About Ember-1

Ember-1 is a language model from Fireworks AI, published on 23 September 2026. Its base is Kimi K3, the 2.78-trillion-parameter mixture-of-experts model that Moonshot AI built, and Fireworks retrained it rather than starting from a new base. The goal is to reach similar answers while writing less reasoning.

Features

  • Fewer reasoning tokens: about 40 per cent fewer reasoning tokens than Kimi K3 on Fireworks' own tests, at similar quality.
  • Benchmark results: slightly ahead of Kimi K3 on Terminal Bench 2.1 and DeepSWE 1.1, and slightly behind on SWE-bench Verified, in Fireworks' own table.
  • Inputs and outputs: takes text and images and returns text.
  • Tools and structure: supports function calling and structured output.
  • Research preview: two-week serverless access, and the model may be withdrawn or repriced.

Key facts

  • Developer: Fireworks AI.
  • Context length: about one million tokens. Fireworks lists 1,040K, while OpenRouter and Vercel list 1,048,576.
  • Weights: not published.
  • Listed by: OpenRouter and Vercel's AI Gateway, within hours of launch.
