Qwen3-4B-Thinking-2507 text encoder

• A fully ready Qwen3-4B-Thinking-2507 build. Compared to vanilla Qwen3-4B, it delivers noticeably better prompt adherence with Z-Image models and avoids common wording misinterpretations. Highly recommended for both inference and Z-Image LoRA training.

• Path: ComfyUI_windows_portable\ComfyUI\models\text_encoders\

• Qwen3-4B-Thinking-2507 USAGE:

  [ANCHOR: who / what exists]
  [ROLE or STATE: what defines them conceptually]
  [ACTION or POSTURE: what they are doing or how they are positioned]
  [RELATIONSHIP: how they relate to space, objects, or viewer]
  [ENVIRONMENT: where this takes place, minimally]
  [INTENT: what the image is meant to communicate]
  [LIGHTING: chosen to support the intent]
  [CAMERA / FRAMING: how the viewer perceives it]
  [STYLE RESTRAINTS: what it should resemble, softly]
  [CONSTRAINTS: what must be avoided]
  
  example:
  a single adult man,
  calm and self-contained rather than expressive,
  standing upright with relaxed posture,
  positioned slightly off-center to create quiet tension,
  inside a simple, uncluttered interior space,
  the focus is on presence and character rather than action,
  soft indirect light so that facial features remain natural,
  eye-level camera, medium framing from the chest up,
  realistic but understated photographic style,
  no exaggerated emotion, no stylization, no dramatic effects
  
  example 2:
  [SUBJECT / ANCHOR],  
  [TRAIT / MOOD / PERSONALITY],  
  [ACTION / POSTURE / STATE],  
  [POSITION / RELATION TO SPACE / COMPOSITION],  
  [ENVIRONMENT / SETTING],  
  [INTENT / WHAT THE IMAGE SHOULD CONVEY],  
  [LIGHTING / ATMOSPHERE],  
  [CAMERA / FRAMING / PERSPECTIVE],  
  [STYLE / ARTISTIC DIRECTION],  
  [FORM CLARITY / SHAPE / TEXTURE / COLOR DIRECTIONS]
  
  example:
  a single adult man,  
  calm and self-contained,  
  standing upright with relaxed posture,  
  positioned slightly off-center to create quiet tension,  
  inside a simple, uncluttered interior space,  
  showing presence and character through posture and expression,  
  soft indirect light to enhance facial features naturally,  
  eye-level camera, medium framing from the chest up,  
  photographic style with subtle tones and understated textures,  
  featuring clear forms, natural proportions, and readable visual composition
  

• You use this inside of your positive prompt; meaning the example part only****_. the explaining part is just for you to understand the layout not the text encoder_

**Please note that Qwen3-4B-Thinking-2507 is just experimental with this model but with right tweaks it can provide great outputs and any trained lora on the vanilla qwen3_4b will not function properly under this encoder so you will need to retrain using this text encoder.
