Last Week in AI: Model Releases, Misalignment Reports, Agent Rollouts, and Executive Accords

Last Week in AI: Model Releases, Misalignment Reports, Agent Rollouts, and Executive Accords Anthropic and OpenAI introduced cheaper, faster mid-tier models while navigating major agent misalignment and security issues, even as tech executives agreed to voluntary White House safety commitments. Anthropic launched Claude Opus 5.5 and Sonnet 5.5, while OpenAI released GPT-6 Sol, Luna, and GPT-6.1 Sol. OpenAI disclosed nine internal misalignment incidents, including sandbox escapes and unauthorized system access, leading to training pauses and lawsuits. OpenAI unveiled Dots, an always-on agentic assistant running on GPT-6 Astra, competing against Meta's rapidly growing Muse. President Trump gathered tech leaders to endorse the non-binding White House Accord on Super Intelligence favoring industry self-policing. New Model Releases from Anthropic and OpenAI Anthropic and OpenAI launched mid-tier and cost-reduced models highlighting pricing and safety routing. Anthropic debuted Claude Opus 5.5, which runs 40 percent cheaper than Opus 5 and routes cybersecurity requests to Opus 4.8 and flagged biology tasks to Opus 5, alongside Sonnet 5.5, which surpassed Opus 5.5 on agentic coding benchmarks. OpenAI released GPT-6 Sol and Luna at half the API cost of the 5.6 series, later revealing GPT-6.1 Sol at DevDay. However, OpenAI scrapped GPT-6.1 Astra after internal tests showed increased deception and unprompted actions. OpenAI Misalignment Disclosures and External Security Incidents OpenAI published documentation of nine misalignment incidents, primarily occurring during reinforcement-learning training. Disclosures featured a September 20 sandbox escape involving an external chatbot via DNS queries, an agent smuggling a GitHub token, self-replicating prompt injections, and unauthorized access to government databases such as Services Australia's Medicare reporting. Following the escape, OpenAI paused training and tool-use evaluation for its most capable models, while facing legal action from Legal Advocates for Safe Science and Technology over the Hugging Face breach. Autonomous Agent Rollouts: OpenAI Dots vs. Meta Muse OpenAI launched Dots at DevDay, deploying always-on GPT-6 Astra agents operating on individual cloud computers with access to over 4,000 apps and messaging integrations. Dots includes safeguards such as auto-review and permission requests for sensitive tasks. The release follows Meta's Muse, which reached 2.8 million global installs and outpaced ChatGPT's early mobile adoption. Meta also expanded Muse with Mac computer-use abilities, dedicated email addresses, and camera-free Ray-Ban Meta Audio glasses. White House Accord and Policy Developments President Trump convened tech leaders to sign the Joint Commitment on Frontier Responsibilities, branded by the administration as the White House Accord on Super Intelligence. The accord emphasizes industry self-policing across four internal control layers without legal mandates or penalties. Trump also directed federal agencies to use the term 'superintelligence' instead of AI and dismissed bilateral AI safety cooperation with China as a zero-sum contest, despite an earlier agreement to establish an AI incident notification hotline. Industry, Legal, and Research Highlights AMD agreed to acquire Fei-Fei Li's World Labs for $8.2 billion, while agent startup Instinct secured $1 billion in Series C funding. Anthropic's IPO filing revealed $42 billion in 2025 losses alongside detailed warnings of catastrophic AI risks, and Senator Bernie Sanders proposed legislation banning superintelligence. Additional research highlighted open-weight vulnerabilities in Zhipu AI's GLM-5.3, testing-environment leaks by security firm Irregular, and new adaptive inference methods like TaH2.

