> Demis Hassabis steps down as Google DeepMind CEO to become GDM Chair and Alphabet Chief Scientist; Koray Kavukcuoglu takes day-to-day SVP; Jeff Dean leaves after 27 years to found public-benefit Discovery Loop with Sanjay Ghemawat and, per wires, Oriol Vinyals and Quoc Le. Not a product ship — a control-plane rewrite for one of the three frontier labs.

This is not a product ship — it is a **control-plane rewrite** for one of the three frontier labs. Day-to-day model execution moves to Kavukcuoglu; Hassabis becomes strategic AGI/science face; Dean’s generation of infrastructure DNA leaves for a Google-backed but **independent** science PBC.

**Google** restructured **Google DeepMind** leadership. **Demis Hassabis** leaves day-to-day GDM CEO duties to become **Chair of Google DeepMind** and **Chief Scientist of Alphabet**, while continuing to lead **Isomorphic Labs**. **Koray Kavukcuoglu** (GDM CTO / Chief AI Architect) becomes **SVP of Google DeepMind**, reporting to **Sundar Pichai**. Separately, **Jeff Dean** ends a **27-year** Google run to co-found **Discovery Loop**, an independent **public benefit corporation**, with **Sanjay Ghemawat** and — per multi-outlet reporting — **Oriol Vinyals** and **Quoc Le**. Google will be a **founding investor** and **Cloud partner**.

## Leadership map

| Person | Old | New |
|--------|-----|-----|
| **Demis Hassabis** | CEO, Google DeepMind | **Chair, GDM** + **Chief Scientist, Alphabet**; keeps **Isomorphic Labs** |
| **Koray Kavukcuoglu** | CTO GDM / Chief AI Architect | **SVP, Google DeepMind** (Gemini models, frontier research, Gemini app & developer teams) |
| **Jeff Dean** | Google Chief Scientist | **Leaves**; CEO path at **Discovery Loop** (PBC) |
| **Sanjay Ghemawat** | Google Senior Fellow | Co-founder, Discovery Loop |
| **Oriol Vinyals / Quoc Le** | Senior AI leaders (secondary wires) | Departing with Dean cohort (Reuters / WSJ) |

Primary source of truth: [Sundar Pichai + Demis Hassabis blog post](https://blog.google/company-news/inside-google/message-ceo/next-chapter-ai-momentum/) on Google’s Keyword blog.

## What Google said it is optimizing for

Pichai’s memo pairs two pressures: **accelerate the full AI stack** (Search, YouTube, Cloud, Gemini products) and free Hassabis to **shape AGI and science** externally and strategically. Product color in the memo: Gemini app at **950M+** monthly users; **Gemma** past **900M+** downloads; Flash demand and a live **Cyber** model called out as momentum markers. Hassabis’s note says AGI feels “close at hand,” cites confidence in **Gemini 4** progress under Koray’s model leadership, and doubles down on **Isomorphic** / health as AI’s #1 application.

## Discovery Loop

Google’s primary post names Dean + Ghemawat launching an independent PBC to accelerate discoveries in **ML, science, and engineering**, with Google as founding investor and Cloud partner plus collaboration on an ML-systems research framework. Secondary reporting (Axios, Reuters, WSJ, NYT) adds co-founders **Vinyals** and **Le** and frames the exit as one of the largest simultaneous talent moves out of Google AI infrastructure and research leadership in years.

## Limits

- Vinyals/Le co-founder detail is secondary-wire, not named in Google’s primary post the same way as Dean/Ghemawat.
- Gemini 4 timing and Discovery Loop’s first public surface are not in this announcement.
- Whether Gemini release cadence holds under Kavukcuoglu is the open execution question.
