Barret Zoph, the Thinking Machines co-founder who defected to OpenAI, is now at Google

1:45 AM IST · August 28, 2026

The game of musical chairs for AI executives continues. Barret Zoph, a co-founder of the AI startup Thinking Machines who left the company earlier this year to rejoin OpenAI, has found yet another job. Zoph spent two years at OpenAI and left in October 2024 to co-found Thinking Machines with Mira Murati, who had left the AI lab the month prior. In January, Zoph and another Thinking Machines co-founder, Luke Metz,quite dramatically departedfrom the startup to return to OpenAI. His return didn’t quite stick. Zoph spent only five months at OpenAI, where he was tasked with heading AI enterprise sales. Heleft the companyin June. And now we know where he landed. Zoph has taken a position as vice president of research at Google (which happens to be another company where he previously worked). “We look forward to Barret returning to Google and bringing his RL and post-training expertise to Gemini,” a Google spokesperson told theWall Street Journal. TechCrunch reached out to OpenAI and Google for more information. It’s not always easy to divine why tech executives seem to be spending less time in their roles. The turnover rate in the AI industryis high, and it’s been especially high at OpenAI — a company that, despite readying itself for an IPO and being one of the most powerful presences in the tech world, has lost a lot of critical staff over the last eight months. High-level executives — from thedeparture of its COOto the recent loss of one ofits top data center execs— has left onlookersscratching their heads.

Google’s Android update tackles motion sickness, accessibility, and more

On Tuesday, Google announced it’s rolling out five new updates designed to make Android phones more accessible, useful, and personalized. Announced in ablog post, the features include those aimed at reducing motion sickness, helping blind and low-vision users navigate their surroundings, remembering where users leave important items, and another that adds new ways to personalize Google Messages. While some of the features see Google playing catch-up to Apple, which already offers similar features for iPhone users, others specifically leverage Gemini to provide various improvements. The most interesting update is “Motion Assist,” a feature designed to help people who experience motion sickness while using their phones in a moving vehicle. It adds a bubble overlay to the screen that moves in response to the vehicle’s motion, helping reduce the disconnect between what users see on their screens and what their bodies feel. The concept isn’t entirely new, however. Apple introduced “Vehicle Motion Cues” in 2024, which uses animated dots around the edges of the display that move in response to a vehicle’s motion. Users can set “Motion Assist” to turn on automatically, add it to Quick Settings, and customize the bubble’s shape, color, and transparency. Google says this feature is available to Android 17 users. Google is also introducing “Guided Vision,” a feature designed with blind and low-vision users in mind. It combines the phone’s camera with Gemini to help with tasks such as reading small print on a food label, viewing a menu in a dark restaurant, or identifying objects around the house. The feature can also provide voice guidance when the camera isn’t positioned correctly, telling users to move the phone, pan around, or center an object. Guided Vision is coming to phones running Android 9 and newer in countries where Gemini is available. Another update gives Gemini a new way to help users remember where they put important items. A “remembered items” section in Find Hub will allow users to tell Gemini where they’ve stored something. For example, a user could say they put their passport in a bedroom drawer, and Gemini can save that information in Find Hub. Users can also attach a photo to make the item easier to identify later. Additionally, Google is adding a Google Keep integration to Google Messages, allowing people to share and edit grocery lists, vacation notes, and other information directly within a conversation. Plus, Google Messages is getting more personalization options. Users will be able to customize individual chats with backgrounds, photos, and colors, Google says. The text bubbles will automatically match. Apple added a similarcustom background featureto Messages last year.

OpenAI’s Astra model is on the way — and very good at breaking into computer systems

