Open Models Tack Toward the Frontier
3 min read
Open-weight models like DeepSeek R1, GLM-4.6, GLM-5.2, and Kimi K3 have matched closed frontier models, but closed systems like GPT-5.2-class and Opus still create step-change advances. The median open-weight model runs about 15% cheaper than GPT-5.2, with DeepSeek V4 Flash roughly 90% cheaper. OpenAI cut inference costs by 50%.
