ComfyUI Node
JR H3 Unified Acceleration v2 (Experimental)
Experimental H3 sparse backend selection. Start from a MODEL without attention patches. Legacy is the conservative default; select core to evaluate the native chunked producer. Auto may choose legacy before sampling, never after a CUDA/runtime failure. Core currently excludes TST, tau_profile, custom legacy quantization and allow_compile.
