The sovereign AI race is on

Welcome back, Superhuman. That was quick. Despite urging from AI leaders over the weekend, President Trump made it clear the US will not slow down in the AI arms race, even phoning Nvidia CEO Jensen Huang live on stage to voice his thoughts. China isn’t slowing down either — yet another lab just entered the frontier.

Today: Muse’s strong start, learn how to build a personal research assistant with Claude, and get the latest prompts and trending social posts.

1. US and China won’t agree to an AI slowdown: President Trump brushed off the industry’s call for tighter regulations by stating guardrails aren’t necessary and that slowing down would give China a competitive edge. China — which has broadly supported international governance — dismissed Dario Amodei’s recent essay as a tactic to try and “contain” the country’s AI progress. Read the full WSJ report.

2. Meta’s Muse climbs to #2 on the App Store: Meta’s personal AI agent has been downloaded over 83,000 times on iOS, ahead of Threads, WhatsApp, and Facebook, according to US data from Sensor Tower. It now ranks #2 in the App Store’s free apps section, only behind ChatGPT. Chief AI officer Alexandr Wang credited the agent’s performance so far to Meta’s newest family of models, also called Muse.

3. Chinese lab rolls out a research-focused open weight model: The Shanghai Artificial Intelligence Laboratory has released Atria Dawn Preview, a model it claims generates verifiable and reproducible results designed for researchers. The lab claims Atria offers comparable performance to Kimi K3 and Opus 5 on certain metrics, although these claims have not been independently verified. Try it out.

🪰 What’s going on? Researchers from HHMI Janelia and Google Research documented a record-breaking 166,000 neurons and 125 million connections for the male fruit fly (see what that looks like). It marks a major milestone, providing neuroscience researchers with a resource that could lead to breakthroughs…eventually. First, developers are having some fun:

🤔 How does it work? The researchers mapped the brain by using AI to combine millions of 2D images into detailed 3D reconstructions of neural shapes. The end result includes visual-motor pathways that connect to visual neurons, allowing the fly to detect its environment and move in response.

🧠 But why? Experiments like this are a stepping stone. First, researchers map a fly’s brain. Then a mouse’s. Then a monkey’s. Every map reveals a bit more about how each brain functions. The end goal: mapping a human brain (86B neurons).

👀 Everyone Dies: Could AI actually end humanity? A detailed video — originally posted in March — has resurfaced that lays out how this could realistically happen, based on the 2025 book If Anyone Builds It, Everyone Dies. Watch the video here.

📱 Siri’s Here: If you haven’t used it lately, it’s likely time to give Siri another chance. Its AI-fueled iOS 27 update is rolling out today and has already generated plenty of buzz. These infographics break down the need-to-know features.

🎮 Game On: One developer’s video game demo generated 3M views, so he shared the entire step-by-step process behind how he built it using Astra. Check out the story of how he built Paper Route or play the game here.

🤤 Food Prep: This detailed prompt creates highly-realistic food preparation videos from scratch, no reference images needed. The prompt’s length shows just how thorough prompts should be to generate top results (8.7K bookmarks).

😅 Sam Speaks Out: In a lengthy post, Sam Altman says the world deserves to have confidence that labs will act responsibly. For AI to play out safely, he claims we need to avoid these two major risks.

Auth is often the least-tested part of an app. Production needs live credentials, while mocks miss the failures users actually hit.
