Can flow language models scale to billions of parameters and handle real generative tasks?

Introducing 🌊 Lafa (Large flow language model), a flow LM scaled up to 8B that matches AR quality, with 🚀 2.5× AR throughput at 7B.

Glad to have contributed to this project!

This year was a huge turning point in my research career. It started with building flow language models, and then I watched the whole field take off in just a few months.

Along the way, I got to meet and collaborate with so many amazing people across the dLM, bio, and flow communities, all working together to push continuous LMs forward.

I believe this survey is a nice way to close out the year when continuous LMs made their comeback, and a starting point for exciting new directions ahead. Can't wait to see what we all build next!

New survey on Continuous Diffusion and Flow Language Models is out! 🌊💬

One of my first papers, back in early 2025, was on continuous simplex flows. After working on discrete diffusion, I wanted to try controllable sequence generation with flow matching, which naturally operates in continuous spaces. But at the time, I found them much harder to train well than discrete diffusion. 🥲

2026 has changed this picture completely! 🚀 It’s been super exciting to watch continuous LMs take off, but with the rapid advancements, it’s also becoming harder to keep up with all the new work across pre-training, few-step generation, guidance, and scaling 🥹

So together with @chandavidlee, @FEijkelboom, and @jw9730, we put together a survey that consolidates the continuous LM literature and its key insights into 37 pages. It covers everything from the early work before the so-called “winter” of continuous LMs to the wave of new papers in 2026 🌟

More in thread! 🧵

I’m at #COLM2026 for presenting three FMLM papers at the NonAR-LM workshop— one as an oral presentation. Feel free to reach out in SF this week!
