Expectations for OpenAI's next-generation model, GPT-5, are soaring. According to industry sources, GPT-5 is expected to adopt a new architecture that significantly improves upon the existing Transformer architecture. The most notable change is the introduction of a 'Reasoning Engine.' This is expected to significantly enhance logical reasoning and planning capabilities, moving beyond simple pattern matching. Furthermore, enhanced omni-modal processing capabilities will enable it to comprehensively understand and generate text, images, audio, and video. This is regarded as a significant step towards AGI (Artificial General Intelligence).
