**Strong recent growth in low-cost Chinese open-source models and the rapid adoption of new releases like the anonymous Space Bunny Alpha model are the main drivers behind trader expectations for OpenRouter's token usage in the week of September 28, 2026.** Platform data showed weekly volumes reaching 146T tokens in the prior week (ending around September 27), with Chinese models accounting for over 60% of activity thanks to aggressive pricing, strong performance in coding and agentic workloads, and features such as million-token context windows. The late-September launch of Space Bunny Alpha, which quickly entered the top three with double-digit trillions of tokens in its first days, along with updates to DeepSeek V4.1 Flash and GLM 5.3 Flash variants, added fresh momentum. Traders appear to price in continued expansion from these factors and the broader shift toward affordable inference, while viewing a sharp acceleration above 170T or a drop below 155T as less likely given steady but not explosive week-over-week gains observed in recent periods.
