Recently, Jieyue Xingchen took a significant stride by fully open-sourcing its latest-generation base model, Step 3.5 Flash. By March 6th, this model had claimed the number one position globally in terms of call volume on the OpenClaw platform for two days in succession. Overseas developers have observed that the degree of open-sourcing Step 3.5 Flash has achieved is a rarity in today's large model market. The Jieyue Xingchen algorithm team went beyond just open-sourcing the model; they also made available the pre-training weights, intermediate training weights, and the accompanying training framework. This comprehensive approach empowers developers to engage in secondary development with flexibility. Developers can leverage the open-source framework and technical reports to foster innovation and exploration based on this model.
