How the top providers stack up against each other in real-world latency.
What is the fastest AI model right now?
The rankings above update continuously based on real user measurements. The fastest provider varies by your location and network conditions, but the top-ranked model on this page consistently delivers the lowest average response time across all global users.
How is speed measured?
We measure Time to First Byte (TTFB), which is the time from sending a request to receiving the first byte of the response. This captures the real latency users experience, including network transit and server processing time. All measurements come from actual users, not synthetic tests.
Is GPT faster than Claude?
It depends on when and where you test. Our data shows that response times for both OpenAI (GPT) and Anthropic (Claude) vary by region and time of day. Check the live rankings above for the latest comparison, or run your own speed test to see which is faster from your location.
How often are rankings updated?
Rankings update continuously as new test results come in from users worldwide. The data shown represents a rolling 30-day average to smooth out temporary fluctuations while still reflecting current performance.
