AIMistral models now power Firefox Smart Window, Mozilla's AI browsing assistant in beta. Mistral will serve users in France and North America first, with the United Kingdom and Germany expected later this year. Conversations are not saved on Mozilla's servers by default, and partners such as Mistral agree to zero data retention.

AIJeff Dean congratulated Periodic Labs on results from its materials-science AI work. The post itself provides no specific figures, so the announcement is limited to the congratulations.

AIFei-Fei Li announced that World Labs is recruiting robot learning researchers and engineers. A follow-up post from Yunzhu Li says the team aims to define and scale next-generation world models for robot learning.

AIOpenAI will retire GPT-5.5 in ChatGPT, ChatGPT Work, and Codex on October 14 across all plans. Codex users who rely on GPT-5.5 are advised to switch to GPT-5.6 Sol or GPT-6 Astra.

AIDelphi, which turns experts' knowledge into digital minds, runs its Python backend on Vercel with a 10-person team and no dedicated infrastructure role. The stack uses Vercel Workflows for long-running agents and Vercel Queues for background jobs. The team reports more than 100 production deploys a day.

AIPeriodic Labs, the team behind high-throughput materials labs in Menlo Park, reports progress on one of condensed matter physics' hardest problems. Its open-source model Neon, trained with mid-training and RL on 1,300 H200s plus months of lab data, surpasses GPT-6 Astra on the company's analysis benchmark. The work targets materials science challenges including superconductors, magnets, and semiconductors.

AIGreg Brockman says OpenAI's Astra and Luna are taking off. A quoted post reports that Astra led last week's spending while Luna led by a wide margin in token usage, compared with Anthropic.

AIVarun Mohan says Gemini 3.8 Flash on Antigravity is under high load, causing some requests to fail. The team is actively fixing the issue and plans to reset rate limits once it is resolved.

AICognition and AWS have entered a multi-year Strategic Collaboration Agreement to help enterprises deploy the Devin autonomous engineer in production. Devin can be purchased through AWS Marketplace, and the companies are exploring deeper engineering integrations within customers' AWS environments. Mercedes-Benz reportedly used Devin to analyze more than 200,000 lines of COBOL, reducing an estimated eight-month modernization project to eight days.

Why it matters: The collaboration shows how an autonomous coding agent is being packaged for enterprise legacy modernization inside existing AWS environments, with concrete customer migration figures.

AIPeriodic Labs chose SGLang and Miles to build Neon, an open-source model it says surpasses GPT-6 Astra on its analysis benchmark after mid-training and RL on 1,300 H200s. RadixArk says Periodic extended both frameworks for scientific RL at trillion-parameter scale, delivering more efficient training, lower memory use, and 2.5x faster inference. The work has been contributed back to both projects.

AILangChain is using Baseten Loops, a managed fine-tuning service, to train custom models for LangSmith Engine, its in-platform agent that debugs and improves AI agents. The article says LangChain fine-tunes large open-weight models on agent traces and trains smaller open-weight models such as Qwen for tasks like failure-mode categorization. Baseten Loops supports supervised fine-tuning, reinforcement learning, and long-context workloads, and lets checkpoints be evaluated and deployed directly to inference.

AIAir Street Capital led Jack & Jill's $40 million Series A, with Madrona joining and Creandum and Entrepreneurs First investing again, following a $20 million seed round less than a year earlier. Jack & Jill uses AI agents named Jack, which helps candidates plan career moves and search job postings, and Jill, which helps companies recruit from opted-in candidates. The company says it has arranged 25,000 interviews and plans 5,000 more each month.

AIWaymo has signed a formal agreement with Nihon Kotsu and GO to start operating autonomous taxis in Tokyo in 2027. The post links to a Waymo blog post with further details about the Tokyo launch.

AIFactory has raised $200M at a $5B valuation from investors including Blackstone, Khosla Ventures, and Sequoia Capital, bringing its total funding to over $400 million. The company says it will use the capital to accelerate research, product, and global go-to-market efforts. Factory says hundreds of thousands of developers use its platform, with customers including Nvidia, Blackstone, and T-Mobile.

AIWaymo is partnering with Allianz Partners to build insurance, claims, and safety research infrastructure for its planned autonomous ride-hailing expansion in Europe, starting with London and Munich. The collaboration will provide tailored fleet insurance, liability protection, and digital claims handling, plus joint crash analysis and safety modeling research. Waymo cites a 16x reduction in serious injury crashes compared to human drivers in cities where it operates.

AIOlivia's parents used ChatGPT to prepare questions for her doctors, who identified a rare genetic disorder and later found abnormal brain activity. With treatment, she is sick less often and now sleeps through the night.

AIFast Company named Google the winner of its 2026 Innovation by Design Awards for its holistic design vision and new AI design language. The language spans products including the Gemini app, Google Maps' Immersive Navigation, and Search AI Mode. Josh Woodward, who runs Google's Gemini app, invited readers to design with the team.

AIMira Murati said Thinking Machines is building machine intelligence to expand human will and judgment, and welcomed Neil Chowdhury to help make that future safe. Chowdhury, who joined Thinking Machines to work on safety and alignment, said he wants safety systems that let control over AI be shared widely rather than concentrated in a few hands.

AIJohn Schulman publicly welcomed Neil Chowdhury, who joined Thinking Machines to work on safety and alignment. Chowdhury's background post says he wants to build safety systems that let control over powerful AI be shared widely rather than concentrated in a few hands.

AIThe Hailuo AI Bestiary contest closes tonight, September 14 at 23:59 PT, with $8,000 cash, 200,000 Credits, and ten Audience Choice awards. Entrants must submit a 30-second-or-longer short film generated with MiniMax H3 on any myth, era, or world.

AIWaymo, Nihon Kotsu and GO have agreed to prepare a commercial, fully autonomous ride-hailing service in Tokyo, targeting first public rides in 2027. The service will be available through the GO and Waymo apps, starting with an initial fleet and expanding to around 100 vehicles across key Tokyo neighborhoods. The launch depends on regulatory approval from national and local authorities and completion of ongoing validation.

AISatya Nadella says Quincy, Washington shows what datacenters can achieve when built alongside local communities and expanded over time. The post is a brief remark, with no figures or specific commitments stated in the text provided.

AITencent Hunyuan posted that much more AI is coming, with no specific model, date, or feature named. The post follows an Ivan Fioravanti visit to Tencent's Beijing headquarters, where he praised the team and said Hy4 Preview is only the tip of the iceberg.

AIOracle co-CEO Mike Sicilia argued on the Q1 FY 2027 earnings call that AI accelerates rather than replaces packaged applications, and promised an "agentic AI accelerator" in October to compress SaaS deployments from years to months. Oracle's SaaS revenue grew 10 percent, while software license revenue fell 3 percent to $5.5 billion and cloud revenue rose 60 percent to $11.6 billion. The company also said GPUs coming up for renewal were renewed or resold at a 20 percent premium and that it turned on 850 MW of new datacenter capacity in the quarter.

AILaravel announced last week that it no longer accepts GitHub issues and requires contributors to submit pull requests instead. The article argues that PR-only policies filter out spam issues and help maintainers, since users can now generate PRs with AI.
