Ideogram 4.0 Remix

Ideogram 4.0 is the release the community argued about for weeks - open weights in June 2026, but non-commercial, quantized-only, and with a safety filter trained into the model that made ComfyUI's lead developer publicly disclaim it wasn't a bug. This node is none of that. Runware_ideogram_4_0_remix is the hosted API version of the 4.0 remix, served through Runware. No weights, no license treadmill, no refusal-image-bytecode forensic debates. You get the 4.0 engine, you pay per call.

It's the remix variant of the current-generation model: give it a seed image and a prompt, and it transforms the original with 4.0's strength - which, notably for this family, includes its character and IP recall. People found that recall was the real standout of 4.0, and it applies here too.

How it works

Required: seedImage and positivePrompt. Width/height are optional this time (defaulting to 1024) rather than required - one less thing to trip over.

The inputs that actually matter:

• strength (boolean) + strength_value (0 to 1, step 0.01) - this is the pair to understand. strength defaults to false, which means "let the model pick." Flip it on and strength_value overrides the automatic choice. Lower values keep more of the original; higher values drift further. That "off = model default" gating pattern is used all over this pack, so once you've seen it here you've seen it everywhere.
• settings.renderingSpeed - TURBO / DEFAULT / QUALITY. The classic speed-quality tradeoff. DEFAULT is a fine starting point.
• settings.copyrightDetection - a 4.0-specific opt-in: post-generation checks using Hive's likeness and logo detectors. Worth flipping on for commercial-ish work, knowing the rest of the pipeline may still trip the moderation anyway.

There's no negativePrompt on this node - 4.0 dropped it, so don't go hunting. numberResults gives you up to 20 variations, each on its own seed.

Output is a native IMAGE, straight into Preview Image or Save Image.

Installing it

Same pack, same drill as the rest of the Runware nodes:

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

Restart, set your API key in ComfyUI Settings → Runware API key (or the RUNWARE_API_KEY env var). Light dependencies - runware-sdk, pillow, soundfile - and zero model downloads, which is the whole pitch.

Where people get burned

Two things. First, people confuse this with the open-weights 4.0 and expect to fiddle with the JSON prompt builder or fight the filter - you don't, because you're renting the hosted engine and its moderation runs server-side (safety.checkContent will surface as NSFW: yes/no in the title bar). Second, the strength/strength_value split confuses everyone once: leaving strength off isn't a bug, it's "auto," and the moment you flip it on your slider actually does something. And as always with this pack: no key means instant errors, and it's a paid top-up API - cheap per image, but mind the minimum top-up before you batch 20 results.
