About Ember-1
Ember-1 is Fireworks Research's specialized foundation model announced September 23, 2026, the first model in the Ember series. Built on Kimi K3 and trained by Fireworks (50+ training experiments; Fireworks Serverless Training) to shorten reasoning traces (~40% fewer tokens while holding quality on Fireworks' evaluations and live A/B tests). Fireworks markets Ember-1 as its own model, a Research Preview on Serverless alongside base Kimi K3, and catalogs it as Fireworks Ember rather than a Kimi family member.
