OpenAI GPT-5迟迟未推出，但GPT-5前的两个过渡模型o3和o4-mini已在当地时间4月16日推出了。 这是近期OpenAI频繁调整产品路线图后的最新发布。OpenAI此前曾调整o系列推理模型发布计划，打算不再单独推出o3模型，而是将推出GPT- 5，由GPT-5集成o3。不过，4月初，OpenAI CEO山姆·奥尔特曼（Sam Altman）表示计划有变，因为"整合所有内容比预想的困难"，所以GPT-5 还需要更多研发时间，o3和04-mini还是会先单独推出。 在GPT-5还需等待数月才能面世的空档期，可以用到o3和o4-mini模型的是ChatGPT Plus、Pro、Team用户和API（接口）用户，前代的o1、o3- mini模型将被取代，ChatGPT企业和教育用户后续也能使用o3和o4-mini。从能力上看，这两个新模型则在代码编辑和视觉思考能力方面有较明 显的提升。 "这是我们目前最智能的模型，推理模型首次能代理使用ChatGPT的每个工具，包括搜索网络、使用Python分析上传的文件、推理视觉输入内 容、生成图像。"OpenAI总结称。 具体而言，在外部专家评估中，o3面对困难现 ...

晚上1点，OpenAI的直播如约而至。 其实在预告的时候，几乎已经等于明示了。 这块大概解释一下，别看底下模型那么多，乱七八糟，各种变体。 但是从最早的o1到如今的o3和o4‑mini，核心差别就在于模型规模、推理能力和插件工具的接入。 没有废话，今天发布的就是o3和o4-mini。 但是奥特曼这个老骗子，之前明明说o3不打算单独发布要融到GPT-5里面一起发，结果今天又发了。。。 ChatGPT Plus、Pro和Team用户从今天开始将在模型选择器中看到o3、o4-mini和o4-mini-high，取代o1、o3-mini和o3-mini-high。 我的已经变了，但是我最想要的o3 pro，还要几周才能提供，就很可惜，现在o1 pro被折叠到了更多模型里。 说实话纯粹的模型参数的进步，其实已经没啥可说的了，这次最让我觉得最大的进步点，是两个： 1. 满血版的o3终于可以使用工具了。 2. o3和o4-mini 是o系列中最新的视觉推理模型，第一次能够在思维链中思考图像了。 照例，我一个一个来说，尽可能给大家一个，非常全面完整的总结。 一.o3和o4-mini性能 其实没有特别多的意思，就跟现在数码圈一 ...
