Researchers have developed a technique called vocabulary dropout to address diversity collapse in co-evolutionary language model training. This method involves applying a random mask to the proposer model's output logits, preventing it from generating repetitive problems. Experiments with Qwen3-4B and Qwen3-8B models on mathematical reasoning tasks showed that vocabulary dropout maintained proposer diversity and led to significant solver improvements, particularly on challenging benchmarks.
