OpenAI has expanded its o1 AI models to enterprise and education sectors, introducing o1-mini and o1-preview. The o1 model, which includes advanced reasoning capabilities, has been evaluated in a new research paper. The study, conducted by researchers from Arizona State University, indicates that while o1 outperforms other language models on the PlanBench planning benchmark, it still faces challenges in accuracy, efficiency, and reliability. The paper also highlights that domain-independent planners like Fast Downward can solve all instances of Mystery Blocksworld, whereas LLMs struggle. Additionally, OpenAI has increased access and rate limits for developers, allowing up to 1000 requests per minute for o1-preview and 5000 for o1-mini. This expansion comes as OpenAI competes with Anthropic on the enterprise front.
