OpenAI Unveils Plans for GPT-4.5 and GPT-5: More Developments Coming Soon | ChatGPT login | ChatGPT app | OpenAI Login | Turtles AI

OpenAI updates the roadmap for its AI models, announcing GPT-4.5 “Orion” as the latest version without a thought chain and anticipating GPT-5 as a unified system with new advanced capabilities. Significant changes also for ChatGPT and the API.

Key points:

• GPT-4.5 “Orion” will be the last iteration without advanced reasoning.
• GPT-5 will integrate GPT and O-series technologies for greater versatility.
• Changes to ChatGPT with free access to GPT-5 in the basic version and advanced options for subscribers.
• Simplification of the OpenAI offering by eliminating manual model selection for a more intuitive experience.

OpenAI has released its development plan for future evolutions of its AI, outlining next steps toward more advanced integration of language models. The Sam Altman-led company is working on a significant optimization of its product range, with the goal of making the user experience smoother and more intuitive by eliminating the need to manually select the most suitable model. In this context, GPT-4.5, internally called “Orion,” represents a crucial transition point: it will be the last version that does not implement chain-of-thought reasoning, a feature that will allow future models to decide for themselves the depth of processing needed for each request.

The next step will be the merging of the GPT and O-series models, thus unifying the computational capabilities and reasoning frameworks. This evolution will culminate in the release of GPT-5, a system that will absorb the o3 model and overcome the current fragmentation of the OpenAI ecosystem. With GPT-5, the company aims to offer a more adaptive intelligence, capable of autonomously selecting the most suitable tools for each task, without the user having to intervene in the choice of model.

In parallel, OpenAI is reviewing the accessibility of its models through ChatGPT and the API. Users of the free version of ChatGPT will be able to take advantage of GPT-5 with a standard level of intelligence, while Plus and Pro subscribers will have access to more advanced modes, featuring extended functionality such as in-depth search, voice interaction, and the use of visual tools. The intent is to provide a more uniform and scalable user experience, offering diversified options based on users’ needs.

Despite the enthusiasm for these developments, OpenAI has not provided firm dates for the release of GPT-4.5 and GPT-5, merely indicating a time horizon of “weeks or months.” The evolution of artificial intelligence continues to be the focus of global attention, with competitors accelerating in the race for innovation and growing discussions about regulations and ethical implications.

In this constantly changing scenario, OpenAI is positioned as a key player, poised to redefine the AI paradigm with its new solutions.
