OpenAI has embraced the festive spirit with its "12 days of OpenAI" event, releasing something new every weekday between now and December 20. In CEO Sam Altman's own words, the company will "have a livestream with a launch or demo, some big ones and some stocking stuffers."
So far we've seen the launch of the o1 reasoning model and a new o1 Pro model behind a new $200 per month ChatGPT Pro subscription. Finally, we got something for research scientists on Friday in the form of reinforcement fine-tuning of models.
