thefastest.ai is a benchmarking platform that provides reliable measurements for the performance of popular large language models (LLMs). It tracks key metrics such as Time To First Token (TTFT), Tokens Per Second (TPS), and total response time from request to final token. The platform allows users to filter models by provider, region (US West, US East, Europe), and prompt type (text, function, image, audio). Data is updated daily and sourced from a public GCS bucket, with the full test suite available in an open-source repository. The methodology includes distributed testing across multiple data centers, connection warmup, and a 'try 3, keep 1' approach to remove outliers. thefastest.ai aims to provide realistic latency and throughput benchmarks to help users evaluate LLM speed for conversational applications.
