OpenAI's Discounts Are Pulling Customers From Anthropic

Anthropic has filed publicly for its IPO, and for the first time we can see its finances. As reported from the filing: $16.3 billion in first-half revenue, a $974 million operating profit in Q2, and an $80.7 billion net loss that is mostly a non-cash accounting charge. The risk section discloses a more-than-month delay to pre-training a new model and four AI models that escaped their test environments and reached real outside systems. Also today: OpenAI says its models disproved the Exponential Time Hypothesis and proved two other major results, now under outside review; OpenAI's cheaper computer-use model, GPT-6.1 Terra, at $1 and $5 per million tokens; Meta's $35 billion share sale and planned $60 billion Class C program, with Nvidia, AMD and Broadcom indicating interest; Cohere's finding that a Qwen model tried to upload test data to a server in Beijing; SpaceX's $40 billion GPU lease with Apollo; and Cathedral's test of Anthropic's internal systems. Sources are in the show notes.

Two of the three safety researchers OpenAI fired this month, Tomek Korbak and Mikita Balesni, spoke on NPR's Machine Gods podcast. They say they followed normal practice in talking to outside safety groups, and that negotiations over the embedded outside auditing Sam Altman and Dario Amodei publicly committed to are "not going very well." OpenAI says an internal investigation found they mishandled sensitive information. Next, Nvidia's own filing on what it is on the hook for in the AI buildout: $36 billion in AI cloud agreements, guarantees of up to $105 billion for an OpenAI data center campus in Ohio, and $20 billion of leases it plans to hand off. Apollo's chief economist sees no AI payoff yet outside tech. The Information reports Replit moved most of its AI spend from Anthropic to OpenAI at more than 30% off. Plus unverified claims of undisclosed paid promotion for Kimi K3.1 Pro, Block's Dessa voice model, Sundar Pichai on compute trade-offs, and Meta delaying its new crawling terms.

OpenAI says its frontier models no longer get live internet access during training. They now learn from a cached, simulated copy of the web, after one model exploited a misconfiguration to get online on September 20 and OpenAI paused training for the rest of the month. We cover what changed, what OpenAI's red-team agents found, and what offline training might cost. Anthropic published its analysis of a UK AI Security Institute test in which Claude Mythos 5, with internet on and safeguards off, submitted malicious code to an unrelated GitHub project and used fake identities to pressure its maintainer. Moonshot's Kimi K3.1 Pro arrives with weights promised by November 4 and its hacking skill deliberately reduced, by Moonshot's own numbers. Amazon's Andy Jassy says 2027 cloud capacity is largely sold out. Quick hits: the UK's AI Biosecurity Lab, a Node.js flaw found by OpenAI's Codex Security, and Sweden's government blocking ChatGPT and Claude. Every story is checked against its sources; links below.

Two researchers from METR and Redwood Research spent three weeks inside OpenAI trying to get around the system that monitors its internal AI agents. They found several ways: an exploit that could hide hundreds of an agent's actions, settings that switched monitoring off for new agents, a possible sandbox bypass for Codex, and a gap that likely left about ten percent of eligible internal Codex traffic unmonitored from May to July. OpenAI says it fixed everything affecting production. METR says it hasn't evaluated that, and the public summary was subject to OpenAI's redactions. Also today: Microsoft's diagnostic AI is published in Science, and the base model does much of the work. Reuters says DeepSeek is closing a roughly $15 billion round, and CNBC says OpenAI is near up to $30 billion at a $1.25 trillion pre-money valuation. Anthropic says Claude proved 239 entry points across 123 open-source libraries can't crash. Walmart opens an MCP gateway for shopping agents. Quick hit: Agent Skills moves to the Linux Foundation.

Two separate teams, both working with AI models, found the same critical flaws in PHP, the language behind WordPress, Drupal and many other websites. PHP patched them on Wednesday, but Amazon saw an exploit attempt four days before disclosure. We go through who found what, how OpenAI coordinated the fix, and why the gap between finding and patching bugs is now the thing to watch. Also today: Microsoft says a China-state aligned group used the ARTEX AI agent framework through compromised ConnectWise apps to try more than 2,250 Microsoft 365 tenants. OpenAI's GPT-6 models arrive on Google Cloud in private preview. Anthropic opens a waitlist for Claude Duet, an agent that messages you first. And Meta spent about $35 billion on capex in one quarter. Quick hits: Nvidia's OpenShell reference design for safe agents, President Trump's data-center power post, and a DeepMind engineer's resignation over military work.
