. Great for prototyping and production. Supports thousands of models. Low barrier to using AI without the devops overhead.

ML experiment tracking and model management

Track ML experiments, visualize results, manage models. The standard for ML experiment tracking. Used by OpenAI, DeepMind, and thousands of teams. Good free tier for individuals.
