name: krea2-txt2img-manual
display_name: KREA 2 — Text to Image (Manual Prompt)
family: krea2
kind: txt2img
description: >-
  KREA 2 (krea2_turbo) text-to-image with a plain prose prompt — a fast,
  ultra-sharp turbo model with strong prompt-following. Runs on native ComfyUI
  krea2 support (CLIPLoader type=krea2) with a Qwen3-VL 4B text encoder and the
  Qwen image VAE, at 8 steps / cfg 1. Standalone single-pipeline graph sliced from
  the KREA2 ULTRA V2 monolith — no group toggles — type your prompt into the MANUAL
  PROMPT node and run. V2 adds the Krea2T-Enhancer model detail-boost patch (ships
  ACTIVE). For Ideogram-style structured JSON / area prompting, use the
  krea2-txt2img-json pack; for the two-pass detail-boost combo, use krea2-combo.

notes:
  - Needs ComfyUI with native KREA 2 support (comfy/text_encoders/krea2.py,
    ComfyUI >= v0.26.0) — the CLIPLoader uses type=krea2.
  - Run the generated installer from your ComfyUI root (folder with custom_nodes/
    and models/).
  - Default diffusion model is krea2_turbo_fp8 (RTX 4000/3000/2000). On RTX 5000
    (Blackwell) swap in krea2_turbo_mxfp8.safetensors for native fp8.
  - One clean pipeline, no group toggles. The JSON-builder branch lives in the
    krea2-txt2img-json pack; the two-pass detail-boost combo is krea2-combo.
  - V2 Krea2T-Enhancer (a MODEL detail-boost patch) ships ACTIVE in the model path
    (PowerLora -> Krea2T-Enhancer -> sampler). Bypass it to compare against the
    un-boosted result.
  - Smart Seed Variance (RBG_Smart_Seed_Variance) ships BYPASSED (optional,
    passthrough in the positive-conditioning loop) — un-bypass to explore
    controlled variations of the same prompt; set its seed mode to "randomize" and
    tune the variance mode/strength widgets.
post_install:
  - Restart ComfyUI (or ComfyUI-Manager -> Install missing custom nodes for any
    node Python deps).
  - Load workflow.json.
