OpenAI has introduced its new 'o1' series of reasoning models, designed to tackle complex problems in science, coding, and mathematics with human-like reasoning abilities. The first model, 'OpenAI o1-preview,' is now available in ChatGPT and through its API, showcasing significant improvements over previous models, such as outperforming its predecessors in coding competitions and academic benchmarks. However, the model is still in its early stages and lacks some features of current ChatGPT versions, like web browsing and file uploads. OpenAI emphasizes the model's safety, with improved resistance to jailbreaking attempts. This launch comes as OpenAI seeks to raise $6.5 billion in funding, potentially elevating its valuation to $150 billion. The new model, internally known as 'Strawberry,' reflects OpenAI's ongoing efforts to lead in the competitive AI market.
