pretty wild versioning that GPT 4.1 is newer and better in many regards than GPT 4.5.
it's worse on nearly every benchmark
OpenAI themselves said
> One last note: we’ll also begin deprecating GPT-4.5 Preview in the API today as GPT-4.1 offers improved or similar performance on many key capabilities at lower latency and cost. GPT-4.5 in the API will be turned off in three months, on July 14, to allow time to transition (and GPT 4.5 will continue to be available in ChatGPT).
no? it's better on AIME '24, Multilingual MMLU, SWE-bench, Aider’s polyglot, MMMU, ComplexFuncBench
and it ties on a lot of benchmarks
look at all the graphs in the article
I think they're doing it deliberately at this point
Tomorrow they are releasing the open source GPT-1.4 model :P
