China Finally Beats MYTHOS 5 With New GLM 5.3 (Plus Anthropic’s New Model 2)

China’s Z.ai just revealed GLM 5.3, claiming it beats Anthropic’s Mythos 5 at finding software vulnerabilities while staying open source. Meanwhile Anthropic says its secret Model 2 is getting harder to properly evaluate, as the U.S. pressures countries to choose sides in the growing AI race with China.

🚨 Why It’s Important:
GLM 5.3 shows how quickly China’s open models are closing the gap in advanced cybersecurity. Z.ai is pushing capabilities once restricted to models like Mythos 5 toward open weights, while Anthropic says its newest systems are becoming harder to measure. The open versus gated AI fight is getting much bigger.
