Summary
Google, Microsoft, and Amazon report significant growth in their cloud businesses, with Google Cloud revenue more than doubling to $30.7 billion, Microsoft Azure growing by 48%, and Amazon Web Services increasing by 39% to $46 billion. However, both Google and Amazon are experiencing negative free cash flow due to high capital expenditures, primarily driven by investments in AI. Google spent $51.4 billion on property and equipment, while Amazon's spending reached $77.3 billion, leading to a combined negative free cash flow of over $51 billion for the two companies. Microsoft, on the other hand, adjusted its spending forecast downward due to delays in AI chip deliveries, indicating a demand for AI remains strong despite supply chain constraints.
In the realm of AI advancements, Google introduces its strongest model, Gemini 4 Carbon, aimed at cybersecurity, but it is currently restricted to select cyber defenders. Anthropic showcases an unreleased model capable of exploiting vulnerabilities in widely used software, emphasizing the importance of scanning code for security. Meanwhile, Mistral releases the weights of a trillion-parameter model for sovereign AI applications, promoting its use on private hardware. Reports also surface about two Chinese labs utilizing outputs from OpenAI's models to train their own, raising concerns over the implications of distillation in AI development.
The podcast highlights a broader trend in the AI industry, where physical and financial limitations are becoming increasingly apparent. Delays in chip availability and negative cash flows are prompting companies to seek alternative funding methods, such as debt deals and share sales. Governments are also taking a more active role, with Canada investing in AI firms like Cohere, indicating a shift from mere regulation to active participation in the AI landscape. The future of AI development may hinge on how companies navigate these challenges and the terms under which powerful models are made accessible.
Show Notes
Alphabet, Microsoft and Amazon all reported this week, and the pattern is the same: cloud demand is accelerating, but the AI build-out is now consuming more cash than it produces. Google Cloud grew 103%, Azure 48%, AWS 39%. Alphabet's free cash flow was negative $9.1 billion for the quarter, Amazon's trailing-twelve-month free cash flow was negative $42.4 billion, and Microsoft reportedly trimmed its spending forecast because outside GPU capacity arrived late. Also today: Google's Gemini 4 Carbon, its strongest model, released first only to vetted cyber defenders; Anthropic's report that an unreleased Claude model built five exploit chains against Chrome, Safari, Android, Windows and Linux, all patched; Mistral's open-weight Mistral Large 4, about one trillion parameters, pitched for sovereign cyber defense; a report from The Information that DeepSeek and Moonshot trained on GPT-6 Astra outputs; OpenAI's expanded misalignment monitoring; a DOJ inquiry into Nvidia's Hugging Face deal; and Canada's equity stake in Cohere.

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.

Yesterday it was Replit. Now the same report from The Information, summarised by The Decoder, names more customers moving from Anthropic to OpenAI. Rippling's CEO says OpenAI's share of its coding work rose from 16% to 52%, while Anthropic's fell from 57% to 18%. DataCamp's CEO says OpenAI's pricing cut costs 80 to 90%. An investor memo says Anthropic's growth slowed from Q2 to Q3. We explain what's behind the "up to 90%" headlines and what it means for anyone buying AI at scale. Also: China's State Council issues guidance telling firms to pace AI in labour-intensive industries and explore an "unemployment buffer period"; Texas sues OpenAI and asks for a court-appointed evaluator to approve new models; a study finds Grok and GPT pick opposite parties in the midterms; Musk says lenders are shutting out neoclouds; the US-China AI blocs; agents that stop reporting problems; and Elvis Presley's rights holders sue Anthropic.

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.

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.
