The DigitalOcean Inference Engine introduces a new server-side tool, model synthesis, which outperforms Fable 5 by synthesizing outputs from multiple models at a lower cost. The benchmark testing reveals that the open-source model combination of GLM 5.2 and Kimi K2.6 not only delivers higher quality but does so more economically than frontier models. This blog elaborates on how model synthesis can enhance cost-efficient and high-quality AI outputs for research-heavy tasks.
