We applied the same data-driven approach that led to SOTA English performance in๐ท FineWeb to thousands of languages.
๐ฅ FineWeb2 has 8TB of compressed text data and outperforms other multilingual datasets in our experiments.
The dataset is released under the permissive ๐ ODC-By 1.0 license, and the ๐ป code to reproduce it and our evaluations is public.
We will very soon announce a big community project, and are working on a ๐ blogpost walking you through the entire dataset creation process. Stay tuned!
- Pre-training code with nanotron - Evaluation suite with lighteval - Synthetic data generation using distilabel (powers our new SFT dataset HuggingFaceTB/smoltalk) - Post-training scripts with TRL & the alignment handbook - On-device tools with llama.cpp for summarization, rewriting & agents
Apache 2.0 licensed. V2 pre-training data mix coming soon!
๐ท FineWeb technical report is out and so is ๐ FineWeb-Edu, a 1.3 trillion tokens dataset that outperforms all other open web datasets, with remarkable improvements on educational benchmarksย such as MMLU, ARC, and OpenBookQA.
We used Llama 3 generations to train an educational quality classifier, filtering the 15 trillion tokens of FineWeb to select only those with high educational value (an approach also used in Llama 3 and Phi-3 training datasets). We're releasing both FineWeb-Edu and the classifier, along with a larger, less heavily filtered version containing 5.4 trillion tokens.
You can find more details about the dataset and the experiments we ran in the FineWeb technical report, It's a 45-minute read but it contains all the secret sauce for building high quality web datasets.
[New crazy blog post alert] We are releasing an extensive blog post on the science of creating high quality web-scale datasets, detailing all the steps and learnings that came in our recent 15 trillion tokens ๐ทFineWeb release
Inspired by the distill.pub interactive graphics papers, we settled to write the most extensive, enjoyable and in-depth tech report we could draft on so prepare for a 45-mmin read with interactive graphics and all.
And it's not all, in this article we also introduce ๐FineWeb-Edu a filtered subset of Common Crawl with 1.3T tokens containing only web pages with very high educational content. Up to our knowledge, FineWeb-Edu out-performs all openly release web-scale datasets by a significant margin on knowledge- and reasoning-intensive benchmarks like MMLU, ARC, and OpenBookQA
We also make a number of surprising observations on the "quality" of the internet it-self which may challenge some of the general assumptions on web data (not saying more, I'll let you draw your conclusions ;)
Is is time for the open-source AI robots revolution ๐?
With @haixuantao and @Leyo weโve been playing with a low-cost DJI robot controlled by three local open-source AI models (Whisper, Idefics2, Parler-TTS - all Apache2) and orchestrated by Dora-cs.
Very interesting model just released by MyShell: jetmoe/jetmoe-8b . It's a 8B-parameters MoE LLM so 2.2B active parameters, really efficient.
Main characteristics: - impressive performances for its size (beating meta-llama/Llama-2-7b and huggyllama/llama-13b) - combine Mixture of Attention heads (MoA) and Mixture of MLP Experts (MoE) โ 8 experts with 2 being active for each token - trained on a rather limited 1.25T tokens from publicly available datasets โ training recipe follows the MiniCPM's two-phases training method => first time I see this for a 2B+ model - $100k to train - open weights - open sharing of recipes - open dataset - open code => โก - still interesting room to improve performances (be it only by training longer)
Note: I actually detailed all of the MiniCPM schedule, Mixture-of-expert (MoE) and many of the datasets used in this work in my recent little guide to building LLMs in 2024, so feel free to check it out if you want to learn more on these topics: https://www.youtube.com/watch?v=2-SPH9hIKT8
