Ultra benchmarked around the original release of GPT-4, not the current model. My understanding is that was fairly accurate — it's close to current GPT-4 but not quite equal. However, close-to-GPT-4 but 4x cheaper and 10x context length would be very impressive and IMO useful.
No, it benchmarked around the original release of GPT-4 given 32 attempts versus GPT-4's 5.
