overlord_sid85 · reddit · 2026-09-03
A new open-source AST-based prompt parser for ComfyUI replaces regex nodes and wordlist files with features like advanced wildcards (tag weights, number ranges, skip chances), inline mute (//) and solo (!) controls, inline negative extraction (-tag), deterministic seeds, a syntax checker, and a combination counter. Compatible with SDXL weights and inline LoRAs; the author's example prompt yields over 385 quadrillion combinations.
