Google Colab
What it is
Google Colab is a browser-based environment for writing and running Python without configuring a local setup. It provides access to GPUs, and its hosted Jupyter notebooks combine executable code with rich text, images, HTML, and LaTeX. Users can share notebooks and bring in data from Google Drive, spreadsheets, GitHub, and other sources; listed resources also include Google Cloud Storage, Sheets, and BigQuery. Colab AI can create or revise code, explain Python libraries, suggest fixes, and run multi-step data analysis workflows. By default, it does not access Drive files or user secrets, though it can generate code to access them when explicitly asked. Google says generative AI features may involve collection of prompts, related code, outputs, usage information, and feedback; human reviewers may process this data, which may be retained for up to 18 months. A free plan is available, with paid plans from $8.33/user/mo (annual). Free notebook sessions can run for at most 12 hours depending on availability and usage; Pro+ supports continuous execution up to 24 hours if sufficient compute units are available.
