OpenAI releases GPT-4.5 claiming 10X efficiency over GPT-4, but says it’s ‘not a frontier model’


The API pricing appears shockingly high, costing developers $75 and $180 for 1 million tokens in and out, respectively.

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 the System Card leak revealed benchmark results ahead of the official announcement. These discussions underscore a broader debate in AI: Should progress be measured purely in benchmarks, or do qualitative improvements in reasoning, creativity, and human-like interactions hold greater value?
