TLDR
A September 19 post reported that open models accounted for 78.4% of Vercel AI Gateway’s token volume that day, versus 21.6% for closed models—a possible record for the open-model share. It ranked Moonshot AI and DeepSeek third and fourth by spending, and said adding Z.ai brought their combined total above second-place OpenAI. The author clarified that this was spending on model inference across providers, mostly in the US, not revenue going directly to the open-weight labs.
