这篇论文通过分析Reddit上的讨论，揭示了模型发布如何影响用户对对话式AI系统的看法，对于了解AI产品与用户互动有重要意义。
研究分析了Reddit上关于对话式AI系统（CAISes）的讨论，发现用户对CAIS模型发布的看法是动态和敏感的。Anthropic通过Claude Code和产品-模型匹配展现出最清晰的正面发布形象，OpenAI在GPT-5和GPT-5.1周围表现出反感和恢复的动态，Grok-3受供应商身份和政治话语影响，DeepSeek-R1结合了对工程成就的赞扬和对审查、访问和可靠性的担忧。模型发布不仅仅是技术更新，而是影响用户情绪、期望和公共讨论的用户界面干预。
Expectation, Backlash, Recovery, and Excitement: How Model Releases Shape Reddit Perceptions of Conversational AI Systems
Conversational AI systems (CAISes) continuously change through model releases, feature updates, safety interventions, and access-policy shifts, yet user perceptions are often studied as static snapshots. We conduct a long-term, large-scale analysis of Reddit discussions to examine how users perceive CAIS model release interventions across providers. By combining sentiment classification and thematic concept analysis, we show that CAIS perceptions are dynamic and intervention-sensitive. Anthropic exhibits the clearest positive release profile through Claude Code and product-model fit, OpenAI shows backlash-and-recovery dynamics around GPT-5 and GPT-5.1, Grok-3 is shaped by provider identity and political discourse, and DeepSeek-R1 combines engineering praise with concerns about censorship, access, and reliability. These findings show that model releases are not merely technical updates, but user-facing interventions that reshape sentiment, expectations, and public discussion.
