You upload a zip of ten or more images or clips, the trainer fine-tunes only the low-noise transformer of the Wan 2.2 A14B model, and out comes a .safetensors LoRA file you plug into the inference endpoint. At the stated rates, the cheapest possible training run works out to forty cents.

MSR is a test-time approach that externalizes diversity into an explicit, corpus-derived sampling procedure, using the generative model purely as a conditional renderer of a sampled configuration. The authors argue that modern generative models struggle to sample diversely even when explicitly instructed to, and report that MSR improves both the diversity of generated outputs and their alignment with corpus distributions. They evaluated it across weather report generation, user simulation, webpage design, text-to-image generation, and agent-generated 3D assets. It is a preprint, so the results are the authors' own and should be read that way — but the direction is clear: steering is being pushed out of training and into the sampling step.",
