Key Takeaways
- ChatGPT has reached 1.2 billion weekly active users, adding 200 million over the past two months, according to consumer product lead Adam Fry. Fry also said ChatGPT's search volume…
- OpenAI says its GPT-6 Astra model designed a hardware device for the Codex coding agent in under a week, handling enclosure, circuit board, and firmware. Several revision rounds we…
- Revolut says it cut AI coding inference costs by roughly 90% in less than a year by making self-hosted GLM models its default over commercial tools like Claude Code. The move highl…
- Fal: $1.3B (Unknown)
- CrowdStrike → Fiddler AI ($400M)
- Use a capable model to help triage incoming AI-assisted pull requests and identify the most useful fixes before reviewing them yourself.
Why Today Matters
- AI infrastructure economicsEnterprise AI economics are shifting from renting to owning: Revolut says self-hosted GLM models cut coding inference costs about 90%, while inference startup Fal raised $1.3 billion at a $16 billion valuation, suggesting infrastructure demand spans both cheap in-house deployment and well-funded external capacity.
- Agent securityAgent security is becoming a product category. CrowdStrike launched a Falcon Guardian AI kill switch and agreed to acquire Fiddler AI for about $400 million and Dreadnode for about $95 million, as companies reportedly deploy agents faster than security teams can establish controls.
- Benchmark durabilityAI capability claims are aging fast: Stanford researchers found 44% of 50 widely cited LLM claims already expired, with an average lifespan of 15.7 months, a caution worth applying to OpenAI's account that GPT-6 Astra designed hardware in under a week, which the company says needed revision rounds for manufacturing tolerances.
- Scale and trustDistribution and provenance are moving in opposite directions. ChatGPT has reached 1.2 billion weekly active users, a figure attributed to a company executive, while Anthropic is developing FlashProve to verify that a response genuinely came from the model it claims to represent.
- Platform controlPlatform control over AI access is tightening: Google said it will entirely disable Search and Gemini for K-12 accounts in schools that reject its AI features, while Apple opened Siri AI to all developers across iOS, iPadOS, macOS and visionOS 27.3 betas via App Intents.

OpenAI says its GPT-6 Astra model designed a hardware device for the Codex coding agent in under a week, handling enclosure, circuit board, and firmware. Several revision rounds were needed before production because the model didn't always account for manufacturing tolerances, and OpenAI says a newer internal model scores significantly higher on its engineering benchmark without sharing details.

Revolut says it cut AI coding inference costs by roughly 90% in less than a year by making self-hosted GLM models its default over commercial tools like Claude Code. The move highlights a growing trend of enterprises replacing third-party coding assistants with in-house model deployments to control spend.

Anthropic is developing a system called FlashProve that would let anyone verify an AI response genuinely came from the model it claims to be from. The provenance tool addresses growing concerns about model impersonation and spoofed API outputs.

Stanford researchers tested 50 widely cited claims about LLMs against 20 current models and found 44% of the findings are already expired, with another 34% significantly weakened. The average lifespan of a claim is just 15.7 months, and claims about what models cannot do expire fastest.

Google is entirely disabling Search in schools that reject its AI features, according to The New York Times. Google said access to Gemini, Gemini Notebook, Gemini in Classroom, and Google Search will be entirely off for K-12 student accounts in those institutions.

CrowdStrike launched an AI kill switch in its Falcon Guardian product to stop internal AI agents that go rogue, and announced a Falcon Guardian integration with Claude Cowork. The move reflects enterprise demand for controls over autonomous agents operating inside corporate networks.

Apple opened Siri AI to all developers, letting any app on iOS 27.3, iPadOS 27.3, macOS 27.3, and visionOS 27.3 betas bring its content and actions into Siri AI via App Intents. The developer preview significantly expands Siri's integration surface across Apple's platforms.

The SETI Institute and Breakthrough Listen are now using AI agents at the Allen Telescope Array to control the telescope and analyze incoming radio signals. Tasks that used to take weeks can now wrap up in hours, and the team says the system detected a pulsar in the Crab Nebula in real time for the first time.
