"How is LLaMa.cpp possible?" great post by @finbarrtimbers llama.cpp surprised many people (myself included) with how quickly you can run large LLMs on small computers, e.g. 7B runs @ ~16 tok/s on a MacBook. Wait don't you need supercomputers to work…

Watching a lot more Korean TV/content recently (Netflix and such) and finding it very refreshing compared to US equivalents. People are so much nicer, more courteous, respectful with each other, it’s beautiful and calming.

most common neural net mistakes: 1) you didn't try to overfit a single batch first. 2) you forgot to toggle train/eval mode for the net. 3) you forgot to .zero_grad() (in pytorch) before .backward(). 4) you passed softmaxed outputs to a loss that expects raw logits. ; others? :)

Random note on k-Nearest Neighbor lookups on embeddings: in my experience much better results can be obtained by training SVMs instead. Not too widely known. Short example: Works because SVM ranking considers the unique aspects of your query w.r.t. data.

A few new CUDA hacker friends joined the effort and now llm.c is only 2X slower than PyTorch (fp32, forward pass) compared to 4 days ago, when it was at 4.2X slower 📈 The biggest improvements were: - turn on TF32 (NVIDIA TensorFLoat-32) instead of FP32 for matmuls. This is a…

A file I wrote today is 80% Python and 20% English. I don't mean comments - the script intersperses python code with "prompt code" calls to GPT API. Still haven't quite gotten over how funny that looks.

Nice read on reverse engineering of GitHub Copilot 🪄. Copilot has dramatically accelerated my coding, it's hard to imagine going back to "manual coding". Still learning to use it but it already writes ~80% of my code, ~80% accuracy. I don't even really code, I prompt. & edit.

A while back I'd done some shallow reverse engineering of Copilot Now I've done a deeper dive into Copilot's internals, built a tool to explore its code, and wrote a blog answering specific questions and pointing out some tidbits. Do read, might be fun!

I think this is mostly right. - LLMs created a whole new layer of abstraction and profession. - I've so far called this role "Prompt Engineer" but agree it is misleading. It's not just prompting alone, there's a lot of glue code/infra around it. Maybe "AI Engineer" is ~usable,…
