APPLE'S IPHONE DUO, NEW WATCHES, IPHONE 18 PRO, AND AIRPODS 5: EVERYTHING TO KNOW

Apple's first foldable iPhone, the iPhone Duo, starts at $1,999. The device expands to a 7.6-inch screen when unfolded, and a 5.4-inch screen when used as a conventional handset. It comes in two colors: Star White and Night Sky. More details on the device, as well as Apple's other recent releases, are available in the article.

APPLE TAKES ON AI WEARABLES WITH ALWAYS-LISTENING WATCH FEATURES

The Apple Watch Series 12 and Ultra models have new Audio Intelligence tools that use ambient listening to take high-level notes of wearers' conversations throughout the day. The devices will also have a Live Recap function that can show a transcription of what was said in a live conversation in the last 15 seconds and be able to listen to important sounds, such as a crying baby, doorbells, or sirens. These features will not create or store recordings, and Apple will not be able to access the raw audio. They will be available to test in English later this year. The improved Siri is being rolled out on watchOS 27 in beta on September 14.

GENOME LANGUAGE MODELS CAN DESIGN CANCER VACCINES

Modern cancer-vaccine design involves identifying mutations, predicting presentation, predicting immunogenicity, ranking targets, and designing RNA. However, biology is complicated, and whether a target makes a good vaccine candidate depends on all kinds of information. This makes cancer vaccines an unusually direct test of whether AI models can take what it has learned from biology and apply that knowledge to design a medicine for one particular human being.

SCENARIOS FOR OUR ECONOMIC FUTURE

It is unknown yet whether AI will lead to unprecedented growth or widespread unemployment. Anthropic's Economics team built a model to understand how AI might affect jobs, growth, and unemployment in the US in the coming years. The model found that AI will lead to adverse impacts on wages and job prospects for knowledge workers in scenarios where growth is faster than anything in economic history, and in those scenarios, the challenge will be making sure wealth is broadly shared. The answer will depend on how AI affects all the tasks that make up the economy, the new tasks it creates, and how fast AI takes on this work.

MULTIMODAL MODELS NEED VIDEO. WE FROZE TIME TO GIVE IT TO THEM

PostHog's Replay Vision lets models view session recordings. This post looks at how PostHog built the tool and how it implemented a method for the model to actually see replays. It covers how PostHog built a custom rasterizer that runs hundreds of concurrent jobs across many pods. The custom rasterizer has so far rasterized more than 370 years of recordings into roughly 3.5 million videos since it was deployed in production in March.

TAILWIND LABS IS JOINING SHOPIFY

Tailwind is joining Shopify, one of the first companies operating at scale to see the potential of Tailwind CSS and start building with it. Shopify has invested in making sure Tailwind is actively maintained and will continue to provide a stable long-term home for the project. Nothing will change with Tailwind CSS or any of Tailwind's other open source projects, but the project will no longer try to grow its business. All existing customers will maintain access to their products, but Tailwind has closed signups for new customers.

AUTOMATTIC'S BOARD FORCES CEO MATT MULLENWEG INTO LEAVE OF ABSENCE

Automattic's board has put founder and CEO Matt Mullenweg on a leave of absence against his will. The company's Chief Financial Officer, Mark Davies, had conspired with other board members to put Mullenweg on a paid leave of absence. Davies is now acting as interim CEO. Mullenweg remains the leader of the WordPress project, and the company's teams, priorities, and work will continue as planned. It is unclear why the board took this action. Mullenweg remains on the board of directors.

CRACKS IN THE AI THESIS PART 2

The price of AI is coming down. However, volume growth may not be large enough to counteract the effective decline in prices. The models driving volume increases are relatively cheap, standard models. These trends do not appear to be driven by the adoption of open-source models or Chinese models.

PROMPT EVALS ALONE ARE USELESS

A system that improves itself needs guardrails and a sandbox.

THE CACHE IS THE PRICE

While GPT-6 Astra and Claude Fable 5.1 seem to have the same rates, Fable's cache read is four times cheaper.

Purchasers of open source work should be able to check whether a vendor contributes.

ON THE NAVIER–STOKES MILLENNIUM PRIZE PROBLEM

OpenAI heard that some Millennium Prize problems had been solved using large language models and saw it as an opportunity to demonstrate the power of its latest model without regard for the teams who had been working on the problem already.