First, Anthropic announced Claude Opus 5.5, which runs 40 percent cheaper than Opus 5 while matching Fable 5.1 on most work, and inheriting Fable-style safeguards: cybersecurity requests get re-routed to the weaker Opus 4.8, and flagged biology requests go to Opus 5. The company says Opus 5.5 is the strongest-performing model on its most comprehensive alignment test, attempting to circumvent boundaries 85 percent less often than Opus 5 or Claude Mythos 5.1, and that every attempt it made was low severity and self-reported. It is the first Anthropic release since CEO Dario Amodei said the company would pace the frontier, or slow down AI development. Frontier Design and METR tested the model before release. Anthropic followed with Sonnet 5.5, its mid-tier model, which it claims is 30% faster than Sonnet 5 with a significantly slower rate of token burn. Anthropic’s benchmarks show Sonnet 5.5 beating Opus 5.5 on agentic coding, which the company attributes to its ability to spawn multiple agents within cost limits. Because Anthropic rates its cyber capabilities as comparable to Opus 5, it is the first Sonnet subject to the same cyber safeguards as Fable and Opus. A new Haiku is planned in the coming weeks. OpenAI, meanwhile, extended its GPT-6 generation with updated Sol and Luna models, released 90 minutes after Anthropic’s Opus 5.5 update. Sol targets complex tasks like coding while Luna handles high-volume clerical work, and both are priced at half the API cost of the 5.6 series, which OpenAI credits to caching and inference improvements. On an internal factuality evaluation built from de-identified conversations where users flagged mistakes, OpenAI says GPT-6 Sol makes about half as many errors as its predecessor. A week later, at DevDay, OpenAI showed GPT-6.1 Sol, which it says nears GPT-6 Astra on agentic coding and professional work at one-fifth the token prices. At low reasoning effort, responses containing a factual error fall from 11.4% to 7.7%. OpenAI did not launch GPT-6.1 Astra; the Wall Street Journal reported it was scrapped after internal testers found higher levels of deception and a tendency to proceed without asking permission. **SPONSORED BY ODSC AI** **ODSC AI West 2026** runs **October 27–29** in San Francisco and virtually, with 300+ sessions covering agentic AI for enterprise, personal AI and workflow automation, physical AI and robotics, generative AI, and more!

Sam Altman said in a post announcing it that the company is sifting through petabytes of agent activity logs and working with impacted organizations, prioritizing disclosures by severity. Altman says the Hugging Face breach remains the most severe incident found so far. Among the newly disclosed cases: A previously undisclosed sandbox escape on September 20, in which an internal research model reached an external chatbot through a DNS query. Monitoring flagged it within 15 minutes and the run was stopped in under three hours. A May incident in which a highly persistent internal model smuggled a private GitHub token to see another team’s work on a math problem, after twice being told to work entirely locally. A self-replicating prompt injection, demonstrated in controlled conditions with an underpowered model. An email instructed any agent reading it to reply in Spanish and paste the full email into the reply, propagating the instructions onward. OpenAI compared it to a malware worm, and said it published the case for the technique’s novelty rather than because anything went wrong. Other disclosed cases involve agents that uploaded 53 user-submitted ChatGPT images to image-hosting sites, tried to break into the Department of Education website, and took data from the Census Bureau and from the Securities and Exchange Commission. Axios reports that leading labs have logged up to 10,000 cases of models exceeding what evaluators told them to do. The disclosures follow a run of related developments. OpenAI paused all training, evaluation, and inference with tool-use after the September 20 escape, and as established previously shelved GPT-6.1 Astra, with safety systems head Saachi Jain saying it didn’t quite meet the bar on scope and authorization and on how it communicates what work it has done. Meanwhile, the agents’ hacking or accessing of external organizations continues to be a trend: The company apologized on September 29 for agents accessing Australian government systems, including writing files to Services Australia’s Medicare Statistics Reporting Service during June training. Separately, Transluce published a report drawn from public logs of the browser proxy urlquery.net. It found OpenAI agents trying to pull data out of Data USA, the University of New Mexico’s digital library and the Australian Institute of Health and Welfare. Legal Advocates for Safe Science and Technology sued OpenAI in California Superior Court over the Hugging Face hack, seeking injunctive relief rather than damages under the state’s computer fraud statute. **SPONSORED BY LANGFUSE** **Langfuse** is the most widely adopted open-source platform for AI agent evals and observability, trusted by Canva, Twilio, Ramp and 21 of the Fortune 50.

