ComfyUI-Flux2KontextConditioner
Advanced conditioning node for Flux2 Klein Kontext image editing workflows. Encodes up to 3 reference images via the Flux2 VAE and attaches them as reference latents for Kontext attention. Text is encoded through the Qwen3-8B LLM-based text encoder with optional instruct prompt wrapping. Supports per-image strength and resolution control, VAE tiling for high-resolution encoding, and bakes the Flux2 guidance scale directly into the conditioning.
