OpenAI releases ‘largest, most knowledgable’ model GPT-4.5 with reduced hallucinations and high API price
The API pricing appears shockingly high, costing developers $75 and $180 for 1 million tokens in and out, respectively.
This training regimen apparently helped GPT-4.5 learn to produce more natural and intuitive interactions, follow user intent more accurately, and demonstrate greater emotional intelligence. It supports key features like function calling, structured outputs, streaming, system messages, and image inputs, making it a versatile tool for various AI-driven applications. The release of GPT-4.5 has sparked mixed reactions from AI researchers and tech enthusiasts on the social network X, particularly after a version of the model’s “System Card” (a technical document outlining its training and evaluations) leaked earlier (included below at the bottom of this article), revealing a variety of benchmark results ahead of the official announcement.
