Code Review

This pull request introduces a model validator to synchronize the 'thinking' and 'enable_thinking' keys within 'chat_template_kwargs', ensuring compatibility across different chat templates like Qwen and DeepSeek. Feedback suggests optimizing the implementation by modifying the dictionary in place to avoid unnecessary allocations and re-assignments.

The current implementation creates a shallow copy of the dictionary and re-assigns it to the field even when no changes are necessary. Since chat_template_kwargs is a mutable dictionary, you can modify it in place to avoid unnecessary allocations and re-assignments. This improves efficiency, especially for requests where these specific keys are not present or both are already set.

Suggested change

	d = dict(self.chat_template_kwargs)
	if "thinking" not in d and "enable_thinking" in d:
	d["thinking"] = d["enable_thinking"]
	elif "enable_thinking" not in d and "thinking" in d:
	d["enable_thinking"] = d["thinking"]
	self.chat_template_kwargs = d
	if "thinking" not in self.chat_template_kwargs and "enable_thinking" in self.chat_template_kwargs:
	self.chat_template_kwargs["thinking"] = self.chat_template_kwargs["enable_thinking"]
	elif "enable_thinking" not in self.chat_template_kwargs and "thinking" in self.chat_template_kwargs:
	self.chat_template_kwargs["enable_thinking"] = self.chat_template_kwargs["thinking"]
