Google released an updated iteration of their Deep Research tool that uses the new 2.5 Pro model. This was taken from a post originally made on Twitter, so please excuse the terseness.

First impressions:

So yeah, these tools are getting good! Kudos to the teams who are implementing this stuff. Hard to make it perform reproducibly well on so many open-ended uses. But more work to be done!

IMO the really great implementations of this ‘deep research’ pattern will all be in-house where you can have control over:

A few other things:

The other thing that I think we’re really going to need to work on is research taste. Like the LLMs that power them, GDR and OpenAI DR offer a level of research taste developed to the mean. (I know people are thinking about this since it came up on Dwarkesh’s podcast with the AI 2027 guys, but they were focused on scientific research.)

I think there’s not a single answer for this which is, again, why I see the end result as people bringing these things in-house where they get to develop and refine what makes their particular flavour of research unique. (In the human-generated research world this is very much the case, where certain institutions (or even particular authors) are known for how deep they go, or what kinds of sources they prefer, or how they choose to feature or highlight the primary sources they access, and so on.) There are many possible variations of how this manifest, and I hope that we’re headed into a world where all the AI ‘deep researchers’ will be unique and quirky in all the best senses of that word.
