Fireworks Research ships Ember-1, a token-efficient reasoning model built on Kimi K3

Fireworks Research announced Ember-1, a reasoning model trained on Kimi K3 to deliver comparable quality with roughly 40% fewer tokens. It posts 82.0% on Terminal Bench 2.1 versus K3-max's 80.9% and 75.2% on DeepSWE 1.1, and hit a new Pareto frontier on Doximity's clinical Bedside Bench on cost per task. It launched as a Research Preview on Fireworks Serverless alongside a new 'research releases' program of two-week serverless access windows.
