OpenAI has unveiled its roadmap for the release of its next-generation AI models, GPT-4.5 and GPT-5. According to CEO Sam Altman, GPT-4.5, codenamed 'Orion,' will be launched in the coming weeks as the company's last non-chain-of-thought model, while GPT-5 is expected to follow within months. A major shift in OpenAI's strategy includes the elimination of the 'model picker' feature, aiming to simplify user experience with a unified AI model. This unified system will integrate OpenAI's various models, adapting to different tasks automatically. Additionally, GPT-5 will reportedly be available to free-tier ChatGPT users with standard intelligence settings, with advanced features accessible through paid subscriptions. The roadmap also highlights OpenAI's focus on enhancing usability and accessibility for a wide range of applications. The announcement comes amid growing competition in the AI space, including challenges from emerging models like DeepSeek, which offers a low-cost advantage.
