Newest model from OpenAI.
GPT-4 is a large multimodal model (accepting image and text inputs, emitting text outputs) that, while less capable than humans in many real-world scenarios, exhibits human-level performance on various professional and academic benchmarks.
I have this in my ChatGPT+ account and it does produce more reliable outputs in my limited testing.
