", "\n\nAbstract\nThis study investigates how English as a foreign language (EFL) learners enact their agency in revising generative AI (GenAI)‐generated academic texts, in this case the statement of purpose, or SOP. Conducted at a key university in Southern China, the study involved 121 English‐major students. This study included two phases. First, we used the Curriculum Vitae (CVs) submitted by the participants to generate SOP drafts through a standardized prompt in ChatGPT‐4. Second, the participants acted as evaluators and editors, engaging with the GenAI‐generated SOPs to varying extents. Nine of the participants attended semi‐structured retrospective interviews. Textual comparison of original and final SOPs was conducted to identify patterns of agency, non‐parametric analysis was performed between learners' ratings and their identified agentic patterns, and thematic analysis was applied to the interview data. The study revealed three agentic revision patterns: compliance‐oriented acceptance, form‐oriented modification, and content‐oriented innovation. Differences in learners' ratings of GenAI‐generated SOPs were found across the three patterns. Two factors influenced these patterns: authentic voice versus GenAI‐constructed textual voice and enthusiasm to present intentions. The study suggests that empowering EFL learners to activate their agency in using GenAI tools enhances their academic writing and supports them in meeting specific task requirements.\n\n\n\n\nPractitioner notes\nWhat is already known about this topic\n\nEFL learners often face challenges in academic writing, particularly in incorporating GenAI‐generated material effectively.\nAgency in revision processes is important for EFL learners using GenAI tools.\nPrevious research highlights the potential of GenAI in supporting writing tasks, but there is limited insight into how EFL learners express their agency during revisions of GenAI‐generated content.\n\nWhat this paper adds\n\nThis study explored how EFL learners enact their agency when revising GenAI‐generated academic texts (ie, SOPs).\nWe identified three specific patterns of agency enactment during the revision process, namely, compliance‐oriented acceptance, form‐oriented modification, and content‐oriented innovation.\nThe research highlighted factors influencing these agency patterns, including authentic voice versus GenAI‐constructed textual voice and enthusiasm to present intentions.\n\nImplications for practice and/or policy\n\nEducators should promote learner agency by encouraging students to recognize and manage their revision strategies, including acceptance, modification, and innovation while using GenAI tools, through instructional strategies that empower effective agency.\nEFL writing instructors should develop critical thinking skills and encourage learners to develop their unique authorial voice, particularly when revising personal and complex texts (e.g., SOPs) to avoid overreliance on GenAI.\nTeachers should guide learners in balancing their authentic identities with GenAI enhancements, ensuring students remain the agents in shaping their voices and conveying the emotional resonance of their experiences in their SOPs.\n\n\n\n\n"]
