OPENAI UNVEILS GPT-4.5 ‘ORION,' ITS LARGEST AI MODEL YET

Summary from the TLDR newsletter

OpenAI is now rolling out GPT-4.5 to ChatGPT Pro subscribers and developers on paid tiers of the company's API. Other users should get the model sometime next week. GPT-4.5 is so expensive to run that OpenAI is evaluating whether to continue serving the model on its API in the long term. It currently costs $75 for every million input tokens and $150 for every million output tokens. This article looks at how the new model compares to OpenAI's other offerings.
