OMEGA-HET-expandA — matched HET-vs-HOM SFT (equal-size) Matched supervised-fine-tuning data for the OMEGA diversity experiment: for each math prompt, reasoning trajectories are sampled two ways and only prompts solved (math-verified correct) in both conditions are kept (matched HOM∩HET = 3,219 prompts), so HET and HOM are directly comparable. HET (heterogeneous): true token-level continuation across a 3×32B roster (Qwen3-32B + DeepSeek-R1-Distill-Qwen-32B +… See the full description on the dataset page: https://huggingface.co/datasets/shizhuo2/omega-het-expandA-sft.
