    It was great to see @thinkymachines LoRA w/o Regret blog, which connects nicely to our work on Tina (LoRA for RL). For wider use, we’re releasing a clean implementation of RL with LoRA, DoRA, QLoRA/QDoRA, plus speedups & more, across models from 1.5B–32B. Nice work @UpupWang!

    We now know that LoRA can match full-parameter RL training (from x.com/thinkymachines… and our Tina paper arxiv.org/abs/2504.15777), but what about DoRA, QLoRA, and more? We are releasing a clean LoRA-for-RL repo to explore them all. github.com/shangshang-wan…

    An awesome set of resources on LLM reasoning and test-time compute, compiled by @UpUpWang — check it out!

    🔍 Diving deep into LLM reasoning? From OpenAI's o-series to DeepSeek R1, from post-training to test-time compute — we break it down into structured spreadsheets. 🧵

    Excited to release METAGENE-1, a 7B parameter metagenomic foundation model, built to aid in pathogen detection & pandemic monitoring. Pretrained on 1.5 trillion base pairs of DNA/RNA sequenced from wastewater. A collab w/ @USC, @PrimeIntellect, & the Nucleic Acid Observatory. 🧵

    Benchmarking multimodal ​foundation models via isomorphic prompts (different data modalities, same information)​ — great work led by @DeqingFu, @ghazalkhn, and @olliezliu​!

    Do multimodal foundation models treat every modality equally? Hint: Humans have picture superiority. How about machines? Introducing IsoBench, a benchmark for multimodal models with isomorphic inputs. 🔗 IsoBench.github.io

    Excited to share that I will join @USC as an Asst. Professor of Computer Science in Jan 2024—and I’m recruiting students for my new lab! 📣 Come work at the intersection of machine learning, decision making, generative AI, and AI-for-science. More info: willieneis.github.io/lab
