I've been testing Recraft's flat illustration generation for a few weeks now, specifically to see how it stacks up against using Stable Diffusion with ControlNet for similar tasks. The comparison is interesting from a workflow and control perspective, not just output quality.
For those who haven't tried, here's the core difference in approach:
* **Recraft:** You select the "flat illustration" style and describe your scene. The system handles enforcing the style consistency, line work, and color flatness. It's a high-level instruction. Great for speed.
* **Stable Diffusion + ControlNet:** You start with a base model, then layer on ControlNet modules (like Canny or Scribble) with your own edge map or sketch, and often a LoRA for a specific flat art style. This is a multi-step, granular process.
The trade-off is clear. Recraft gives you a fast, coherent result with almost no setup. With SD, you have immense control but need to build and tune the pipeline yourself. For example, generating a consistent character in different poses is simpler in Recraft. In SD, you'd be wrestling with seed consistency, prompt engineering, and multiple ControlNet weights.
Where SD still wins is when you need to adhere to a *specific existing composition or sketch*. You can feed it a detailed guide image. Recraft's "remix" feature is moving in this direction, but it's not as precise for technical art direction.
For my team's use case—generating spot illustrations for internal tools and documentation—Recraft's simplicity wins for most tasks. We only drop into our SD stack when we have a very specific layout from a designer that needs to be followed pixel-by-pixel. It’s a classic "managed service vs. IaC" decision, but for image generation.
