MOSTIK tops ARC-AGI leaderboard by piping frontier-model reasoning into small models via latent space
SimplyAnnisa · x · 2026-09-03
A team of 12 PhDs working for four months, MOSTIK claims first place on the ARC-AGI leaderboard. Its core idea: a frontier model only needs to do the reasoning — a small model on your own infrastructure converts it into the final answer.
- Models communicate directly in latent space: hidden states pass from the frontier model into the small one via a protocol, with no text in between
- No model-specific fine-tuning required, and different model families can be mixed
- If it scales reliably, this could dramatically cut compute costs without sacrificing reasoning quality
Competition details remain under wraps while the contest is still running.
