Spent a lot of MATS 10.0 doing SDF for "teaching Claude why" style stuff and stumbled onto a really cool trick for updating model beliefs with SDF. Models stay way more coherent, and you only have to train once for all your post-trained checkpoints. Check it out!!

New research led by @PeterNutter1 @DJROYTBURG via @MATSprogram: a better way to update model beliefs that we call grafting.

Fine-tune the base model with next-token prediction on synthetic documents (SDF), and simply apply the weight update onto the post-trained model. This works!

Excited to share my first paper, and it's an ICML 2026 oral!

We wrote up the main takeaways in a blog post (below). If you'll be at ICML, find us at:

Oral: Tue Jul 7, 1:30 PM KST, Hall D2
Poster: Wed Jul 8, 10:30 AM KST, Hall A #3213

See you there!

Excited that our ICML position paper has been accepted as an Oral 🎉!

When a model looks like it "deceives" or "resists shutdown," how do we know it isn't role-play, instruction-following, or just task-completion pressure? Often the current evidence can't yet tell them apart, and those claims are starting to inform deployment and regulation.

We map where the evidence gets thin across four stages and propose a shared standard to strengthen it. Here's the map.
