+Model merging may inevitably result in performance degradation: even in non-thinking mode, the model might produce lengthy reasoning chains when faced with challenging problems; in thinking mode, it may output reasoning chains without final summaries. 
 
 We are committed to optimizing this in the next version and encourage developers to fine-tune this model or use it as a base for distilling larger models to further enhance performance.
