The GPT next-generation model roadmap is moving in the direction of resolving the inconvenience of having to select multiple models and automatically providing optimal results based on the user’s prompt content. According to this roadmap, there are two main models: first, GPT 4.5 (aka Orion model), and then Unified GPT 5, which integrates all functions.

──────────────────────────────

1. Key Features by Model

[① GPT 4.5 – Orion Model]
• Provides further upgraded performance compared to the currently used GPT models.
• Classified as a 'thinking' model, it maintains the existing fast response method while allowing for more sophisticated task processing.
• Even if the user does not directly select a model, the system internally generates answers that best fit the 'thinking method' according to the complexity of the prompt.
• It will be released first, allowing users to experience the latest technology.

[② GPT 5 – Unified Model]
• A form that integrates all the functions of existing models, including GPT 4.5.
• When a user enters a prompt, the AI internal algorithm determines which model (e.g., GPT 51, O3, etc.) to use and automatically provides the best results.
• The desired performance level varies depending on the user's subscription plan (the level of 'brain' of artificial intelligence provided internally is differentiated according to Free, GPT Plus, and GPT Pro).
• Not only text prompts but also voice function, canvas function, search, deep research function, and other various functions will be upgraded and provided together.

2. Differentiation by Subscription Plan

• Free users: Will receive the basic functions and performance of GPT 5.
• GPT Plus Subscribers: In addition to the above basic functions, improved performance artificial intelligence operates in the background to expect more sophisticated results.
• GPT Pro Subscribers: An environment is provided to utilize the most outstanding artificial intelligence performance and additional functions (e.g., deep research, file/image upload, etc.).

3. Additional Updates

• Previously, only GPT 4.5 could upload files or images, but since the recent update, GPT 51 and O3 mini models also support this function.
• In particular, AI's automatic code generation function is provided for coding or complex tasks, which is expected to be of great help in website creation or service development.
• Users have also given positive reviews, saying that the limit restriction has been eased due to recent updates, allowing for more utilization than before.

4. Release Schedule and Future Development Direction

• GPT 4.5 is likely to be released before summer, and the integrated GPT 5 model is expected to be released around the fall.
• A variety of AI functions are combined for precise user-customized task processing, which is expected to bring about a revolution in how artificial intelligence is used in the future.
• We will continue to update the news and usage tips quickly, so those who are interested should pay attention.

As such, the next-generation roadmap of Open AI focuses on eliminating the complex model selection process from the user's perspective and providing a powerful artificial intelligence platform. Users will now be able to get only the desired results without worrying about model selection.
