| | | ANTHROPIC | | | Anthropic is restoring Claude Fable 5 after the US Department of Commerce lifted export controls on Fable 5 and Mythos 5. | Access to Fable 5 will start returning globally on Claude from Wednesday. | Anthropic also plans to bring it back on AWS, Google Cloud and Microsoft Foundry, though there is no firm date yet. | The models were restricted in early June over jailbreak concerns, blocking access for foreign nationals, including some enterprise users and Anthropic employees outside the US. | Anthropic says it has now trained a stronger safety system to block the jailbreak method flagged by Amazon researchers. | The company says that specific technique is now blocked in more than 99% of cases. Blocked Fable 5 requests will be sent to Opus 4.8 instead. | The company also plans to work more closely with the US government before future model launches, including early testing for models linked to national security risks. | Anthropic is also working with Amazon, Microsoft, Google and others on a shared framework for judging AI jailbreak risks. | It will look at: | | Escape of the compliance dungeon | Anthropic says no AI model can be made fully jailbreak-proof, but no universal jailbreak for Fable 5 has been found so far. | Basically, Claude is coming back, but now with more guardrails, more government involvement, and the kind of launch paperwork that could legally qualify as cardio. | And here I was thinking it was just an Xbox game - MV | Be honest, what does this sound like? | | Vote for live results + see results and opinions from yesterday at the bottom of the email. |

| | | AI IN THE WORKPLACE | | | Most people are using Claude, Anthropic's flagship AI model, like a slightly smarter search bar. The top 10% are using it like a full-time cognitive partner. The difference is knowing which features to actually unlock — and how to stack them. | Stop leaving capability on the table: | Project Spaces: set up a persistent Claude workspace in minutes Agentic Features: delegate multi-step tasks without micromanaging every step Artifacts: generate team-ready charts and diagrams on demand Visual Intelligence: decode any screenshot, image, or document instantly
| The people winning at work aren't working harder — they're prompting smarter. | |

| | | AI SCIENCE | | | Astronomers have built a new AI tool called CIGaRS to help study how the Universe is expanding, and what dark energy might have to do with it. | The tool looks at Type Ia supernovae, huge star explosions used to measure distances in space. | These explosions are useful because they usually shine with a similar brightness, making them a sort of cosmic measuring tape. | The issue is that they are not perfectly identical. | Their brightness can change depending on the galaxy they are in, which can make distance estimates less precise. | In brief: | | AI reads the sky | CIGaRS uses AI and simulated universes to analyse huge numbers of supernovae at once, mostly from images rather than expensive spectroscopy. | That matters because the Vera C. Rubin Observatory is expected to spot millions of them, and scientists will not have time to inspect every cosmic firework manually. | Researchers say the method could make dark energy measurements up to four times more accurate. | Basically, the Universe is about to send a data avalanche, and AI has been handed the shovel. | AI is doing astrology for scientists, basically.- MG |
