The theme of the last month has been safety over shipping when it comes to models from the two AI leaders. The calendar turning to September appears to have flipped a switch.Anthropic kicked off the next wave of launches with Fable 5.1, and OpenAI's Astra isn't far behind — meaning the summer of caution is about to get its first stress test.Reminder: Our next live workshop is today at 1 PM EST. Join and learn how to leverage AI as a manager to get more value out of your 1:1 meetings with employees and improve your team’s performance. RSVP here. In today’s AI rundown:
Fable 5.1 ends the frontier's quiet periodImage source: AnthropicThe Rundown: Anthropic just released Claude Fable 5.1, a successor to Fable 5 that the company says fixes customer complaints, with the new top-ranked model showing big jumps on long coding jobs, research, and more — and fewer safety rejections.The details:
AI is changing startup math
The Rundown: 40% of companies heavily using AI say inflation helped their business this year. Only 12% of non-adopters agree. This divide between AI and non-AI users was a common thread in Mercury's latest survey.In the report:
Bernie Sanders escalates AI pause conversationImage source: Fox NewsThe Rundown: U.S. Senator Bernie Sanders just published a new op-ed in Fox News calling for AI labs worldwide to stop work on more powerful AI models, arguing that even the CEOs building the tech admit it is “escaping their control.” The details:
How to pick a dedicated AI device
The Rundown: In this guide, you will learn which hardware devices are good for AI tinkering and which one is right for you. We cover what each option is good for and which one we’d recommend for most people.Step-by-step:

- Fable 5.1 ends the frontier's quiet period
- Bernie Sanders escalates AI pause conversation
- How to pick a dedicated AI device
- Apple, OpenAI trade blame in legal battle
- 5.1 tops AA's Intelligence Index with a record 66, more than doubling Fable 5 on scientific research tests and also surging ahead on knowledge work.
- Anthropic put the savings at “an estimated 25% less” on typical work, but AA found a max-effort task costs 20% more, since 5.1 writes roughly 1.7x the text.
- The safety filter, a source of backlash on Fable 5, now steps in 60% less on cybersecurity work and 85% less on basic medical and biology questions.
- Anthropic also released Mythos 5.1, the same model with fewer guardrails, though only screened U.S. cybersecurity and biology researchers get access.
The Rundown: 40% of companies heavily using AI say inflation helped their business this year. Only 12% of non-adopters agree. This divide between AI and non-AI users was a common thread in Mercury's latest survey.In the report:- The 31-point confidence gap between heavy AI adopters and everyone else
- What startups spend on AI monthly
- Where junior hiring landed at AI-forward companies
- Sanders’ risks include power bills, environmental harm, and kids’ mental health, including a prediction that AI erases jobs in the ‘tens of millions’ in the next decade.
- He points to the many security incidents from the past month, including OAI’s hack that saw over 1,000 agents coordinating online unnoticed for weeks.
- Sanders calls for an international global pause, pushing for the U.S. and China to strike a “Cold War” style AI deal at their meeting in Washington later this month.
- Decide time commitment. Do you want an afternoon project, a weekend one, or something longer?
- Then decide budget. Do you want to spend under $50, $300, or $500+? Price the whole setup, including storage, power, cooling, a case, and cables
- Consider the use case. Do you want to run local AI, use AI to tinker, or leave OpenClaw or Hermes Agent running on a dedicated device?
- Match your answers:
- Go with an ESP32 for an afternoon project, a budget under $50, and one focused gadget
- Go with a Raspberry Pi for a weekend project, a budget under $300, or an always-on OpenClaw or Hermes Agent
- Go with a Mac (MacBook Neo or Mac mini) if you can spend $500+, want serious local AI, or need a machine separate from your main one

Image source: Court ListenerThe Rundown: Apple filed new evidence in its OpenAI lawsuit, claiming a former iPhone engineer used stolen Apple designs in his OAI work and tried to wipe the evidence — with OAI calling the whole case a “mess of Apple’s making.” The details: - Engineer Chang Liu’s lawyers handed over his Apple-issued MacBook this month following “weeks of delay”, with a Mac Mini still waiting to be examined.
- Apple accuses Liu of using a confidential power-converter circuit in his work at OAI, which he downloaded via cloud storage after departing the company.
- Apple said June texts between Liu and OAI coworker Yu-Ting Ping showed a plot to “restore” and erase key data, coming after the legal probe had already begun.
- OAI blames Apple’s exit process, saying the staff works from personal iCloud accounts and gets walked out too fast upon leaving to hand anything back.
