OpenAI has introduced two new large language model variants, o3 and o4-mini. The company claims that these models are their 'smartest and most capable' to date, but does not provide specific details on what this means in terms of performance or capabilities. Full tool access is available for these models, which could be useful for developers looking to integrate them into their applications. --- Why it matters: These new models may be of interest to researchers and engineers working with large language models, as they represent the latest advancements from OpenAI. The availability of full tool access could also make it easier for developers to experiment with these models in their own projects. Source: https://openai.com/index/introducing-o3-and-o4-mini
