Peter Walker(@PeterJ_Walker):There won’t be another day where open token volume fails to beat closed tokens. The playing field has now shifted to spend. (But also keep in mind this whole market is growing super quickly)

Looks like today may be a record day for token volume % of open models on Vercel AI Gateway: 🟦 Open 78.4% 🟨 Closed 21.6% While spend 💲 usually tells a different story, #3# and #4# today are Moonshot AI & DeepSeek. Adding Z⁠.ai, their combined spend surpasses OpenAI (#2#). (Do note that's the spend for inference of the model across providers (mostly in the US), not revenue going directly to the open weight labs.)
