Description:

The full o1 model is released to the public, replacing the 'o1 preview' model. This reasoning model, compared to the preview version, is 50% faster, makes less mistakes, and is multimodal (accepting image inputs). OpenAI also announces a Pro subscription plan ($200/month) which gives ChatGPT users unlimited usage of its top models, as well to a slightly more powerful version of the o1 model, named o1 Pro.
