Usage charts for my LLM tool against OpenRouter. OpenRouter proxies requests to a large number of different LLMs and provides high level statistics of which models are the most popular among their users.

Tools that call OpenRouter can include HTTP-Referer and X-Title headers to credit that tool with the token usage. My llm-openrouter plugin does that here.

... which means this page displays aggregate stats across users of that plugin! Looks like someone has been running a lot of traffic through Qwen 3 14B recently.

Screenshot of LLM usage statistics dashboard showing a stacked bar chart from July 5 to August 4, 2025, with a legend on the right displaying "Top models" including Qwen: Qwen3 14B (480M), Google: Gemini 2.5 Flash Lite Preview 06-17 (31.7M), Horizon Beta (3.77M), Google: Gemini 2.5 Flash Lite (1.67M), google/gemini-2.0-flash-exp (1.14M), DeepSeek: DeepSeek V3 0324 (1.11M), Meta: Llama 3.3 70B Instruct (228K), Others (220K), Qwen: Qwen3 Coder (218K), MoonshotAI: Kimi K2 (132K), and Horizon Alpha (75K), with a total of 520M usage shown for August 3, 2025.
