Google's models have emerged as the market favorite for second place on OpenRouter's weekly token-share leaderboard for the week of October 12, with traders assigning it a 61.5% implied probability amid a competitive field that also prices AI labs F and G, along with an "Other" category, near even money. DeepSeek's V4.1 Flash model has dominated recent daily and trailing-seven-day volume, consistently claiming first place with tens of trillions of tokens routed and pushing open-weight Chinese labs into the top slots. This leaves the #2 position fluid between Z.ai's GLM series, Stepfun's Step 5 Preview, Xiaomi's MiMo variants, and Tencent's Hy models, all of which posted strong growth in mid-October snapshots. OpenAI's GPT-6 Luna and Anthropic's Claude Opus 5.5 trail further back in the tracked gateway data, reflected in their lower market prices, while Google's Gemini 3.8 Flash shows modest but steady presence that could improve its lab-level share depending on final weekly aggregation. Resolution hinges on OpenRouter's official market-share chart once the full week closes, with any late surges in proprietary or open-weight traffic able to shift the outcome.
