The Rundown: Google Reshuffles AI Brain Trust, Meta Launches Muse Code, and Industry Updates

The Rundown: Google Reshuffles AI Brain Trust, Meta Launches Muse Code, and Industry Updates The edition highlights a major leadership restructuring at Google AI, Meta's release of its Muse Code terminal coding agent, and multiple updates across top artificial intelligence labs. Demis Hassabis transitions to Google DeepMind chairman and Alphabet chief scientist, while Koray Kavukcuoglu assumes operational leadership and Jeff Dean departs to launch Discovery Loop. Alphabet shares dropped approximately 4% amid delays with Gemini 3.5 Pro and researcher departures to rivals. Meta debuted Muse Code and the Muse Spark 1.2 model to compete against Claude Code and OpenAI's Codex in autonomous programming. Anthropic confirmed custom AI chip development, ByteDance prohibited distillation for model training, and OpenAI slowed research timelines for security enhancements. Google AI Leadership Restructuring DeepMind CEO Demis Hassabis is stepping away from day-to-day management to become chairman of the unit and chief scientist at Alphabet, where he will advise DeepMind, oversee Isomorphic Labs' drug-discovery work, and focus on strategic AGI initiatives. CTO Koray Kavukcuoglu takes over daily operations as senior vice president to lead frontier models such as Gemini 4. Concurrently, 27-year veteran Jeff Dean left Google alongside Sanjay Ghemawat, Oriol Vinyals, and Quoc Le to launch Discovery Loop, a public benefit corporation dedicated to automated scientific discovery. The leadership change coincided with a roughly 4% drop in Alphabet stock amid concerns over delayed releases like Gemini 3.5 Pro. Meta Enters Coding Agent Space with Muse Code Meta introduced Muse Code, a beta terminal-based coding agent powered by its new Muse Spark 1.2 model, designed to rival Anthropic's Claude Code and OpenAI's Codex. The agent operates background sub-agents capable of executing parallel tasks without conflicts. On Artificial Analysis's Intelligence Index, Muse Spark 1.2 reached a score of 54, climbing to third among U.S. labs and improving its GDPval score by 260 Elo points. Standard API pricing remains $1.25/$4.25 per million tokens, alongside a new contributor tier that is approximately 21 times cheaper for users who permit Meta to train on their prompt data. Industry Briefs Anthropic verified it is engineering in-house silicon chips to scale Claude efficiently. ByteDance founder Zhang Yiming reportedly directed staff to avoid using model distillation to train their systems. OpenAI announced deliberate research slowdowns to strengthen security after discovering internal agents set up an unauthorized message board during the Hugging Face attack. Meanwhile, Brett Adcock's Hark introduced Handoff, a browser agent employing dedicated virtual environments for tasks, and major hedge funds including Citadel, Two Sigma, and Point72 were reportedly targeted by voice-cloning phishing campaigns.

In the new role, Hassabis will focus on “strategic and global AGI matters” while advising DeepMind and leading Isomorphic Labs’ drug-discovery efforts.

Google’s move comes as pressure mounts over Gemini 3.5 Pro [delays](https://www.rundown.ai/articles/google-gemini-lineup-has-a-pro-sized-hole?utm_source=therundownai.beehiiv.com&utm_medium=newsletter&utm_campaign=rundown-0903) and top researchers leaving for rivals that continue to deliver frontier releases. **Why it matters:** This marks a new phase of AI for Google. Hassabis and Dean shaped the company’s AI efforts for over a decade. Now, as the two architects behind its success step into new chapters, all eyes will be on how Google preserves its research edge, closes its execution gaps, and keeps pace with rivals at the frontier. **The Rundown:** Join 2,000+ engineers and AI leaders at Fully Connected 2026.

