Tool introduction 2 min read ChatQT Team

What is Flux?

Flux is the name of a set of text-to-image models developed by Black Forest Labs . The main focus is on detail, natural light and more acceptable faces and hands compared to older Stable Diffusion generations. It has become a popular choice for product photos, portraits and advertising scenes.

Flux versions

Flux Pro

The highest quality; suitable for commercial output and access via API.

Flux Dev

Open weights for research and local execution on a personal GPU.

Flux Schnell

Fast generation at preview quality; good for ideation and prompt testing.

Strengths

  • Realism in product photos and portraits
  • Text inside images better than many older SD models
  • Prompt adherence stronger
  • Anatomy and hands improved over SD 1.5

Flux vs DALL-E 3 and Midjourney

  • Flux: realism and technical detail
  • DALL-E: integration with ChatGPT and conversational editing
  • Midjourney: artistic, stylized aesthetics

The choice depends on whether you want a catalog photo or a creative poster.

Prompt tips

Prompt
Ultra realistic product photo, ceramic coffee mug,
marble surface, soft window light, 85mm, 8K, commercial.
Prompt
A hyper-realistic product photo, a ceramic coffee mug, a marble surface, soft window light, an 85mm lens, advertising quality.

Unlike SD 1.5, a long negative prompt is often unnecessary; Flux understands instructions better.

Chat + image pipeline

  1. In the Chat Expand the creative brief.
  2. In image generation, choose Flux Pro.
  3. Refine with a new prompt: 'warmer, add coffee steam'.

Local execution (Dev)

Flux Dev can run on a personal system; a GPU with at least 12 GB of VRAM is usually recommended. If you don't have the hardware, ChatQT's cloud version is a practical alternative.

Common uses

  • Product photos for online stores and catalogs
  • Portraits and site headers with natural light
  • Advertising scenes and packaging mockups
  • Idea testing before a studio shoot (budget savings)

For commercial content, always generate several versions and pick the best for print or web; AI sometimes gets small details wrong (text on packaging, a finger). A final review in an image editor is still recommended.

Conclusion

Flux is top-tier for realistic images. ChatQT provides an accessible gateway for users in Iran. To start, sign-up accept it.
