We're adding RAR-b with & without instructions as two leaderboard tabs under Retrieval with @gowitheflow-1998. Naming-wise it is confusing to have these and also the Retrieval w/ Instructions tab. In general, that tab name is a bit confusing as many models use instructions for retrieval tasks in the regular retrieval tab. I don't have an idea yet for how to make it better though, but in case someone does let us know! 😁
