Jeff Dean Leaves Google After 27 Years to Launch Discovery Loop

Alongside longtime collaborators Sanjay Ghemawat, Oriol Vinyals, and Quoc Le, the legendary engineer founds a public benefit corporation to automate machine learning research. Sundar Pichai calls him "incomparable."

Tomorrow will be my last day at Google after 27 years, watching it grow from 25 people to over 190,000. It has been an amazing journey. Now, alongside my longtime friends and collaborators Sanjay Ghemawat, Oriol Vinyals, and Quoc Le, we are founding Discovery Loop, a Public Benefit Corporation whose mission is to automate machine learning research itself. The announcement drew 12,896 likes and reached over 2 million views, underscoring Dean's legendary status in the AI community.

In a coordinated announcement, Sundar Pichai revealed that Demis Hassabis will step up to become Chair of Google DeepMind and Chief Scientist of Alphabet, while continuing to lead Isomorphic Labs. Andrew Ng congratulated Dean and team, saying "Knowing you guys, this will be amazing. Cheering you on and wishing you well on your important work." The restructuring marks one of the most significant personnel shifts in AI history, with Jeff Dean departing the company he helped build from a 25-person startup to a 190,000-employee giant.

Meta Ships Muse Code Beta, a Terminal Agent for Long-Horizon Software Engineering

Built on the new Muse Spark 1.2 model, Muse Code plans, implements, and validates complex multi-file changes across large repositories with persistent sub-agents.

Muse Code enters beta as Meta's first coding agent from MSL, built on Muse Spark 1.2. The terminal-based agent tackles complete software engineering tasks across large repositories, using persistent sub-agents for long-horizon planning and validation. Installable via curl, the release was amplified by Alexandr Wang, Yann LeCun, and other industry figures. The Artificial Analysis benchmark rates Muse Spark 1.2 at a score of 54, marking Meta's third model release in four months. Pricing comparisons suggest the contributor tier is dramatically cheaper than the baseline.

The Community Lit the Fire: MiniMax H3 Open Weights Spark 48-Hour Explosion

Open weights plus community equals possibility. In 48 hours, H3 went from release to the open-source community running it everywhere — ComfyUI, OpenRouter, Magnific, and Pika all jumped in.

MiniMax-H3, the SOTA open-weights video model, triggered a community frenzy within 48 hours of release. Pika brought H3 to its API Club at up to 50% less than other aggregators. ComfyUI integrated it directly. Early testers reported the model handling game-use shots, stop-motion aesthetics, and photoreal character swaps with surprising competence. "None of this was us," wrote Ryan Lee of MiniMax. "Day 1 and the first 48 hours belonged to the open-source community." The sentiment from Hailuo AI captured the mood: "Open weights set the spark, but the community builds the fire."

Clément Delangue: Google Could Have Dominated AI by Opening Up

The Hugging Face CEO argued that Google could have been the dominating force in AI by open-sourcing Gemini, Veo, and Nano Banana instead of keeping them behind APIs "for a few billion dollars in revenue." The post, which garnered 481 likes and 33,000 views, resonated with the open-source community's sentiment around Google's trajectory. "Maybe there's still time," he added pointedly.

Chime Used Runway to Produce a National TV Spot — Saved 85%

Chime transformed ~100 real member photos into a broadcast-ready national TV commercial using Runway, reducing production costs from $300,000 to under $30,000 — an 85% savings. The case study is being shared as a benchmark for AI-driven creative production at commercial scale.
