1. AI in Practice: Concrete Milestones and Metrics

1. Gumroad reached a milestone where AI tokens cost equals human payroll, marking AI's deep integration into operations. The team shrank from 32 to 14 (engineering from 21 to 5), and they no longer hire junior/mid-level engineers. AI, particularly Devin, now writes 41% of PRs, with a target of 80% by end of 2026. Customer support SLA dropped from 24 hours to 15 minutes, then to 2 minutes average, and new goal is 300ms. A $25 bug bounty (automated) runs on a $5K monthly budget. — via 1 2 3 4
2. Grok 4.5 achieved state-of-the-art results on Snorkel AI's professional work benchmark, surpassing GPT 5.5 and Claude Opus 4.8 across education, law, and medical domains with the lowest error rate. It also ranks #1 on Long-Horizon Terminal-Bench for complex agent tasks. SpaceX engineering data will be added to further improve Grok. Additionally, Grok for Excel launched for financial modeling and charting. Users report 99% reliance on Grok 4.5 for its speed and low cost. — via 1 2 3
3. Perplexity Computer improved financial data citations: company logos are now displayed, all data traceable to SEC filings and earnings calls, with derived data showing full formula and calculation chains. — via 1
4. Replit agent shipped its first physical product: a lightsaber stand made with OpenSCAD, marking a coding agent creating a real-world object. A unified toolbar integrating database, 2FA, SEO scan, etc. was also released. — via 1 2

2. Industry Shifts: The Rise of Superintelligence and the Death of Software

1. A strong consensus is emerging that "software is dead" and superintelligence has already arrived. @levelsio argues that AI makes everyone equal in the digital realm, and the only winners are superintelligence and AI companies; he no longer uses existing apps, generating personal tools with Claude Code instead. @garrytan agrees that superintelligence is here and speed is the only differentiator. @gregisenberg lists 20 simultaneous AI transformations, including agent counts surpassing humans, software moving from per-seat to per-outcome pricing, and the golden age for builders. — via 1 2 3
2. Vercel AI Gateway data reveals that combined spending share for Anthropic, OpenAI, and Google hit an all-time high of 97.09% on June 27, then dropped to an all-time low in the past 5 days, indicating rapid shifts in the AI model market. — via 1
3. @jackmallers prepares to discuss whether AI could be the largest investment misallocation ever, alongside Bitcoin's rally above $65k, reflecting growing skepticism about AI's ROI. — via [@jackmallers][推文链接](https://x.com/ jackmallers/status/2079320167645852038)

3. New Platforms and Infrastructure

1. Jack Dorsey launched BUZZ, a group chat platform designed for teams and AI agents, aiming to replace Slack and GitHub. It is model-agnostic, decentralized, self-sovereign, and open-source. — via 1
2. X (formerly Twitter) completed a ground-up rewrite of its Android app, making it faster, smoother, and enabling rapid new feature development. This is one of the largest engineering projects in company history. — via 1 2
3. Tesla's Robotaxi service expanded to 7 regions, including Orlando, Miami, and Tampa, with varying driver modes. The Cybercab will feature Starlink V5, no steering wheel, and a large screen for work or 4K streaming. — via 1 2
4. Y Combinator partnered with Together AI to launch the first dedicated GPU cluster for AI startups, addressing compute bottlenecks for over 8,000 customers training and deploying models. — via 1
5. A container ship design using two molten-salt nuclear reactors was approved by the American Bureau of Shipping; the ship can carry 15,000 containers at 25 knots, marking a potential shift in maritime energy. — via 1
