Leandro von Werra @lvwerra.bsky.social · 06/01/2025Distributed training is notoriously hard to learn - knowledge is scattered across papers and complex codebases. Enter picotron: implementing all 4D parallelism concepts in separate, readable files totaling just 1988 LoC! 240

Reposted by Leandro von WerraAnton @anton-l.bsky.social · 19/12/2024Introducing 📐FineMath: the best open math pre-training dataset with 50B+ tokens! Math remains challenging for LLMs and by training on FineMath we see considerable gains over other math datasets, especially on GSM8K and MATH. 🤗 huggingface.co/datasets/Hug... Here’s a breakdown 🧵 24615
Leandro von Werra @lvwerra.bsky.social · 19/12/2024Releasing Jupyter Agents - LLMs running data analysis directly in a notebook! The agent can load data, execute code, plot results and following your guidance and ideas! A very natural way to collaborate with an LLM over data and it's just scratching the surface of what's possible soon! 1144

We applied the same data-driven approach that led to SOTA English performance in🍷 FineWeb to thousands of languages. 🥂 FineWeb2 has 8TB of compressed text data and outperforms other datasets. 17619
Reposted by Leandro von WerraThomas Wolf @thomwolf.bsky.social · 08/12/2024The FineWeb team is happy to finally release "FineWeb2" 🥂🥳 FineWeb 2 extends the data driven approach to pre-training dataset design that was introduced in FineWeb 1 to now covers 1893 languages/scripts Details: huggingface.co/datasets/Hug... A detailed open-science tech report is coming soon 310613
Leandro von Werra @lvwerra.bsky.social · 28/11/2024There are not many opportunities out there to build open LLMs and make them state-of-the-art, too! This is one of them. 0161
Reposted by Leandro von WerraXenova @xenova.bsky.social · 27/11/2024WOW! 🤯 Language models are becoming smaller and more capable than ever! Here's SmolLM2 running 100% locally in-browser w/ WebGPU on a 6-year-old GPU. Just look at that speed! ⚡️😍 Powered by 🤗 Transformers.js and ONNX Runtime Web! How many tokens/second do you get? Let me know! 👇 24610
Leandro von Werra @lvwerra.bsky.social · 26/11/2024Some people are pushing models to the top right of the plot following the scaling laws, others push them to the top left and make them faster and cheaper! We need both! 1111
Reposted by Leandro von WerraAnton @anton-l.bsky.social · 25/11/2024Check out how easy it is to do LLM evals with LightEval! * any dataset on the 🤗 Hub can become an eval task in a few lines of code: customize the prompt, metrics, parsing, few-shots, everything! * model- and data-parallel inference * auto batching with the new vLLM backend 27610
Reposted by Leandro von WerraThomas Wolf @thomwolf.bsky.social · 24/11/2024It's Sunday morning so taking a minute for a nerdy thread (on math, tokenizers and LLMs) of the work of our intern Garreth By adding a few lines of code to the base Llama 3 tokenizer, he got a free boost in arithmetic performance 😮 [thread] 527134
Leandro von Werra @lvwerra.bsky.social · 21/11/2024What's the secret sauce of SmolLM2 to beat LLM titans like Llama3.2 and Qwen2.5? Unsurprisingly: data, data, data! The SmolTalk is open and available here: huggingface.co/datasets/Hug... 2627
Leandro von Werra @lvwerra.bsky.social · 19/11/2024All the things you need to know to pretrain an LLM at home*! Gave a workshop at Uni Bern: starts with scaling laws and goes to web scale data processing and finishes training with 4D parallelism and ZeRO. *assuming your home includes an H100 cluster 5779
