GPUs Go Brrr (via) Fascinating, detailed low-level notes on how to get the most out of NVIDIA's H100 GPUs (currently selling for around $40,000 a piece) from the research team at Stanford who created FlashAttention, among other things.
The swizzled memory layouts are flat-out incorrectly documented, which took considerable time for us to figure out.
GPUs on Fly.io are available to everyone! We’ve been experimenting with GPUs on Fly for a few months for Datasette Cloud. They’re well documented and quite easy to use—any example Python code you find that uses NVIDIA CUDA stuff generally Just Works. Most interestingly of all, Fly GPUs can scale to zero—so while they cost $2.50/hr for a A100 40G (VRAM) and $3.50/hr for a A100 80G you can configure them to stop running when the machine runs out of things to do.
We’ve successfully used them to run Whisper and to experiment with running various Llama 2 LLMs as well.
To look forward to: “We are working on getting some lower-cost A10 GPUs in the next few weeks”.

A Hackers’ Guide to Language Models. Jeremy Howard’s new 1.5 hour YouTube introduction to language models looks like a really useful place to catch up if you’re an experienced Python programmer looking to start experimenting with LLMs. He covers what they are and how they work, then shows how to build against the OpenAI API, build a Code Interpreter clone using OpenAI functions, run models from Hugging Face on your own machine (with NVIDIA cards or on a Mac) and finishes with a demo of fine-tuning a Llama 2 model to perform text-to-SQL using an open dataset.
