We are releasing an expanded version of Global PIQA! It now covers 141 language varieties and includes parallel and non-parallel splits. We are also releasing an updated preprint.

Very very excited that Global PIQA is out! This was an incredible effort by 300+ researchers from 65 countries. The resulting dataset is a high-quality, participatory, and culturally-specific benchmark for over 100 languages.

Did you know? ❌77% of language models on @hf.co are not tagged for any language 📈For 95% of languages, most models are multilingual 🚨88% of models with tags are trained on English In a new blog post, @tylerachang.bsky.social and I dig into these trends and why they matter! 👇

With six weeks left before the deadline, we have had over 50 volunteers sign up to contribute for over 30 languages. If you don’t see your language represented on the map, this is your sign to get involved!

We scaled training data attribution (TDA) methods ~1000x to find influential pretraining examples for thousands of queries in an 8B-parameter LLM over the entire 160B-token C4 corpus! medium.com/people-ai-re...

The Goldfish models were trained on byte-premium-scaled dataset sizes, such that if a language needs more bytes to encode a given amount of information, we scaled up the dataset according the byte premium. Read about how we (@tylerachang.bsky.social) trained the models: arxiv.org/pdf/2408.10441
