During August 2025, Seonghun Son integrated the DPM++ 2M SDE Heun sampler into the comfyanonymous/ComfyUI repository, expanding the platform’s diffusion model sampling capabilities. He developed and exposed new Python-based APIs for both CPU and GPU sampling, enabling users to select the new sampler through an updated registry and UI. This work focused on code integration and sampling methods, providing more flexible and efficient experimentation for end users. By aligning changes with the project’s collaborative workflow and maintaining stability, Seonghun delivered a feature that enhances user control over model sampling without introducing new bugs during the development period.

Aug 1, 2025August 2025 monthly summary for comfyanonymous/ComfyUI. Focused on expanding diffusion sampling capabilities by delivering a new sampler integration, exposing APIs, and updating the sampler registry to enable broader user options. What was delivered: - Integrated DPM++ 2M SDE Heun sampler into ComfyUI. Exposed new sampling functions: sample_dpmpp_2m_sde_heun and sample_dpmpp_2m_sde_heun_gpu. - Updated KSAMPLER_NAMES to include the new samplers, enabling selection in the UI and more flexible experimentation with diffusion models. - Aligned changes with commit 3aad339b63f03e17dc6ebae035b90afc2fefb627 ("Add DPM++ 2M SDE Heun (RES) sampler (#9542)"). Impact: - Expands diffusion sampling capabilities, providing higher-quality options and GPU-accelerated paths for faster iteration and deployment. - Improves user control and configurability for model sampling workflows, potentially reducing time-to-value for end users. Major bugs fixed: - None reported this month; effort concentrated on feature delivery and stability of the new sampler path. Technologies/skills demonstrated: - Python-based sampler integration, API exposure (GPU and CPU variants), Git-based collaboration, and repository maintenance for sampler extensions.
