The solver takes the LLB graph and executes it. Each vertex in the DAG is content-addressed, so if you’ve already built a particular step with the same inputs, BuildKit skips it entirely. This is why BuildKit is fast: it doesn’t just cache layers linearly like the old Docker builder. It caches at the operation level across the entire graph, and it can execute independent branches in parallel.
Surprisingly, as a smaller model it performed better than Gemini 3 Pro. It found some valid assignments for SAT formulas, but has the same issue of making up assignments for UNSAT formulas.
