感谢对bce模型的关注！
bcembedding提供的RerankerModel.rerank方法可以支持32k token长度的passages排序，在readme写了好多地方：

BCEmbedding/BCEmbedding/models/reranker.py

非常感谢你的解答。
1、基于Based on sentence_transformers测试，发现一般900以上文本长度，后续返回的得分都是固定的。这个数值长度是在Based on sentence_transformers中浮动的。
2、基于Based on BCEmbedding测试发现，文本可以支持32k token长度的passages排序。

是的，用BCEmbedding这个包，readme说明得很清楚，BCEmbedding的包封装了我们的业务逻辑。

请问使用bce reranker的时候需要指定文本的最大长度吗（比如max_length=32K），还是模型会自动匹配

不用，最长支持这么多，超过会提示
