Battle-test AI coding models side by side
Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
Watch models construct web apps and websites live, so you can see process and output, not just the final file.
Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
Track which coding models accumulate the most wins over time to identify consistently strong performers.
Free courses, live events and community for building real AI skills
Curated course paths for knowledge workers on applying AI at work, developers building with Codex and the OpenAI API, leaders planning AI adoption, and educators bringing AI into the classroom.
A rolling calendar of in-person workshops, livestream sessions and past recordings, covering topics from ChatGPT basics for government staff to advanced Codex automation.
Community spaces connect learners with peers and practitioners working on similar AI problems, so best practices spread beyond the course materials.
Short features show how individuals, nonprofits and businesses use AI in practice, giving concrete examples rather than abstract theory.
Delivers rigorous professional AI engineering courses and certifications by Andrew Ng, but lacks OpenAI's official product focus.
