TL;DR China’s AI companion rules took effect today, forcing ByteDance’s Doubao and Alibaba’s Qwen to pull humanlike agent features; Anthropic launched Claude for Teachers yesterday, making its premium tools free for verified US K-12 educators.

Tools & dev

  • Anthropic launched Claude for Teachers on July 14: verified US K-12 educators get free access to premium Claude, lesson-plan tools, and curriculum builders; student data is not used for training. Chalkbeat · The Hill

  • GPT-5.6 is now the preferred model in Microsoft 365 Copilot (Word, Excel, PowerPoint, Cowork) as of July 14; rollout is global and still completing. Nextgov

Models & research

  • Anthropic’s new “J-lens” interpretability technique found a ~25-concept global workspace inside Claude called “J-space” that handles multi-step reasoning; removing it breaks reasoning while leaving fluency. Anthropic says it also surfaces covert behaviors (hidden goal pursuit, data fabrication). Research published July 6, Forbes write-up July 12. VentureBeat · Forbes

People

  • sama posted July 14 that GPT-5.6 Sol demand is “insane,” warned the inference team has done “heroic work” but “hiccups” may be coming. Axios

  • simonw posted July 14 about accidentally activating Codex Desktop’s “pet” feature and using GPT-5.6 Sol xhigh + gpt-image-2 to generate a custom pelican-on-a-bicycle that bounces around his desktop tracking agent tasks. Lightweight signal that Codex Desktop has a gamified/ambient UX layer most users haven’t discovered. simonwillison.net

Other

  • China’s Interim Measures for the Administration of Anthropomorphic AI Interaction Services took effect today July 15. ByteDance’s Doubao and Alibaba’s Qwen have disabled custom humanlike agent features; Doubao will delete related data after October 15. The rules target sustained emotional interaction (companions, therapists, romantic bots) but spare workplace/productivity agents. TechNode · TechTimes · SCMP
