Arena.ai(@arena):We analyzed how similar model responses were across 30,086 Arena battles. Models shared 43% of their ideas on average. We might expect that models from the same lab, or country, would show greater conceptual overlap. But the results don’t consistently support that. Claude Fable 5 illustrates this pattern: its closest conceptual match was neither Opus nor Sonnet. Which model came closest, along with the broader findings, may surprise you. Check out the full article from @DawidGalarowicz and @petergostev below.
