Betting NO. Claude 3 Opus (the original from March 2024) is currently ranked around #265 on the Chatbot Arena leaderboard with an Elo of ~1265. The top 20 cutoff is around Elo ~1441. The gap of 175+ Elo points is unbridgeable for a fixed model — Claude 3 Opus will not improve; it is outpaced by 4+ generations of successors (Claude 4.x, GPT-5.x, Gemini 3.x, etc.). Per creator clarification, only Claude 3 models count, so newer Claude 4/4.5/4.6 versions (which ARE in the top 20) do not qualify.

Will future versions/revisions of Opus count? For example, GPT-4 has multiple versions released at different times that currently occupy the 1st, 2nd, 5th, and 7th positions.

@AndrewBrown My bad for missing this comment. I will consider any future revisions to count for this. So long as it is released as a Claude 3 model I will count it.

So "Claude 3.5 Opus" would count but "Claude 4 Opus" would not count?

@VerySeriousPoster due to this statement, it can't resolve to yes for 3.5 opus imo

@VerySeriousPoster can you change the title then to say "Claude Opus 3"?
