OpenRouter Report: Open-Source Models Hit 60% Share, Chinese Models ~70%

OpenRouter released a platform usage report during Tech Week in San Francisco, and blogger Tiancaixinxin summarized the key data in a thread. The overall picture: open-source models are taking over traffic, agents have become the dominant callers, model switching is accelerating, and costs have dropped sharply.

Confirmed

Open-source models' share of total usage rose from about 25% in January to roughly 60% in September, nearly all of them Chinese models, which account for about 70% of weekly token volume.
Agent traffic surpassed human traffic starting February 16 this year; labs shifted to agentic workloads at different times — for example, there's a gap between Claude Opus and DeepSeek V4.
Organizations now use an average of 12 models as of September, up from 8 in January; tasks like file I/O, shell execution, DevOps configuration, frontend UI, debugging, and SQL are rapidly migrating to models.
The blended average price fell 82%.
Citing demo data from OpenRouter's Peter Walker: Jev captured a 32% weekly share of all categorized requests on OpenRouter just 2 weeks after launch.

Why it matters

Open-source (especially Chinese) models now account for over half of real production traffic, marking a substantive shift in the AI inference market — not just leaderboard performance.
Agent traffic exceeding human traffic means the primary API caller is shifting from people to automated systems, with implications for product and billing models.
With organizations swapping models 12 times a year on average and prices down 82%, models are highly commoditized, pushing procurement toward multi-model mixes and rapid switching.
