Free practical deep learning courses, research and open-source libraries
A free, top-down course that gets you training real models immediately and explains the theory as you go, with notebooks and video lessons.
A newer educational format that teaches iterative, exploration-driven problem solving with an interactive platform, replacing the classic course structure.
A high-level API that makes modern deep learning techniques concise and accessible while staying flexible for research work.
Develop, test, document and publish complete Python packages directly from Jupyter notebooks, ending the notebook-versus-git conflict.

Free LLM toolkit: cost calculators, prompts and model comparison
Estimate API costs for GPT-4, Claude, Gemini and 25+ models and compare pricing across providers before you spend.
Access a large library of ready-made prompts and count tokens for any model to reduce cost and improve efficiency.
Find the best model for a use case and compare MMLU, HumanEval and other performance metrics interactively.
Chat with several AI models at once for side-by-side comparison, and upload PDFs or Word files to query them with AI.
