Claude 3 Haiku vs Gemini 1.5 Flash: Which AI Is Faster?
Two latency-optimized models compared on first-token wait and sustained throughput.
The short answer
There is no single winner — speed depends on the model's inference time and the network path from your connection to each provider. Run the live test below to measure Claude 3 Haiku and Gemini 1.5 Flash from your own location, on TTFT (first-token wait) and TPS (sustained throughput).
Run the live speed test →What the numbers mean
- TTFT (Time to First Token)
- How long until the first token appears — the "reflex" you feel as lag before a reply starts. Lower is better.
- TPS (Tokens Per Second)
- How fast text streams once it starts. Higher is better. See the full methodology.
