The o1 series of models are trained with reinforcement learning to perform complex reasoning. o1 models think before they answer, producing a long internal chain of thought before responding to the user. Learn about the capabilities of o1 models in our reasoning guide.
There are two model types available today:
o1: reasoning model designed to solve hard problems across domains
o1-mini: fast and affordable reasoning model for specialized tasks
The latest o1 model supports both text and image inputs, and produces text outputs (including Structured Outputs). o1-mini currently only supports text inputs and outputs.
One of the best ChatGPT updates we've seen in a long time, finally a model with 100k output and 200k input context window This update is INSANE for developers and content creators alike - allowing for a fully reasoning model to now be able to have 200k input tokens and 100k output tokens is completely nuts I've been waiting for something like this for a while now, as in certain cases (like content generators), a model like ChatGPT's o1 can be vastly superior to something like ChatGPT 4o mini or ChatGPT 4o - and with a huge context window and output limit length that’s going to open up endless possibilities—both for scaling projects and fine-tuning content output. I’m talking improved performance, more in-depth reasoning, and the ability to handle massive amounts of text input at once
