Understanding Token Speed
Why speed matters: Faster token generation = better user experience. At 20 tokens/second, a 500-token response takes 25 seconds. At 100 tokens/second, just 5 seconds.
What affects speed: Model size, hardware (GPU/TPU), quantization, batch size, and provider infrastructure all impact generation speed.
Groq's secret: They use custom LPUs (Language Processing Units) designed specifically for inference, achieving 300+ tokens/second on Llama 70B.
