Ideogram 3.0

Ideogram 3.0 is the serious one. The 2a and 2a Remix nodes are for quick text-and-image jobs; this is the tier where Ideogram added real photo realism, style references, and - the headline feature - character consistency. That's the thing local checkpoints still fight with daily (the KB's identity-preservation topic exists precisely because nobody does it effortlessly), and here it's a couple of image sockets away.

It's a cloud node through the Runware/ComfyUI-Runware pack, so again: no local model, no GPU, native IMAGE out. But it's the most parameter-heavy Ideogram node in the pack, so it deserves a walkthrough.

How it works

The node calls Ideogram 3.0 through Runware's SDK. What makes it different from the 2.x nodes:

• Character reference. providerSettings.ideogram.characterReferenceImages - feed it 1-3 images of a person or character, and the output keeps that identity. The optional characterReferenceImagesMask lets you tell it which pixels are the character, which tightens consistency a lot.
• Style reference. providerSettings.ideogram.styleReferenceImages - transfer visual language from reference images.
• Style presets. providerSettings.ideogram.stylePreset has 63 curated presets - ART_DECO, BAUHAUS, BLUEPRINT, 80S_ILLUSTRATION, AURA, and friends. This is where you stop describing an aesthetic in 40 words and just pick the drop-down.
• Upscale. upscaleFactor of 1, 2, or 4 doubles/quadruples dimensions in the same call instead of sending you off to a separate upscale pass.

The inputs that matter

• positivePrompt - required. The scene.
• width / height - required, 1024 default.
• providerSettings.ideogram.characterReferenceImages (+ optional ...Mask) - the consistency feature. The reason to pick this node over every other Ideogram node in the pack.
• providerSettings.ideogram.stylePreset - the 63-preset dropdown. (default) if you want to stay uninfluenced.
• providerSettings.ideogram.styleType - AUTO / GENERAL / REALISTIC / DESIGN / RENDER_3D / ANIME / FICTION.
• upscaleFactor - do it here, don't buy a second pass.
• negativePrompt, seed, providerSettings.ideogram.magicPrompt, renderingSpeed - familiar by now.

Installing

cd ComfyUI/custom_nodes
git clone https://github.com/Runware/ComfyUI-Runware
pip install -r ComfyUI-Runware/requirements.txt

Restart, or ComfyUI Manager → search Runware. API key via Settings, RUNWARE_API_KEY, or runware auth login.

Where people get burned

Character consistency is real but not magic - it's strongest when the reference images are the same character in consistent lighting, and the mask helps when they aren't. Don't skip the mask and then complain the face drifts on a complex group shot. Also, one thing to keep in mind from the KB: Ideogram 4.0 shipped open weights in June 2026 and then promptly lost the ecosystem race to Krea 2 over licensing, which tells you Ideogram's open future is uncertain - but these API nodes don't depend on that, they keep working. And since 3.0 is the priciest Ideogram tier here, the title-bar cost readout is worth actually glancing at.
