    "body_text": "All-atom protein predictors can spend about 200 denoising steps producing a structure. Blitz uses a geometric noise schedule and multistep consistency training to compress that process to eight steps, then applies physical steering and target-free candidate selection at inference. Under one common evaluation protocol, the authors report that distilled AlphaFold 3 and Boltz-2 models retained teacher-level structural accuracy; AF3-Blitz exceeded the tested few-step baselines and its teacher on several metrics. The comparisons cover structure, interfaces, ligands and stereochemistry, but they remain computational benchmarks rather than experimental confirmation of molecular behavior. The result narrows a costly iterative stage without claiming that eight steps settle every biological question.",
