Interesting research, but I wish people would stick to the clearer term “inference-time computation” instead of the more ambiguous and confusing “test-time computation.”

Literally everything you do during inference is inference-time, no?

Well, if all you're doing is accessing stuff that was pre-learned earlier, then it's not quite inference-time.

OK, I like this. It’s an agent-based add on to (for now) Gemini that aims at improving the quality of output through a more ‘human’ style of research - digging deeper, considering counter examples, fleshing out with more research thin areas.

I’d like to try it, but I just learned I need and Enterprise Agentic subscription of some sort from Google; no idea how much that costs.

That said, this seems like a real abuse of the term diffusion, as far as I can tell. I don’t think this thing is reversing any entropy on any latent space.

They published a paper, and this isn't something complex that would take a lot of work to implement. You could probably give codex an example open source deep research project, then sic it on the paper and tell it to make a fork that uses this algorithm, I wouldn't be surprised if it could basically one shot implement.

Yeah good idea. Virtual Lucid Rains could reimplement.
