Li Feifan

At the 2026 ITValue Summit Digital Value Conference, TMTPost Group partner Li Feifan launched TiToken, a multi-token aggregation and solutions platform, and BackBy, a compute optimization product. TiToken provides multi-model token relay services, with Opensand as the overseas service platform. BackBy moves wait-tolerant tasks such as field extraction, document classification, and summarization into lower-cost batch paths to reduce model call costs. Delivery uses an FDE model, and the product has been deployed in three real-world scenarios.
