- DeepSeek's open-source R1 model released in January 2025, which rivals top US AIs and is free, caused a $1 trillion drop in US tech stocks and prompted US lawmakers to propose banning it on government devices.
- Z.ai's GLM-5.2 release in contrast did not cause similar panic, indicating a shift in the US-China AI arms race where China now catches up, similar to other technologies like smartphones and electric cars.
- Chinese AI models are typically open-source and free for local use, while US models are often cloud-based, fee-charging, and closed, leading to differences in accessibility and innovation strategies.
- GLM-5.2 ranks as the most intelligent open-source AI by benchmarks, outperforming GPT-5.5 in software engineering tasks but slightly lagging in intelligence tests, highlighting industry-wide standard testing issues.
