Our Take

This pairing highlights the divide between Western and multilingual models. Claude's XML adaptation is about structure; Qwen3's adaptations are about behavior control. Qwen3's thinking mode toggle is particularly powerful -- enabling it for reasoning tasks and disabling it for extraction tasks gives a 15% quality boost.
