Show HN: MetaArena – Compare & Rank 5,353 Meta Global AI Hackathon Projects
Hey HN! Recently Meta wrapped up their Global Developer Hackathon ( https://dev.meta.ai/events/global-hackathon ) which had a $1M prize pool (!!): 34K developers applied, 20K accepted, and over 5K projects were submitted. With this crazy volume, it was infeasible to rank or even shortlist the best projects with human review. On the other hand, AI scoring against a rubric led to disappointing results.

Who is affected
Identify the existing workflow this change affects before recommending an upgrade. Launch attention does not establish improvement; an API, pricing or availability change may instead create migration work.
Missing comparison points
Missing checks: old versus new behavior, affected plans and regions, availability date, compatibility, rollback path and cost under the same workload.
Migration check
Save the release or policy notice, run the same task on the old and new option, and compare outputs and the full bill. For retirement notices, verify the deadline before scheduling migration.
