Jonathan Whitaker

Hello there! I’m Johno Whitaker - welcome to my personal website :)

About Me

I’m a Data Scientist/AI Researcher doing R&D with answer.ai. I like teaching and making courses. My current focus is on generative AI, flitting between several modalities.

This website is a central repository for everything I’m working on. You can find my blog posts, videos, TILs and just about everything else in the ‘Everything’ feed. If you’re looking for even more info, you may also want:
