nowThis paper directly addresses the common belief in the community that on-policy rollouts are the fundamental ingredient separating RL from SFT. Let's look at the HTML version to extract the concrete measurements and findings.

Oh et al. (Meta Superintelligence Labs, arXiv:2610.01509) evaluate 14 base/post-trained LLM pairs on agentic benchmarks (BFCL, WebShop, ACEBench): post-training trades coverage for single-shot accuracy by bimodalizing task outcomes, shrinking 'pass-given-compute'. On WebShop, gemma-4-31B base with a light harness achieves >85% pass@128 vs 56% for its post-trained counterpart, with crossover budget dropping to k*≈3 at 31B scale.

Karan, Chen & Du (arXiv:2610.02140) propose Projection Sampling via block MCMC to boost off-policy SFT data towards base model likelihood; on Qwen2.5-3B, Sampling SFT reaches 49.5% on MATH(3-5) vs 24.3% vanilla SFT and 45.7% GRPO, while retaining prior capabilities (GSM8K at 78.2% vs 45.5% vanilla SFT).
