OpenAI GPT-4.5: OpenAI has revealed its GPT 4.5 model as a research preview. OpenAI claims that this model advances pre-training and post-training by improving upon pattern recognition, generating insights and cutting down on hallucinations.
OpenAI asserts that GPT-4.5 enhances unsupervised learning, boosting its intuition and knowledge accuracy. The model is expected to be more reliable across various topics, having been trained on Microsoft Azure AI supercomputers. However, it lacks reasoning-based responses, which are features of OpenAI's o1 and other models.

How can you access it?
ChatGPT Pro users now have access to GPT-4.5, and gradually Team, Plus, Enterprise and Edu users will also get to use it. It will allow users to interact through texts, file and image uploads, and search-based access to the most recent information. Although multimodal features are still missing like voice mode, video and screen sharing.

“GPT‑4.5 has access to the latest up-to-date information with search, supports file and image uploads, and can use Canvas to work on writing and code. However, GPT‑4.5 does not currently support multimodal features like Voice Mode, video, and screen sharing in ChatGPT. In the future, we will work to simplify the user experience so AI “just works” for you,” the company stated in its blog.
Additionally, OpenAI has stressed the importance of safety, explaining that the model went through reinforcement learning with human feedback and was fine-tuned under supervision. Before it was rolled out, safety checks were conducted, and the results were documented in a system card that came with it.
Even though ChatGPT-4.5 is available to developers through the API, OpenAI has pointed out that this is a more compute-intensive model and costs more to function than the GPT-4o. Based on user feedback and adoption, the company is evaluating whether to continue offering long-term API access.
