Introducing GPT-4.5 - hallucinations down, accuracy up, non-reasoning. Rolling out to pro + api. Doesn’t look like anyone will be coding with it any time soon with this type of api pricing:

Input: $75.00 / 1M tokens
Cached input: $37.50 / 1M tokens
Output: $150.00 / 1M tokens

And then in a tweet from sama:

this isn’t a reasoning model and won’t crush benchmarks. it’s a different kind of intelligence and there’s a magic to it i haven’t felt before. really excited for people to try it!
