Summary of Changes

Hello @hpsun1109, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

此拉取请求旨在修复LLM模板中思考预算计算的一个缺陷。它通过引入一个条件检查来确保只有在think标签包含实际文本内容时才计算其token长度，从而避免了因空白或仅含换行符的think内容导致预算被错误地设置为非零值（例如512）的问题。这一改动提高了预算分配的准确性，特别是对于那些不应有思考预算的数据。

Highlights

• 修复思考预算计算错误: 解决了当think标签内容为空或仅包含空白字符（如换行符）时，思考预算被错误地计算为非零值的问题。
• 优化空白内容处理: 确保只有当think标签内包含实际内容时才计算其token长度，从而避免了对“无思考”数据的错误预算分配。

Code Review

本次变更修复了当 <think> 标签中只包含换行符等空白字符时，thinking_budget 被错误计算的问题。通过增加对 think 内容的检查，确保了只在 think 标签内有实际内容时才计算token长度，从而避免了错误的budget设置。此修复是正确且必要的。我提供了一个小建议以提高代码的简洁性。

[gemini-code-assist]

为了使代码更简洁，您可以使用 max() 函数来更新 max_length，从而减少一个嵌套层级，提高代码的可读性。

                            max_length = max(max_length, thinking_token_len)
