Google's agents machine-checked proofs of 6 hard problems, then opened the tool to 10,000 researchers.

Verified: the post was read directly at research.google, and every number and quotation here comes from it. That establishes publication, not reproduction. No outside group has rerun the formalizations, and the Lean files were not located. The dated event that would move it: an independent recheck by June 30, 2027.

Vahab Mirrokni, Google Fellow and Vice President at Google Research, published "Advancing science and engineering with Antigravity's /teamwork" on research.google on November 13, 2026. The post reports results from /teamwork, a multi-agent feature in Antigravity, run with human experts across mathematics, chemistry, systems software and machine learning engineering. On the Courtade-Kumar conjecture, an information theory problem posed in 2013, it says Gemini 4 Argon and earlier Gemini models developed most of the new analytical bounds, and that "the team formalized the entire proof in Lean 4, producing 50 million lines of code." On the Weil conjectures it says /teamwork-LEAP fully autonomously produced an end-to-end machine-checked formalization: "This formalization spans about 1.8 million lines of Lean, produced across 28,800 subagent invocations." On Hilbert's tenth problem, "the system also synthesized over 919,000 lines of Lean to produce the first formalization" of a recent proof over general rings of integers. It reports the first formalization of the Birkhoff conjecture, a dynamical systems problem open since 1927, and of the 3D Bochner-Riesz conjecture, open more than 50 years, "finding and fixing a gap in a recently released informal proof along the way." It reports an independent reproduction of an end-to-end formalization of a recent proof of finite-time blowup for 3D Navier-Stokes with smooth forcing, which it describes as open for about 90 years. Further results are named on Tarjan's Deque Conjecture, Boolean matrix multiplication and integer multiplication. On peer review, "authors of 578 submissions (over a third of all submissions)" to STOC 2027 opted in to Deep Review; in an ongoing survey of 70 respondents, 90% rated the feedback mostly or almost all factual and 90% said they would use it again. Gemini 4 Argon is named as the main model, with Carbon and Hydrogen in the introduction. On access: /teamwork, /boost and Deep Review are available to external users now, Deep Review gives 2 free calls per user each week, and the team is "giving 10,000 academic researchers six months of free access to our highest usage tier" by application. Not established: compute cost, wall-clock time, how many of the 10,000 places get filled, eligibility, and whether anyone outside has rerun the work.

1. 1927 TO 2013

   The Birkhoff conjecture is posed in 1927, Bochner-Riesz in the 1970s, Courtade-Kumar in 2013. All stay open. Machine-checking a single hard proof takes a human team years.

2. Nov 11

   Google releases a DNA model that reads genes cell by cell, free for research. Edition 087's science card.

3. Nov 12

   Google releases Gemini 4 Hydrogen for coding and agent workflows. Edition 090's card. Antigravity is where those agents run.

4. Nov 13

   Google Research publishes the /teamwork results: 6 named problems, 1.8 million Lean lines on the Weil conjectures alone, a gap found in a recent informal proof, and 10,000 free academic seats.

   The same day a Helsinki logician tells the Guardian that Claude turned 1,009 pages of Godel's shorthand into 663 theorem candidates, about 400 of which checked out. Two laboratories, one week, formal mathematics.
