We just launch a new Category "Exclude Refusal" based on a keyword filter to identify whether model refuses to answer user question (e.g. "sorry, I cannot answer...") We filtered out ~7% (40K) votes. Result: 1. All Claude models go up, despite still 1>2🤔 2. Some open models

One thought about the @lmsysorg leaderboard: It quite heavily favours models that lack any kind of refusal system. I think this is a big part of why Claude1/2 scored so poorly - you're always going to lose the duel if you refuse to participate!
