HIGHLIGHTS
OpenAI has officially introduced the GPT-4.5 model as a part of its research preview initiative. This new iteration signifies an evolution in both pre-training and post-training processes, elevating the model’s capabilities in pattern recognition, insight generation, and hallucination reduction.
According to OpenAI, GPT-4.5 enhances unsupervised learning, which in turn augments the model’s intuition and accuracy in knowledge retention. The architecture of this model has been designed to be more reliable across various topics, having been trained on the advanced Microsoft Azure AI supercomputers. It is important to note, however, that GPT-4.5 does not incorporate reasoning-based responses, which is a characteristic shared with its predecessors, including GPT-4o.
For those who hold a subscription with ChatGPT Pro, access to GPT-4.5 is now live. Furthermore, users subscribed to Plus, Team, Enterprise, and Edu plans will receive access gradually in upcoming releases. The model supports a range of interactions, including text-based conversations, file uploads, and image uploads. However, features such as voice interaction, video capabilities, and screen sharing are still not integrated at this time.

OpenAI elaborated on the features of GPT-4.5, stating, “The model has access to the latest information through search capabilities, supports uploads of both files and images, and utilizes a canvas for collaborative writing and coding tasks. However, it presently lacks multimodal features such as Voice Mode, video sharing, and screen sharing within the ChatGPT environment. Our goal moving forward is to streamline the user experience, ensuring that AI functions seamlessly for you,” as mentioned in their official blog.
Moreover, OpenAI has emphasized their commitment to safety with this new model. They have implemented reinforcement learning driven by human feedback along with supervised fine-tuning measures. Before the model’s official deployment, comprehensive safety assessments were carried out, and the findings were documented in a system card that accompanied the rollout.

While GPT-4.5 is being made accessible to developers through an API, it is essential to understand that this model is significantly compute-intensive, incurring higher operational costs compared to GPT-4o. OpenAI is carefully evaluating user feedback and the rate of adoption as a factor in deciding on the long-term availability of API access.
