Hassabis's team has practised open science and open access with all of its scientific work.

Test: as of December 2024, had Google DeepMind (Hassabis's team, including the earlier DeepMind) made all of its scientific work available openly, meaning research published openly or open-access and key scientific outputs released for others to use? Judge the claim as stated, including the word 'all', but limited to scientific work, not commercial products such as Gemini. True: the evidence shows the team's scientific work (for example AlphaFold, AlphaFold DB, AlphaFold 3, GNoME, AlphaMissense, weather models) was consistently published openly, with code, models or data made available, and no notable scientific output was kept closed. Mostly true: open science was the clear and consistent practice, with only minor exceptions such as a delayed release or a narrow restriction. Mixed: a substantial share of the scientific work was open, but significant outputs were withheld or restricted. For example, AlphaFold 3 was first released without code and later with weights for academic use only, and some papers were published without code. Taken together, 'all' clearly overstates the practice, though it rests on real open releases. Mostly false: significant scientific work was kept closed and the openness was selective, so the claim overstates a partial practice. False: the evidence shows the team's scientific work was generally not published openly or not made accessible.

Set before the research began.

   “The initial publication, six months ago, of AlphaFold3 without its code drew criticisms from scientists, who said the move undermined reproducibility.”

4. E4 Report: Google’s DeepMind is withholding AI research for competitive advantage Sherwood News · 1 April 2025

   “the organization is breaking with that tradition of scientific sharing by withholding AI research for Google’s strategic advantage in a very competitive market.”

E1 (Nature) reports that AlphaFold3 was first published without its code, which scientists criticised as undermining reproducibility, and that it was made open source only later, in November 2024. E3, a journal piece dated February 2025 (after the claim) and known only by its headline, describes AlphaFold as one that "Drops Open Access". E2 shows the GNoME materials data was released, but only under a non-commercial licence. Taken together, the evidence shows real open releases but also significant outputs that were withheld or restricted, so the word 'all' overstates the practice; this matches the 'mixed' standard in the criteria.
