Excited to share our work on envisioning Intelligent AI Delegation (arxiv.org/abs/2602.11865). Delegation in most existing AI systems is brittle, and relies on simplified hand-crafted control flows. As such, it fails to meet the requirements of what is needed to truly scale distributed reasoning and task completion in multi-agent systems and collectives.

When millions of AI agents interact with each other, new collective behaviors can emerge. 🌐 Together with @schmidtsciences, @coop_ai, @ARIA_research and supported by @GoogleOrg, we’re launching a $10M research fund to help understand how AI systems behave as a group. → goo.gle/3Si6rCl

I’m very excited that this is out. We’re looking forward to funding some great research
Over the past few months I've been working on a very exciting project: a new $10m fund for research on multi-agent multi-principal AGI safety! Instead of focusing on single agent alignment and centralized control, we're looking to support research focusing on multi-agent settings, mechanism design, cooperative AI, and coordination problems. This is a joint initiative between @GoogleDeepMind, @Googleorg, @schmidtsciences, @coop_ai, and @ARIA_research. Huge thanks to @James_D_Fox, @weballergy, @FranklinMatija, @lrhammond, and @ObadiaAlex for their invaluable work! See: deepmind.google/blog/investi… Apply: schmidtsciences.smapply.io/p…

We’re teaming up @Palmeiras, the first football club to meaningfully build upon TacticAI: our AI system that can help simulate field scenarios and predict open play dynamics up to 8 seconds in advance. ⚽

Congrats @sebkrier @weballergy @FranklinMatija @lrhammond! Oversight systems that help comps and govs oversee millions of AI agents from different labs are going to be hugely important and won't (and shouldn't be) be build by any of the big labs.

I am excited to announce this funding call, in collaboration with @schmidtsciences, @coop_ai @ARIA_research and @Googleorg As we are thinking about moving beyond individual powerful AI agents towards large-scale agentic collectives that can communicate and coordinate towards completing long-horizon complex tasks - it is paramount to design these future agentic societies safely.
With @schmidtsciences, @coop_ai, @ARIA_research and @GoogleOrg, we’re launching a $10M research fund to help understand how AI systems behave as a group and to fund work in multi-agent safety. We invite researchers to submit proposals in four priority areas: 1. Sandboxes and testbeds 2. The science of agent networks 3. Strengthening agent infrastructure 4. Oversight and control A big thank you to everyone that was involved including @James_D_Fox, @sebkrier, @weballergy, @lrhammond, and @ObadiaAlex!

Check out my team mates' work on using AlphaEvolve to discover novel cognitive models of learning! This is such an important stepping stone towards building tools that help human scientists gain more insights from their data. We certainly did!

AI agents are advancing research-level math. šŸš€ I’m thrilled to share @GoogleDeepMind’s AlphaProof Nexus - an agentic framework for formal proof search powered by Gemini. When applied to a set of open formal math problems, our agent autonomously solved: āœ… 9 open Erdős problems (including two open for 56 years!) āœ… 44 Online Encyclopedia of Integer Sequences (OEIS) problems āœ… A 15-year-old open problem in algebraic geometry āœ… A 7-year-old open question in min-max optimization We are collaborating with mathematicians across disciplines - from combinatorics and graph theory to quantum optics. Ultimately, these results show the massive potential of even simple agentic loops powered by Gemini. Read the paper here: arxiv.org/abs/2605.22763v1

Your RL post-training may be sabotaging your LLM’s test-time scaling! Conventional RL pretends that you can collapse all reward signals *upfront* into a single *scalar reward*. We introduce Vector Policy Optimization (VPO), which natively maximizes *vector-valued* rewards, boosting test time search performance, even on the original scalar.

Some new results I found surprising that I’m tweeting for Chris (who isnt on here). With enough compute, the best data filter for LMs (on DCLM) might be no filter. Why? Large models can tolerate a surprising amount of nominally 'low quality' data, and can sometimes even benefit.

Really happy to see @OpenAI adopt @GoogleDeepMind's SynthID for watermarking AI generated images. We need more such cross industry partnerships for enabling responsible use of AI systems.
May 19
We’re adding new ways for people to identify AI-generated images and understand where they came from. In addition to C2PA Content Credentials, images now also contain a SynthID watermark, and can be identified using a public verification tool to check whether an image was made by OpenAI products. openai.com/index/advancing-c…
