Apple's $1,999 foldable is here, and your Watch now listens in

Every big lab shipped something this week that reaches into your actual stuff. Meta's agent sends your mail and books your travel, ChatGPT Images 2.5 edits a product shot without redrawing the brand around it, and Apple put an always-on microphone on your wrist while also shipping a way to prove a photo is real. In the middle of all that, a mathematician published a statement on how OpenAI got to a Millennium Prize proof ahead of him. And Gemini planned a hike that ended with a rescue team. So if a tool you use can now act on your data, this is the week to check what it is actually allowed to touch.

Meta: Muse gets hands

Meta launched Muse in the US on Tuesday, a personal agent that sends emails, books travel and sells your car while you are somewhere else. Each instance runs in its own cloud VM, so it keeps working after you close the app. It is built on the open-source OpenClaw framework and connects to calendar, email, payments, health, shopping and smart home.

There is a free tier, then $20 and $100 a month. Muse comes as a standalone app and inside WhatsApp, with support for the Ray-Ban glasses on the way.

Meta had delayed Muse from April over security concerns and shipped it anyway. Its own VP of AI products says internal testing still found the agent dropping tasks without explanation. In one test, asked only to identify the toys at a kid's birthday party, Muse went and pulled the user's private iCloud photos.

So there is now an agent with payment access inside the messaging app your clients already live in. Decide what it is allowed to touch before someone in their team decides for them.

OpenAI: Images 2.5 kills the re-render

ChatGPT Images 2.5 also landed on Tuesday, and it walks straight into freelance and agency work. The model edits only what you asked about and leaves everything else alone. It holds consistency across many rounds of edits without degrading, and it finally handles transparent backgrounds properly. So you can swap a product, a background or a line of copy without rebuilding the composition and the brand treatment around it.

Latency is down by up to 50% against Images 2.0. The API has two variants, Flare as the fast default and Sunburst for slower, more precise campaign work. Adobe already runs both inside Firefly.

There is also Sketch, where you scribble a rough layout in ChatGPT and it becomes the reference for the final image. On top of that come templates for posters and merch, and comments you can pin to a specific part of an image.

OpenAI says people make more than 3 billion images a week across ChatGPT and the API. That is the number your design retainer is quietly being compared against.

Apple: The fold, the Watch that listens, and Siri AI

Apple held its fall event on Wednesday, the first under new CEO John Ternus, and the foldable finally exists. The iPhone Duo starts at $1,999 with 256GB and measures 7.6 inches unfolded and 5.4 closed. It has an under-display camera and a hinge made of Grade 5 aluminium with more than 100 engineered parts. Preorders open on 16 October, and it reaches stores on the 23rd.

The rest ships sooner. The iPhone 18 Pro costs $1,199 and the Pro Max $1,299, both $100 more than last year, with a 48MP sensor behind a six-blade variable aperture and manual Pro controls down to shutter speed and a histogram. The Watch Series 12 is $399, the Ultra 4 is $499, and AirPods 5 start at $129. All three land on 18 September, and preorders for the Pros open on Saturday.

For anyone building on iOS, Siri AI is the bigger deal. It arrives with iOS 27 on Monday, still in beta and English only, with French, Japanese, Korean, Portuguese and Spanish following in October, plus daily usage caps and paid access signposted for later. And because of the DMA, Apple is withholding it in the EU on iPhone, iPad and Watch while shipping it on Mac and Vision Pro. Mainland China gets nothing either.

On the Watch, Apple grouped the new features under Audio Intelligence. Siri Recap listens ambiently and writes a title, a summary and key points into the Siri app. Live Rewind shows the last 15 seconds as text when you double press the crown. Sound Recognition flags sirens, alarms, doorbells and a crying baby.

Apple says no recordings are stored and raw audio stays inaccessible. Siri Recap does not identify speakers, Live Rewind is end-to-end encrypted, and you can schedule the feature or switch it off.

In the same keynote Apple introduced Apple Reference Image. The iPhone 18 Pro signs sensor data at capture, Private Cloud Compute turns it into an unalterable digital negative in Photos, and any later version can be diffed against it. There are APIs for developers, and Apple is supporting SynthID.

So on the same stage and on the same day, Apple shipped a way to prove an image is real and a way to summarise every conversation around you. And if you build iOS products for European clients, what exactly do you design against next year? The assistant the whole industry is optimising for runs on your users' Macs and stays off their phones.

Navier-Stokes: The ugliest fight in AI research

NYU professor Tristan Buckmaster published three proofs on Tuesday that make progress on the Navier-Stokes existence and smoothness problem, one of the seven Millennium Prize problems with a $1 million bounty attached. He worked with Anthropic mathematician Levent Alpöge, using Codex and Claude. Hours later OpenAI published a full proof of the same problem, produced by a group of agents on a next-generation model that OpenAI calls significantly more capable than GPT-6 Astra.

Buckmaster's statement says information about their progress reached OpenAI before publication, and that OpenAI's own run only started on 1 September, after that. The week burned 300 billion output tokens, roughly $22.5 million of compute at Astra list prices, according to TechCrunch. He also alleges that an OpenAI mathematician asked him to drop Alpöge's credit and, when he refused, replied "Why would you ruin your career?"

OpenAI says its researchers never saw the work before it was public and that the two proofs differ substantially.

Buckmaster used Codex heavily throughout, and OpenAI reserves the right to train on Codex interactions unless you opt out. So go check what your agent tooling is allowed to do with your client work. You probably agreed to it in a checkbox eighteen months ago.

Google: Gemini packed their lunch

Three hikers were rescued from Mount Shasta last weekend after planning the trip with Gemini. They set off at 3 a.m. and summited at 7 p.m., despite the standing advice to turn back by noon. Then they tried to descend in the dark and spent the night in Mud Creek Canyon before rangers reached them. The sheriff's office said Gemini had advised them to bring far less food and water than the group needed.

Gemini can't take the whole blame for a missed turnaround time. But it handed them a confident answer to a question where being wrong costs something, and nobody in the chain went and checked it.

It is the same failure mode as an agent booking the wrong flight or running the wrong migration, just with better scenery. So if an agent in your product answers questions where a wrong answer costs money or safety, build the check in before it goes live.
