Shopify teams are using AI to announce their internal tools is one of the most delightful side effects of the AI age. This one is too fun not to share

Training LLMs end to end is hard. Very excited to share our new blog (book?) that cover the full pipeline: pre-training, post-training and infra. 200+ pages of what worked, what didn’t, and how to make it run reliably huggingface.co/spaces/Hugging…

Please steal my AI research ideas. This is a list of research questions and concrete experiments I would love to see done, but don't have bandwidth to get to. If you are looking to break into AI research (e.g. as an undergraduate, or a software engineer in industry), these are…

New blog post: The bug that taught me more about PyTorch than years of using it started with a simple training loss plateau... ended up digging through optimizer states, memory layouts, kernel dispatch, and finally understanding how PyTorch works!

one of the often overlooked factors behind deepseek’s success lies in how the team built their distributed infrastructure from the ground up (despite severe gpu constraints!). their custom communication library hfreduce replaced nccl and delivered substantially higher bandwidth…

You know how if you spend the whole day sitting on the couch watching TV, you get kind of restless yet somehow also too tired to get off your butt? Like you're tired *of* doing nothing, yet you're also tired *from* doing nothing? You know what I'm talking about, the state of…

I have fine-tuned over 100 different LLMs/VLMs for various use cases over the last 1–2 years, and here is my framework whenever I pick a new project or problem statement: 1. Benchmark/Evals Any problem you are solving for should have an evaluation set that you can easily…

What should I name this plugin?

can this be an extension in vscode, it just freezes your vscode randomly and plays phonk

Last night I taught nanochat d32 how to count 'r' in strawberry (or similar variations). I thought this would be a good/fun example of how to add capabilities to nanochat and I wrote up a full guide here: github.com/karpathy/nanoc… This is done via a new synthetic task…
