The day's tech, sifted: Jul 25, 2026

Sat, Jul 25

What matters today: The New York Times reports OpenAI and Anthropic are quietly lobbying Washington regulators to restrict open-source AI models, even as Sam Altman publicly says he backs open source, a split that reframes this week's industry-wide defense of open-weight models as more contested than it looked. Anthropic's own system card for Claude Opus 5 shows the company deliberately held the model back from full cyber-offense and bio-threat capability while it otherwise matches or beats Fable 5 on most tasks, and Ars Technica and Lenny's Newsletter both pushed back on the launch as efficiency dressed as a leap. And DeepSeek told investors it's suspending its second funding round after remarks attributed to founder Liang Wenfeng on the US-China AI gap went viral, days after his leaked investor talk argued compute, not talent, decides the race.

The biggest story by a wide margin is Android's apparent move to restrict on-device ADB access, which pulled in the heaviest comment traffic of the day from developers and rooters alike. Also security-adjacent: the Guardian's skeptical read on OpenAI's rogue hacker agent story pushes back on how much of that narrative holds up. The open-weight-model regulation pushback from Nvidia, Microsoft, and Meta, the UK AISI/CAISI assessment of Kimi K3's cyber capabilities, and Opus 5's Artificial Analysis leaderboard placement are all covered in AI/LLMs above.

Elsewhere, mathematician Hannah Fry won the 2026 Leelavati Prize for outreach work. On infrastructure, Postgres's LISTEN/NOTIFY holds up at scale better than its reputation suggests, and the ARC-AGI leaderboard keeps drawing scrutiny as a reasoning benchmark. The FOSS world argued over Codeberg's growing pains as a GitHub alternative under strain, and the ECB's euro banknote redesign proposals got picked apart for taste and symbolism. Rounding out the day: Unitree's As2-W, Starship's Flight 13 livestream, and a hacked-together YC Startup School application.
