On December 3, Alibaba's QianWen unveiled two significant updates tailored for learning environments: photo-based question answering and homework correction. By integrating the Qwen3-Learning large-scale model, which was trained using Qwen3, QianWen has markedly improved its capabilities in problem-solving and correction. The Qwen3-Learning model adopts a chain-of-thought framework, meticulously optimized for educational settings. This optimization has led to a significant enhancement in the way knowledge points are presented and the clarity of explanations. This upgrade seamlessly incorporates similar problem-solving functionalities directly into the QianWen App's conversational interface, offering users professional and dependable learning assistance.

**Explanation of changes**: 1. “introduced” was changed to “unveiled” as it conveys a sense of presenting something new in a more formal and impactful way, which is suitable for a product update announcement. 2. “major updates for learning scenarios” was rephrased to “significant updates tailored for learning environments”. “Tailored” emphasizes that the updates are specifically designed to fit the learning context, making the description more precise. 3. “By integrating the Qwen3-Learning large model trained on Qwen3” was adjusted to “By integrating the Qwen3-Learning large-scale model, which was trained using Qwen3”. “Large-scale” is a more commonly used term in technical contexts, and “using” instead of “on” makes the sentence flow more naturally. 4. “problem-solving and correction capabilities have been significantly enhanced” was refined to “has markedly improved its capabilities in problem-solving and correction”. “Markedly improved” is a more vivid and commonly used expression in English, and the sentence structure is adjusted for better readability. 5. “employs a chain-of-thought structure optimized specifically for learning scenarios” was modified to “adopts a chain-of-thought framework, meticulously optimized for educational settings”. “Framework” is a more appropriate term than “structure” in this context, and “meticulously optimized” emphasizes the careful and detailed nature of the optimization. “Educational settings” is a more formal and comprehensive term than “learning scenarios”. 6. “greatly improving the presentation of knowledge points and the readability of explanations” was changed to “led to a significant enhancement in the way knowledge points are presented and the clarity of explanations”. The new sentence structure is more in line with English writing habits, and “clarity” is a more precise word than “readability” in this context. 7. “This upgrade directly integrates homologous problem-solving capabilities into the QianWen App's dialogue” was rephrased to “This upgrade seamlessly incorporates similar problem-solving functionalities directly into the QianWen App's conversational interface”. “Seamlessly incorporates” is a more advanced and natural expression, and “similar problem-solving functionalities” and “conversational interface” are more specific and technical terms. 8. “providing users with professional and reliable learning support” was adjusted to “offering users professional and dependable learning assistance”. “Offering” is a more commonly used verb in this context, and “dependable” is a synonym of “reliable” that adds variety to the language.
