7年了，OpenAI官方给出五代GPT对比，网友却怀念起「狂野」初代

Core Viewpoint - The article discusses the evolution of the GPT series models from GPT-1 to GPT-5, highlighting significant improvements in their capabilities, particularly in understanding and generating coherent responses to complex queries [2][5][49]. Group 1: Evolution of GPT Models - GPT-1 was characterized by awkward and nonsensical responses, demonstrating limited understanding of complex questions [2][11][12]. - GPT-5, in contrast, provides well-structured, coherent, and contextually relevant answers, showcasing a significant leap in performance over its predecessors [5][20][49]. - The internal experiences of OpenAI personnel reflect the profound changes in the model's capabilities over seven years of development [6][49]. Group 2: Specific Comparisons - When asked about the feasibility of annual full-body MRI scans for cancer detection, GPT-1's response was illogical and confusing, while GPT-2 offered a slightly better but still unhelpful answer [11][12]. - GPT-4 provided a more reliable response but lacked a personal touch, whereas GPT-5 not only addressed the question effectively but also engaged with emotional value, resembling a conversation with a knowledgeable doctor [20][21][49]. - The article emphasizes that GPT-5's responses are not only accurate but also considerate, indicating a shift towards more human-like interaction [20][21][49]. Group 3: User Reactions - The article notes varied user opinions on the different GPT models, with some expressing nostalgia for the wild and unpredictable nature of GPT-1, suggesting it had a unique appeal [50][51]. - There are comments suggesting that GPT-1 felt more like a "true AGI" compared to its successors, indicating a divergence in user preferences [53][54].
