OpenAI首席执行官Sam Altman在X上发布了公司GPT-4.5和GPT-5人工智能模型的路线图。Altman承认OpenAI的产品线已经变得复杂，并表示公司希望更好地简化其产品。GPT-4.5（内部代号Orion）将是OpenAI的“最后一个非思维链模型”。在GPT-4.5之后，OpenAI的首要目标是通过创建可以使用所有工具的系统来统一o系列模型和GPT系列模型。OpenAI计划将GPT-5作为整合多项技术的系统发布，包括o3。Altman表示，免费ChatGPT用户将获得“无限的聊天访问权限”，而Plus和Pro订阅者将能够以更高的智能水平使用GPT-5。Altman并未透露GPT-4.5和GPT-5的具体发布时间，但给出了“几周/几个月”的模糊估计。

🚀 OpenAI计划发布GPT-4.5，内部代号为Orion，这将是最后一个非思维链模型，旨在简化产品并提高AI的易用性。

💡 在GPT-4.5之后，OpenAI将致力于统一o系列和GPT系列模型，创建能够使用所有工具、判断思考时间长短的系统，以适用于更广泛的任务。

🎁 GPT-5将整合OpenAI的多项技术，包括o3，并且不再单独发布o3模型。免费ChatGPT用户将获得无限聊天访问权限，而Plus和Pro订阅者将能够以不同智能水平使用GPT-5。

📅 Altman给出了GPT-4.5和GPT-5的发布时间预估，大约在“几周/几个月”内。

OpenAI CEO Sam Altman detailed plans for the company’s GPT-4.5 and GPT-5 AI models in a roadmap published on X on Wednesday.

In the post, Altman also acknowledged that OpenAI’s product lineup has gotten complicated and says that the company wants to do “a much better job” simplifying its offerings. “We hate the model picker as much as you do and want to return to magic unified intelligence,” Altman says.

The company plans to ship GPT-4.5, which he says was called Orion internally, will be OpenAI’s “last non-chain-of-thought model.” The Verge reported on some details about Orion last year.

OPENAI ROADMAP UPDATE FOR GPT-4.5 and GPT-5:

We want to do a better job of sharing our intended roadmap, and a much better job simplifying our product offerings.

We want AI to “just work” for you; we realize how complicated our model and product offerings have gotten.

We hate…

Following GPT 4.5, “a top goal for us is to unify o-series models and GPT-series models by creating systems that can use all our tools, know when to think for a long time or not, and generally be useful for a very wide range of tasks,” Altman says.

With both ChatGPT and OpenAI’s API, the company plans to “release GPT-5 as a system that integrates a lot of our technology, including o3,” Altman says, adding that “we will no longer ship o3 as a standalone model.” OpenAI first teased o3 in December and launched o3-mini in January.

When GPT-5 is available, Altman says that free ChatGPT users will get “unlimited chat access” at “the standard intelligence setting.” Plus subscribers will be able to use GPT-5 at “a higher level of intelligence” and Pro subscribers getting “an even higher level of intelligence.”

Altman didn’t say exactly when GPT-4.5 and GPT-5 might be released, but he did give a vague estimate of “weeks / months.”

This week, Elon Musk offered to buy OpenAI’s nonprofit arm for $97.4 billion, but OpenAI’s board of directors plans to reject the bid.
