Hey com2kid - if you're still there, we did end up adding boxplots to show variance. Can be seen on the models page https://artificialanalysis.ai/models and on each models page where you view hosts by clicking one of the models. They are toward the end of the page under 'Detailed performance metrics'
Your latency numbers for OpenAI (and Azure's equivalents) seem really high, I run time to first token tests and I see much better numbers!
(Also are those numbers average, p50, p99, etc? I'd honestly expect a box plot to really see what is going on!)
