OpenAI has introduced two major updates to ChatGPT. The first update is the release of the full version of the 01 model, which is a reasoning model previously available only in a limited preview. This model, known as Project Strawberry, has been improved for speed and capability, making it suitable for advanced reasoning tasks. Users with any paid ChatGPT plan can now access this model. The second update is the introduction of a new subscription tier called ChatGPT Pro, priced at $200 per month. This plan offers unlimited access to GPT-4.0 and the new 01 model, making it ideal for power users who require extensive use of these advanced features. The 01 Pro mode, an even more advanced version of the 01 model, is also available, offering superior performance for complex tasks such as science, math, and coding. Additionally, the new 01 model includes vision capabilities and image uploads, with future updates expected to include web browsing.
