Show HN: ModelKombat – Arena-style battles for coding models

I'm Vivek, co-founder/CEO of HackerRank (YC S11); You may know us as a hiring tool for developers/companies.

Over the years, we have built up deep expertise in generating programming challenges, and we are now using that to make coding models better.

Our first launch is Model Kombat -- an arena where you can directly compare anonymized coding models, side by side, on real problems.

* Pick an arena (Java, Python, etc.) * Each battle has 3 rounds: see the problem + two model outputs -> vote on which you’d actually prefer * Leaderboards + problem statements are updated weekly.

We already have 400+ challenges live, and our goal is to evolve toward real-world, multi-file challenges and robust tooling for coding model evaluation.

We’d love your feedback.
