Fireworks previews Ultra-fast, targeting 6-8x generation speed on Serverless

Top News

If token generation is holding up your application, Fireworks has a new serving mode to test. Ultra-fast runs DeepSeek V4.1 Flash 1017 on Serverless without changing the underlying model. You select it with a dedicated model ID rather than moving to a different model.

Here's what changed:

  • Ultra-fast variants aim for 6-8x generation speed.
  • Agentic coding targets go as high as 10x, according to Fireworks.
  • Output quality stays the same because Ultra-fast changes the inference mode, not the model.

One catch: Ultra-fast is in Preview and under active development, so its behavior or availability may change quickly.

Try it: On Fireworks Serverless, set the model to accounts/fireworks/routers/deepseek-v4p1-flash-1017-ultrafast.
