OpenAI plans to launch its first phone in 2028. The company is working with MediaTek and Qualcomm to develop smartphone processors. Mass production is expected to start in 2028. Specifications and suppliers are expected to be finalized by late 2026 or Q1 2027. The phone will likely heavily utilize AI agents, making it work and feel very different from current smartphones.

Apple plans to release the iPhone Ultra and the MacBook Ultra in the next year. The iPhone Ultra will be a foldable iPhone that will likely be released alongside the iPhone 17 Pro, despite not being part of the iPhone 18 lineup. The MacBook Ultra will feature an OLED panel and a touch screen. Its release may be pushed back by several months due to memory supply chain shortages. An AirPods Ultra could also be on the way.

Meta has agreed to purchase up to a gigawatt of solar power from Overview Energy, a startup that aims to deploy satellites capable of providing power to customers on Earth. Overview is working toward an in-space demonstration in 2028. It will target commercial service two years after that. The company is currently developing the satellites along with the production lines to manufacture them.

Advanced semiconductors are the most important technology in the world. However, everyone who hopes to manufacture semiconductors is dependent on ASML, a relatively obscure Dutch company. ASML makes the only machines in the world capable of stenciling the transistors onto a chip with the precision necessary to fit billions on a 30-centimeter wafer. This article tells the story of how ASML overtook its competition to become the sole supplier of these machines.

MCPs give coding agents access to information, not understanding. The engineering teams pulling ahead use a context engine to surface exactly what agents need for every task, so they stay on track without the set up tax or the correction loops. Join live on May 6 (FREE) to see how.

Tesla has filed an S-8 registration statement with the SEC to register 303,960,630 shares of common stock for CEO Elon Musk under his 2018 pay package. The award was contingent on Tesla hitting 12 escalating market cap and operational milestones. It granted Musk options to buy 304 million shares (split-adjusted) at $23.34 per share. Musk must remain CEO or a product development executive at Tesla through to at least 2028 for the shares to vest, and he's required to hold them for five years.

Symphony allows teams to manage work instead of supervising coding agents. It turns project work into isolated, autonomous implementation runs. The agents complete tasks and provide Proof-of-Work, allowing engineers to work at a higher level. Symphony works best in codebases that have adopted harness engineering.

This article discusses how to add memory to agents. The three most common types of mutable memory are Files, Memory Blocks, and Skills. Files are for data and knowledge, Memory Blocks are a flat key-value store, and Skills are indexed files that contain data or instructions that are only needed in certain circumstances. Editable memory makes agents extremely powerful.

OpenAI and Microsoft have forged a new deal that gives OpenAI the freedom to partner with anyone, caps the revenue OpenAI must share with Microsoft through 2030, and removes a clause that allowed OpenAI to limit Microsoft's access to its future technology when systems reach the AGI threshold. The relationship between the two companies was strained last year in part because of the control Microsoft had over OpenAI's intellectual property and exclusivity agreements. The revised deal offers greater predictability for the companies.

China's state planner has told Meta to unwind its $2 billion acquisition of Manus as the sale did not comply with laws and regulations concerning export controls, technology import and exports, and overseas investment.

Microsoft and OpenAI have announced an amended agreement to simplify their partnership and the way they work together.

The Windows K2 plan involves a marathon of updates introduced over time to fix problems in Windows.

OpenAI's Chief Financial Officer is worried the company might not be able to pay for future computing contracts if revenue doesn't grow fast enough.

Open weight models are commoditizing the capability that the American capital-financed AI monopoly was supposed to protect.

Product companies can do faster, less formal, more product-driven experimentation and research, while labs build products that push and inspire companies to build better, more curated services for consumers.
