zhipu ai's glm-5.2, a 744 billion parameter chinese model with a 1 million token context window, ranked second on the code arena leaderboard and drew positive assessments from silicon valley developers on coding tasks, placing it close to anthropic's fable 5. within hours of the anthropic export control announcement, japanese startup sakana released fugu, an openai-compatible multi-agent system explicitly marketed as resilient infrastructure that routes queries across multiple vendors to avoid single-vendor dependency — framing the export control directly as the use case. the speed of the circumvention response and the simultaneous chinese benchmark advance together signal that the controls accelerated rather than contained capability diffusion.
