Furthermore, OpenAI stated that the 5.5 model performs on par with 5.4 in terms of Token speed. If used specifically for coding (CodeX), the speed is even better, providing a superior experience without sacrificing efficiency.

Currently, the API has not yet been rolled out, but OpenAI plans to price the base model at $5 per 1 million input tokens and $30 per 1 million output tokens, featuring a context window of 1 million tokens. The Pro version will cost $30 per 1 million input tokens and a staggering $180 per 1 million output tokens.
