Mercury: Ultra-fast language models based on diffusion

Damn, that is fast. But it is faster than I can read, so hopefully they can use that speed and turn it into better quality of the output. Because otherwise, I honestly don't see the advantage, in practical terms, over existing LLMs. It's like having a TV with a 200Hz refresh rate, where 100Hz is just fine.

There are plenty of LLM use cases where the output isn’t meant to be read by a human at all. e.g:

parsing unstructured text into structured formats like JSON

translating between natural or programming languages

serving as a reasoning step in agentic systems

So even if it’s “too fast to read,” that speed can still be useful

You're missing another big advantage is cost. If you can do 1000tok/s on a $2/hr H100 vs 60tok/s on the same hardware, you can price it at 1/40th of the price for the same margin.

You can also slow down the hardware (say, dropping the clock and then voltages) to save huge amounts of power, which should be interesting for embedded applications.
