Echo is an open-source system that dynamically orchestrates a pool of open-weight models to achieve performance comparable to Fable at one-third the inference cost. By intelligently allocating computation and combining outputs from complementary models like GLM-5.2 and Kimi K2.7, it adapts to each request's complexity without prior knowledge of the optimal solution.
Background
The AI industry is increasingly exploring model ensembling and routing strategies to balance performance with computational efficiency, moving beyond reliance on single monolithic models.
