Our LLM Token index continues to decline while the debate over open vs closed model rages on. So we decided to take a closer look at how closed and open models respectively contributed. Interestingly, we are seeing some convergence btwn them. The effective prices paid for proprietary models have decreased sharply over the last few weeks as OpenAI releases powerful frontier models at lower prices. Open models otoh have in fact seen their effective prices increase as more powerful near-frontier Chinese models like GLM 5.2 and Kimi K3 are released and served at higher prices. Overall, this should be unsurprising. Econ 101: competition is up and prices are down. This is good for consumer and enterprise users of AI (agents) and promotes much wider and faster AI adoption.
