OpenAI's iPhone competitor

Welcome back, Superhuman. On Sunday, Sam Altman cryptically posted that it’s time to “seriously rethink” how operating systems and user interfaces are designed. A day later, reports surfaced that OpenAI is working on a ChatGPT-powered phone.

Today: OpenAI’s rumored phone, how to set up and use Claude Design, and get the latest prompts and trending social posts.

TODAY IN AI

1. OpenAI is reportedly building its own phone: OpenAI has reportedly partnered with MediaTek, Qualcomm, and Luxshare to build a cell phone, likely running on its own operating system with AI agents potentially replacing apps. The rumored phone joins a growing list of hardware products in development, including a ChatGPT-infused smart speaker, smart glasses, and smart lamp.

2. Copilot in Outlook gets agentic: Microsoft Outlook now supports Agent Mode, helping to run your inbox and calendar more efficiently. Just tell Copilot what you need done and it’ll get started — keeping you in the loop along the way so you can make adjustments as needed. Available now in Microsoft’s Frontier program. See how it works or try it out with these four prompts.

3. China blocks Meta's $2B Manus acquisition: With no explanation offered, Chinese officials ordered Meta and Manus to unwind their deal, capping a months-long probe. The veto extends beyond Meta: Chinese regulators have recently told AI labs like Moonshot and Stepfun to reject US capital, signaling Beijing's broader move to fence off its homegrown AI sector.

FROM THE FRONTIER

Elon Musk and Sam Altman’s court case officially kicked off yesterday — with $134B at stake

The trial of the century. Elon Musk v. Sam Altman is officially underway, with jury selection starting yesterday. The trial has all the markings of a Shakespearean drama: ego, deceit, and — with both OpenAI and xAI preparing to go public — billions of dollars on the line.

The conflict. Musk and Altman cofounded OpenAI in 2015 as a nonprofit research lab with one goal: build AI that benefits humanity. Today, it’s a for-profit juggernaut worth nearly $1T. Musk alleges that he was duped during the restructuring and that Altman broke the law by converting OpenAI to a for-profit. OpenAI called the lawsuit a "harassment campaign driven by Musk's ego, jealousy, and desire to slow down a competitor."

What's at stake. Musk wants Altman removed from leadership, the for-profit conversion unwound, and up to $134 billion in damages directed to OpenAI’s nonprofit. These outcomes could hinder OpenAI’s upcoming IPO, potentially benefiting Musk’s xAI by hurting a major competitor.

The stage is set. The witness list includes Microsoft CEO Satya Nadella, OpenAI president Greg Brockman, and former OpenAI executives — with both Musk and Altman themselves set to take the stand.
