TLDR AI’s June 22 issue spotlights Sakana Fugu’s system for coordinating expert models, Mercury 2’s diffusion-based fast reasoning, and Nobel laureate John Jumper’s switch from DeepMind to Anthropic. It also examines audits of diffusion models, the US export controls halting Claude deployments, advances in loop engineering and robotics, and includes a European AI doomsday scenario alongside industry job notes.

• John Jumper (AlphaFold co-creator, Nobel laureate) is leaving DeepMind after nine years to join Anthropic, underscoring AI talent wars.
• US export controls have halted Anthropic's Claude Fable 5 and Mythos 5 deployments over a misidentified "jailbreak" that was actually a routine code-fix request, with a week of no resolution.
• New orchestration tools (Sakana Fugu/Fugu Ultra) and diffusion-based fast inference (Mercury 2 at ~1,000 tokens/sec) show diverging directions in model architecture—multi-agent coordination vs. raw speed.
• Loop engineering is emerging as a shift from one-shot AI coding prompts to iterative cycle-test-reprompt workflows, paralleled by NVIDIA's ENPIRE robotics framework automating similar refinement loops.
