Product Idea from this Signal

258 ▲

Generic benchmarks like MMLU and HumanEval don't predict which model is cheapest for your specific agent workflows. StepFun 3.5 Flash won a 300-battle benchmark but may lose on your use case. This service records your real OpenClaw agent tasks, replays them against every new model as it launches, and gives you personalized cost-performance rankings. When a cheaper model can handle your workload without quality loss, it alerts you with projected monthly savings.
