Tokenspeed: Visualizing LLM Token Output Rates
Run tokenspeed to compare your model's actual token throughput.
Run tokenspeed to compare your model's actual token throughput.
Summary
Mike Veerman’s tokenspeed web app provides a visual representation of LLM token output rates, simulating speeds from 5 to 800 tokens per second. The lightweight HTML interface allows developers to see how advertised token‑throughput figures translate into real‑world latency. The source code is hosted on GitHub, enabling easy customization or integration into existing dashboards.
Tokenspeed is particularly useful when evaluating models that claim high token‑per‑second rates, as it demonstrates the practical impact of such claims. The tool can be run locally or embedded in documentation to give stakeholders a tangible sense of model performance. By comparing different models side‑by‑side, developers can make more informed decisions about which LLM to deploy for latency‑sensitive applications. The app is free to use and requires no backend, making it accessible to a wide audience. It complements other token‑rate measurement utilities by providing an intuitive, interactive visual.
