Sylvia Yang (@sophiamyang) spotlights a hands-on comparison by @kickingkeys: the same prompt asked Fireworks AI's Ember-1 and Kimi K3 to each paint with JavaScript, then compared results.
Key numbers: with near-identical composition, Ember-1 used 9x fewer thinking tokens, was 4x faster, and cost half as much. The Fireworks team celebrated the analysis. A useful efficiency benchmark for anyone tracking reasoning cost.
