Earlier quoted context omitted.
Right, but there's no contamination studies there. I suspect that RLHF data leaked HumanEval into GPT-4. It just seems unlikely to me that GPT-4's coding abilities have improved since March (when 67% was officially reported by OpenAI) given all of the examples and anecdotes about degradation. This is why we use the official numbers.
But the model in OP is fine-tuned by "a proprietary dataset of ~80k high-quality programming problems and solutions". How do we know it's not contaminated by HumanEval too?
> Furthermore, we applied OpenAI's decontamination methodology to our dataset to ensure valid results, and found no contaminated examples.
