The curator’s take
TUMIX is an ensemble recipe for reasoning that mixes text, code execution, and web search, running 15 diverse agents in parallel and passing intermediate answers across rounds. An LLM-judge controls early stopping, giving up to +3.55% accuracy gains over strong tool-augmented baselines on HLE, GPQA-Diamond, and AIME 24/25 while cutting inference cost by ~50%.