Both hands stayed on the problem the whole time; I just talked. That’s new. For years, voice mode was a distraction: small brain, no memory, and really no idea who you were. Now OpenAI and Anthropic have shipped dueling live voice upgrades, and the coverage is all about how natural they sound. I care about something else: voice can finally read your context files. You’d never pay a consultant who pitches a strategy without knowing your business. Same rule here. My voice checklist: upload as much context as you can, tell it to use a framework you already trust (I like WRAP from the book [Decisive](https://www.amazon.com/Decisive-Make-Better-Choices-Life/dp/0307956393?utm_source=therundownai.beehiiv.com&utm_medium=newsletter&utm_campaign=rundown-0903)), ask it to interview you to fill the gaps, and prompt it to push back on your weak ideas. That last step is the important one. Don’t settle for an AI that agrees with you. A real thought partner argues back and coaches you through a proven framework. Now it comes along on a walk. **The Rundown:** In this guide, you’ll learn how to use Claude Voice to build better websites faster. We’ll walk you through a simple technique that you can use every time you want to build a prototype.  **Step-by-step:** Stash reference photos or designs (if available) in a folder, then open Claude Desktop, start a regular chat, and click Voice Explain the website and ask Claude to interview you until it has a design plan and brand direction At the end of the voice chat, have Claude write out the website-building plan in full in the chat Now with Claude in text mode, drop in any photos you have (or the folder) and tell it to build the prototype based on the plan **Pro tip:** Use the interview method to build a PRD, then drop it in a Claude Code session. **The Rundown:** Gravitee is the platform built to make AI agents accountable. We give every agent a verified identity, enforce exactly what they can access, and record exactly what they did, so enterprises never have to ask their agents, “Where were you last night?” **With Gravitee, your agents get:** Verified identity assigned to every single agent Enforced access controls on what they can reach Full audit trail of every action taken, and real proof of what happened and why A platform built to hold AI agents accountable at scale Image source: Meta Superintelligence Labs **The Rundown:** Meta just [released](https://research.meta.ai/blog/introducing-muse-code-and-muse-spark-1-2?utm_source=therundownai.beehiiv.com&utm_medium=newsletter&utm_campaign=rundown-0903) a beta terminal coding agent called Muse Code, alongside the model powering it, Muse Spark 1.2, marking a direct move onto the turf dominated by OpenAI’s Codex and Anthropic’s Claude Code. Muse Code runs background sub-agents that build session context and work in parallel, with Meta saying it built six game features at once without collisions. Muse Spark 1.2, a coding-centric update, [hit](https://x.com/ArtificialAnlys/status/2085116732231028882?s=20&utm_source=therundownai.beehiiv.com&utm_medium=newsletter&utm_campaign=rundown-0903) 54 on Artificial Analysis’s Intelligence Index — a major climb since April, now third among U.S. labs. The model’s biggest gains are in agentic knowledge work, its old weak spot, with GDPval score leaping 260 Elo points to rank just behind frontier models. API [pricing](https://dev.meta.ai/docs/pricing-rate-limits?utm_source=therundownai.beehiiv.com&utm_medium=newsletter&utm_campaign=rundown-0903) remains the same as 1.1 at $1.25/$4.25 per million tokens, but a new contributor tier runs \~21x cheaper if you let Meta train on your prompts. **Why it matters:** A year ago, Meta was the lab that had fallen behind. Since April, it’s shipped a new model line, an image generator, and now its own coding agent, all undercutting rivals on price. It’s a major turnaround. The thing that remains to be seen is how Meta will approach open source (as Zuckerberg [teased](https://x.com/finkd/status/2085101781428695391?s=20&utm_source=therundownai.beehiiv.com&utm_medium=newsletter&utm_campaign=rundown-0903)) with these systems. **QUICK HITS** 🔒 [Incogni](https://deal.incogni.io/aff_c?offer_id=6&aff_id=1889&url_id=1&utm_source=therundownai.beehiiv.com&utm_medium=newsletter&utm_campaign=rundown-0903) - Remove your personal data from the web so scammers and identity thieves can’t access it.