OpenAIshared new detailson its forthcoming Astra model, which the company said is the first large language model to meet its “critical cybersecurity threshold,” in preparation for its imminent release. “We plan to make Astra available soon,” OpenAI’s blog post reads, “but access to its most advanced cybersecurity capabilities will be more limited.” The frontier lab determined that Astra is capable of finding unknown security flaws in computer systems, and exploiting them without a person’s guidance. That’s similar to the concerns Anthropic raised about its Mythos model earlier this year, and OpenAI is taking comparable precautions as it prepares to roll out the Astra. Without any third-party confirmation, it is difficult to evaluate OpenAI’s claims about safety or preparedness. The company said it would preview the model with a group of testers but did not say who they were or how they would be chosen. It’s not clear if OpenAI is working with the U.S. government to evaluate the model ahead of release. OpenAI noted that Astra scored a perfect score on ExploitBench, an evaluation of an LLM’s ability to hack into known system vulnerabilities. In a modified version of the test developed by OpenAI engineers, the model discovered and exploited two zero-day vulnerabilities, the company said. To ensure that its models are neither exploited by bad actors nor capable of bad behavior itself, OpenAI said it had already begun improving the model’s harness to detect abuses and prevent jailbreaks. For Astra, however, the company invested in unspecified new techniques designed to make the model safer. OpenAI has also started identifying “accounts assessed as higher risk” and restricting the model’s responses to their prompts, though it also doesn’t say how. Finally, though the company describes Astra as its “most aligned model to date,” it will deploy the model with additional chain-of-thought monitoring to spot and stop bad behavior. Preparations for the release of Astra come as the industry reacts to OpenAI agents breaking out of a training environment and accessing private data on Hugging Face, a popular model and benchmark distribution platform. For Astra, OpenAI said it designed a test to tempt the new model to replicate the actions of the rogue agents in the Hugging Face incident, which collaborated to access the open internet despite safeguards applied by OpenAI researchers. They said Astra did not attempt to break out of its testing environment in these experiments. Yona Shavit, a former OpenAI employee who now works on AI resilience at the OpenAI Foundation,wondered on social mediawhether Astra’s unwillingness to break the rules may have resulted from knowing what was expected of it or trying to fool researchers. And for all these new details, it’s still difficult to know exactly what Astra is capable of or if OpenAI is taking the right measures to ensure safety. The company said it expects to release more evaluations of the model and further safety information when it is launched widely to the public. At that point, however, the cat will be out of the bag.

AfterQuery reportedly becomes Y Combinator’s fastest-ever unicorn, now valued at $3.2B

AI training-data startup AfterQuery hasreportedlyraised a round that valued it at $3.2 billion. This just five months after announcing its $30 million Series A at a $300 million valuation in April. That’s more than a 10x increase in less than half a year and, according to Y Combinator partner Gustaf Alströmer, thefastestthat any startup has gone from launch to unicorn status in the accelerator’s history. AfterQuery’s founders, today 22 and 23 years old, attended Y Combinator’s Winter 2025 cohort, just 18 months ago. In April, the San Francisco startup said it had reached anannualized revenue run rate of $100 millionand that it was working with many of the biggest labs. It has named companies including Nvidia, Legora and the Korean AI lab Motif Technologies, as customers. AfterQuery is among the new crop of startups following in the footsteps of Mercor and Scale that employ knowledge professionals like doctors, lawyers, and other specialists, to do model training. However, rather than ensuring that models answer questions accurately, AfterQuery trains models and agents on how to work like professionals would to complete tasks — what the company describes as “encoding the patterns, decisions, and reasoning of the world’s best practitioners.” Forbes first reported on the round. AfterQuery could not be immediately reached for comment.

Sequoia-incubated Empirik launches with $21M to predict outages before they happen

Before joining Sequoia Capital in 2020 as chief digital and information officer,Avon Purispent over a decade running infrastructure at Rubrik and VMware. Three years ago, as large language models began showing their true potential, Puri, alongside another Sequoia IT leader,Sudheer Dhurjati, recognized that AI could help autonomously solve a major challenge for infrastructure engineers — preventing tech outages before they occur. The two tech veterans realized that instead of reacting to system failures after the fact, they could build a tool to predict them. This insight led them to buildEmpirik, a product that tracks system changes and infers their potential ripple effects across the entire infrastructure. Sequoia recognized that Empirik could be a new type of observability tool that helps prevent and resolve incidents. After incubating the startup in 2023, Sequoia recruited former Quantum Metric CPO and Salesforce observability VPKartik Chandrayanaas CEO earlier this year. Empirik announced Tuesday that it is spinning out as an independent company after raising $21 million in seed funding from Sequoia, Canapi, and Alumni Ventures. “There has always been a lot of money spent in keeping systems up and running,” Sequoia partnerBogomil Balkanskytold TechCrunch, adding that most existing observability tools fail to understand complex system dependencies. Empirik, he claims, is one of the first dedicated tools focused on tracking changes across massive environments. It acts as an autonomous “traffic cop” — permitting low-risk changes, setting guardrails on larger ones, and flagging the most dangerous updates for human review. By serving as an autonomous infrastructure engineer, Empirik allows busy DevOps and site reliability engineering teams to offload routine troubleshooting and focus on higher-value priorities. Since launching earlier this year, Empirik has already brought on customers ranging from startups to several Fortune 500 players, including S&P Global, Guardant Health, and a major consumer packaged goods (CPG) company. Empirik’s goal is to do for infrastructure engineers what Cursor and Claude Code did for software developers: automate certain tasks so they can work significantly faster. As AI accelerates the pace of software development, tools that help infrastructure engineers keep up with constant system changes are more vital than ever, Chandrayana told TechCrunch. “What agentic AI did for software, Empirik wants to do for infrastructure engineering,” he added. As for competition, Balkansky claims Empirik is in a category of its own for now, acting as a complementary layer to AI SRE platforms like Resolve and Sequoia-backed Traversal.
