GPT-5.5 Beats Fable, Cursor Takes On GitHub & Midjourney Scans Your Body | This Week in AI

Fable is gone, and the race to replace it is already on. Shane and Abhi open with the fallout — reports that Mythos breached classified NSA systems, the ID-verification future that may follow, and David Sacks' "you asked for it" take. Then the story flips: OpenAI's GPT-5.5 Cyber lands state-of-the-art on Cyber Gym, beating Fable and Mythos on the underlying benchmarks, with OpenAI Daybreak shipping alongside it. GPT-5.6 leaks, then slips to mid-July. GLM 5.2 arrives near Opus 4.8, tops Design Arena, and runs on a Mac. Cursor goes after GitHub with Origin, adds mobile and its own frontier model on Colossus after the SpaceX deal closes. Vercel ships Eve, Fred Schott counters with Flue, Claude lands in Slack, and Midjourney — yes, the image company — unveils a full-body medical scanner headed for spas.
