DeepSeek's V4.1 Flash model and related variants have driven its commanding position on OpenRouter through aggressive pricing, strong coding and agentic performance, and high token throughput among developers, with recent weekly snapshots showing the lab aggregating the largest share via multiple high-volume routes. This aligns with the broader trend of Chinese labs capturing majority platform usage through cost advantages and rapid iteration that favor high-volume, price-sensitive workloads over frontier benchmarks. Trader consensus at 96% reflects consistent recent data favoring DeepSeek for the week of September 28, though a surge in a new anonymous model such as Space Bunny Alpha or unexpected spikes from labs like Z.ai or Xiaomi could still shift the outcome before resolution.
