SCHEMA

Schema is a harness that makes frontier models play like physicists. It can help frontier models achieve 99% on ARC-AGI-3 Public. ARC‑AGI‑3 gives agents a game environment without an explanation of what it is seeing. Schema makes agents write each game's mechanism as an executable program, test it against reality, and plan inside it. It controls how observations are turned into a working model of a game, how predictions are tested against the interaction history, and how plans are executed and revised.

THE BEST MODEL ROUTING IS TASK SPECIFIC

Model routing is a hot topic because nobody wants to pay frontier prices for every token. The best routing is deeply task-specific. The more narrowly you focus on a single workflow, the more alpha there is to exploit in terms of both accuracy and cost. The problem is figuring out which model clears the bar for which task, subject to cost/latency constraints.
