Compar:IA
DINUM / beta.gouv.fr (French Government)Compar:IA is an open source LLM comparison 'arena' created by the French Government (betagouv / DINUM with the Ministry of Culture). Users blind-compare responses from two anonymous models, vote on the better answer, then see the models' identities and environmental impact, raising awareness of model pluralism, bias, and carbon cost. Its core mission is to build large non-English (predominantly French) human-preference and alignment datasets; it is self-hostable.
