  "title": "Discriminative Score Function: Turning Pretrained Models into Functional Generative Priors",
  "summary": "DSF replaces diffusion-style generative models or real calibration data by deriving a training-free image-space score field from the loss gradients of an existing pretrained discriminative model, usable for synthesis, editing, inpainting, and zero-shot quantization calibration. It costs only gradient computations through an already-deployed model, but sampling is an iterative gradient-ascent procedure with per-sample latency, and image fidelity is unlikely to match dedicated generative models. It can fail when the discriminative model's implicit manifold trace is weak or task-narrow, producing calibration samples whose distribution mismatch degrades quantized-model accuracy on real data.",
  "rationale": "The only production-relevant claim for a constrained team is data-free PTQ calibration, which is cheap to validate against a labeled holdout but has no quantified gain and uncertain sample fidelity, so it warrants a targeted trial rather than adoption.",
