 # ComfyUI-InferenceTimeScaling
 
-A ComfyUI extension implementing "Inference-time scaling for diffusion models beyond scaling denoising steps" ([Ma et al., 2025](https://arxiv.org/abs/2501.09732)). This extension provides advanced inference-time optimization techniques to improve image generation quality through random search and zero-order optimization algorithms, along with an ensemble verification system.

+## Current Limitations
+
+- Single latent processing only (batch size = 1) - performance limitation
+- Sequential verification (one image-text pair at a time) - speed bottleneck
+
+## Future Work
+
+- [ ] Add batch processing support for image generation (performance optimization)
+- [ ] Implement batched verification for multiple image-text pairs (speed optimization)
