Faster decisions with System One What will you train Muse Glimmer to do? Table of Contents TL;DR • Muse Glimmer 30B is free to train with supervised fine-tuning (SFT) through November 30 , kicking off our Free Weights Club. • Tuned Muse Glimmer outperformed Jev by 11.2 percentage points in prediction accuracy on unseen topics , reaching 58.3% versus 47.1%. In a historical backtest, it also turned a hypothetical $1,000 into $1,071 after modeled trading fees , while both Jev and base Glimmer lost money. • Fireworks’ optimized System One serving stack delivered 2-3× faster median server processing than standard BF16 chat completions in a separate synthetic benchmark. Both used the same adapter and a single B200 GPU; precision and runtime differed. • Try our experiment with the Kalshi cookbook .
