Chinese open model builders including DeepSeek, Qwen, and others are releasing frontier-quality open models at high cadence, with DeepSeek's V3 and R1 representing the biggest AI stories of 2025 through permissive licensing and transparent reasoning chains.

The AI safety debate has shifted from adversarial 'doomers vs accelerationists' framing to unified coordination on technical solutions, driven by constraints from geopolitical competition, economic dependencies, and existential stakes.

Open models will never catch up with closed frontier systems in raw capability, but this is the wrong framing—open models serve as the engine for exploratory AI research that companies cannot nurture.

“Argues that open models will never catch up with closed ones but believes they will be the engine for the next ten years of AI research.”
