OpenAI’s Next Moves: GPT-4.5 Incoming, GPT-5 to Change the Game

Sam Altman on X has tweeted about openai’s  roadmap for the upcoming GPT-4.5 and GPT-5 models, aiming to simplify its product offerings and enhance user experience. CEO Sam Altman emphasized the company’s commitment to making AI more intuitive, acknowledging the current complexity of their models.

GPT-4.5: The Final Non-Chain-of-Thought Model

The next release, GPT-4.5, internally named “Orion,” will be OpenAI’s last model without chain-of-thought capabilities. This development marks a shift towards more advanced reasoning in future models.

GPT-5: Unifying AI Capabilities

Following GPT-4.5, OpenAI plans to merge its o-series and GPT-series models into GPT-5. This unified system will intelligently determine the depth of reasoning required for various tasks and seamlessly integrate tools like voice, canvas, search, and deep research. Notably, GPT-5 will incorporate the capabilities of the o3 model, which will no longer be available as a standalone product.

Enhanced Access Across User Tiers

Upon its release, GPT-5 will be accessible to all ChatGPT users:

• Free Tier: Unlimited chat access at the standard intelligence setting, subject to usage policies.

• Plus Subscribers: Access to GPT-5 at a higher intelligence level.

• Pro Subscribers: Access to GPT-5 at the highest intelligence level, with additional features.

These developments reflect OpenAI’s dedication to delivering a more streamlined and powerful AI experience for its users.
