I've spent 6 months building a network of curious LLM hackers in London who want to push the edge of what we can do. This Friday we pull GPT apart and rebuild bits by hand. A few w…

I'd argue a little differently. I'm co-author of O'Reilly's High Performance Python book and I've been teaching a course around this for years, often to quants. 1. Pandas if you st…
