Fireworks AI announced that @FactoryAI joins its Specialized Intelligence Index with Legacy-Bench, testing how models handle legacy software behind payroll and financial settlement. Teams can now submit proprietary benchmarks: Fireworks covers compute, runs leading open and closed models, keeps tasks/prompts/trajectories private by default, publishes quality-cost-latency comparisons, and can post-train models on identified failure modes. Signals a shift from generic leaderboards to domain-specific, real-work evaluations.
