> it seems to me like they nerfed the regular free ai model ... My main takeaway from the article was more about the unsustainable business model due to a massive cash burn rate. To wit: OpenAI’s models and products — and we'll get into their utility in a bit — are deeply unprofitable to operate, with the Information reporting that OpenAI is paying Microsoft an estimated $4 billion in 2024 to power ChatGPT and its underlying models, and that's with Microsoft giving it a discounted $1.30-per-GPU-an-hour cost, as opposed to the regular $3.40 to $4 that other customers pay. This means that OpenAI would likely be burning more like $6 billion a year on server costs if it wasn’t so deeply wedded to Microsoft — and that's before you get into costs like staffing ($1.5 billion a year), and, as I've discussed, training costs that are currently $3 billion for the year and will almost certainly increase. Whether or not the "free model" is better or worse than the "o1 model" is moot IMHO.
