Prior Labs' RelArena-alpha release standardizes those conditions on RelBench v1 tasks, including how methods are tuned.
Its TabPFN-Rel component automates a familiar approach: join and summarize related tables into one table, then apply a predictive model. A separate interface lets users specify prediction tasks on their own databases. Together, these tools connect benchmarkA standard public test set for comparing AI models — the shared scoreboards behind every "model X beats model Y" claim.Full definition → comparisons to experiments on business data. Prior Labs explicitly describes the release as alpha software for researchers and early adopters.

eval — A repeatable test for AI quality — a set of tasks plus scoring — used the way software teams use test suites, because model output is too variable to judge by eyeballing.
benchmark — A standard public test set for comparing AI models — the shared scoreboards behind every "model X beats model Y" claim.
agent harness — The scaffolding around a model that turns it into a working agent — the loop, the tools it can call, and the rules for when to stop.
