问HN：你觉得GPT-4.5怎么样？
我发现当任务仅仅需要“写作”时——不涉及编码、工具使用或推理——这是最佳模型。比如校对和建议更好的措辞。我认为在像 progress.openai.com 上的写作任务中，它与 GPT-5 的表现会相当不错。我对它被弃用感到失望，并且在 GPT-5 的演示中没有与它进行任何比较。附言：如果这里有人订阅了专业计划，并且仍然可以访问 4.5，能否请你在 progress.openai.com 上给它输入提示，以看看它与 5 的比较如何？

I found it was the best model when the task at hand required only “writing” - no coding, tool use or reasoning. Like proofreading and suggesting better phrasing.<p>I think it would fare quite well against GPT-5 in writing tasks like the ones progress.openai.com.<p>I’m disappointed it’s been deprecated and there where not any comparisons with it in the GPT-5 demos.<p>ps: if someone here is on the pro plan and that still gives access to 4.5, could you please give it the prompts in progress.openai.com to see how it compares with 5?
