Our Verdict
Flux wins
Flux wins. Significantly better photorealism and text rendering out-of-the-box compared to base Stable Diffusion models.
✓ Winner
Flux
Free (Schnell local) | Pro from $12/mo
Black Forest Labs' open-source image model that shocked the AI world with Midjourney-rivalling photorealism. Schnell (fast) version is free to run locally. Best open-source image quality.
Strengths
- Best prompt adherence of the three — spatial relationships and counts come out right
- Only model with genuinely open weights (Dev, Schnell) for self-hosting/fine-tuning
- Most reliable text-in-image rendering for packaging, UI mockups, memes
Could be better
- Pro tier is closed-weight and API-metered like any SaaS model
- Dev license blocks commercial use without a paid BFL license
- Default aesthetic is flatter/less painterly than Midjourney out of the box
Stable Diffusion
Free (local/cloud) | Pro from $9/mo
The most popular open-source image model. Can run locally for free on any decent GPU. SDXL produces high-quality images with infinite customization via custom models and LoRAs.
Strengths
- Open-source and 100% free for local run
- Vast ecosystem of custom models, LoRAs, and ControlNet
- Absolute control over generation process
- Active developer and creator community
Could be better
- Requires high-end local GPU
- Steep learning curve for WebUI/ComfyUI
- Out-of-the-box text rendering is weak