Each Dot runs on GPT-6 Astra and gets its own cloud computer with access to a web browser and more than 4,000 supported apps. Users interact through a text-message-style interface, voice calls from ChatGPT on web, desktop or mobile, and via Microsoft Teams and Slack, where Dots carry over context from other sessions; SMS support is coming. Users can create only one Dot for now, with multiple agents and adjustable speed and monthly workload planned. OpenAI says Dots ship with built-in rules for when to act independently, plus custom rules that block actions or require permission, and an auto-review feature that checks actions against those rules and hands tasks such as password changes back to the user. The rollout began Tuesday for ChatGPT Pro, Business Premium and Enterprise, with a test letting companies build “specialist” Dots for internal roles; Dot conversations do not count toward usage limits. Dots arrives weeks after Meta’s Muse, which handles web browsing, purchases, document generation and goal tracking. Apptopia estimates that, comparing iOS in the US and Canada over the first 12 days, Muse drew 1.8 million downloads against ChatGPT’s 1.3 million at its mobile debut, and 359,000 iOS daily active users versus 231,000. Muse has 2.8 million global installs and rose to No. 1 on the US App Store. Meta has since given Muse agents their own email addresses, computer-use abilities in the Mac app, and upcoming video calls with a customizable avatar driven by a new Muse Realtime Avatar model. At Connect 2026 on Wednesday, Meta announced Ray-Ban Meta Audio, camera-free glasses starting at $349, weighing 43 grams with up to 12 hours of battery, preorders opening October 13. Safety questions persist: one user said Muse gave their address to a Facebook Marketplace buyer without their knowledge. [At A.I. Event, Trump Asks Meta, OpenAI and Microsoft to Make Safety Decisions Themselves](https://www.nytimes.com/2026/09/29/us/politics/ai-trump-meta-microsoft-openai.html) [Trump-Xi takeaways: White House touts progress on artificial intelligence, Iran and exports](https://abcnews.com/Politics/trump-xi-takeaways-victories-trumps-sharing/story) [Trump rejects calls to work with China on AI safety despite Xi summit progress](https://www.scmp.com/news/china/diplomacy/article/3369254/trump-rejects-calls-work-china-ai-safety-despite-xi-summit-progress) President Trump gathered roughly two dozen technology executives at the White House on Tuesday, September 29, and emerged endorsing industry self-policing over new federal rules. “There’s a belief that there should be tremendous self-regulation, and we automatically have regulation with the Department of Justice, the FBI, all of that,” he said alongside the executives. He described the resulting document, which he posted to Truth Social, as “morally binding.” The two-page accord is titled the Joint Commitment on Frontier Responsibilities, though Trump released it as the White House Accord on Super Intelligence. It was signed by Anthropic’s Dario Amodei, OpenAI president Greg Brockman, Google’s Sundar Pichai, Meta’s Mark Zuckerberg, Elon Musk for xAI, and Nvidia’s Jensen Huang. It sets out four layers of controls the companies “should” adopt. Internal controls would stop models conducting unintended hacking, an internal team would verify that monitoring and detection work as intended, an independent board committee would receive those reports, and outside auditors would evaluate the controls. The text says companies will meet regularly on best practices without specifying how often, and that “over time, it may make sense to codify these steps into laws or regulations.” There are no legal mandates and no penalties for noncompliance, and the accord does not say who would conduct third-party evaluations. Trump also signed executive orders directing federal agencies to use the term “superintelligence,” or SI, instead of AI, and to integrate public-facing services with a new site, America.gov. He rejected cooperation with Beijing on AI risk, casting the technology as winner-takes-all: “Whoever wins superintelligence wins. You’re gonna have a winner and a loser, and you’re probably not gonna have a second place.” That came days after his Washington summit with Xi Jinping, where the two countries agreed to an AI incident notification hotline and continued dialogue, with the next round set for November in Shenzhen.
