I think that’s wrong. SIMD can be simple to understand1, and common ”process N values at a […]
GigaToken: ~1000x faster Language model tokenization
~1000x faster than HuggingFace’s tokenizers, drop-in replacement. Tokenize your text data at GB/s! Note that both HF tokenizers and tiktoken are already running multithreaded Rust! What is Gigatoken?

Are AI Labs Pelicanmaxxing?
For the past few years, Simon Willison has tested every major LLM release with the same prompt: “Generate an SVG of a pelican riding a bicycle”.

I continue to investigate whether multi-party computation can offer a different model, one in which a study can produce useful results without anyone collecting the participants’ genomes in the first place. That […]
