NAIA Request Random Prompt (with Seed)

Here's the thing nobody tells you about the main random-prompt node: it re-rolls every single run, and it's always dirty, so it drags the cache down with it. If you lock your seed trying to reproduce an image you liked, you get a new prompt anyway, and the image is gone. This node, NAIA Request Random Prompt (with Seed), fixes exactly that by making the NAIA request behave like every other seed-driven value in ComfyUI: same seed → same prompt, new seed → new roll.

It's the stripped-down sibling. Where the main node gives you the full Prompt Engineering override surface, this one drops all of that - use_naia_settings is locked to true, so it always uses NAIA's desktop settings as-is. What you get instead is a seed input and the four override toggles. If all you want is "roll me a fresh Danbooru prompt per run, tied to my seed," this is the cleanest node in the pack.

How it works

The mechanism is the interesting part. Instead of the always-rerun float("NaN") trick, this node's IS_CHANGED returns a hash of every relevant input - seed, prompt, negative, width, height, their override toggles, host, port. ComfyUI compares that hash between runs, so:

• Seed unchanged, nothing else touched → hash matches → the node doesn't re-execute, NAIA isn't called, and the previous run's prompt, negative, and resolution are reused. Full native caching, no wasted request.
• Seed changed (or Randomize rolls it) → hash differs → it fires one POST /api/comfyui/random and pulls a brand-new prompt.

So the seed isn't just parked on the node as decoration - it is the re-roll trigger. Lock the seed and you can keep iterating on sampler settings against the same prompt; randomize it and every queue is a surprise.

Inputs and outputs

The seed input is a plain INT (0 to 2⁶⁴−1), the same range as the KSampler's. prompt / negative_prompt / width / height are your fallback values, used when the matching override_* toggle is off. Each toggle defaults to true, meaning NAIA's fetched value wins - flip override_width off, for instance, and you keep a fixed 1024×1024 while the prompt still rolls.

Outputs are the standard four: prompt, negative_prompt (strings), width, height (ints). prompt → positive CLIP Text Encode via Convert Widget to Input; width/height → EmptyLatentImage. The usual negative advice applies - NAIA's negative is static, so you'll typically leave override_negative off and type your own.

Install

Same pack, same story - no models, two tiny deps:

cd ComfyUI/custom_nodes
git clone https://github.com/DNT-LAB/comfyui-naia-bridge.git
cd comfyui-naia-bridge
pip install -r requirements.txt

Or search comfyui-naia-bridge / naia in ComfyUI Manager. Needs NAIA 2.0 with the sync-API patch, Web Session on, and a search run first.

One honest caveat

Because this node uses NAIA's desktop settings and doesn't expose the preprocessing/pre-post widgets, you're trading the main node's per-request control for seed sanity. If you need use_naia_settings=false style overrides, you want NAIA Request Random Prompt instead. But for the most common use - "roll me prompts, let me reproduce them" - this is the one I'd reach for. It's the only node in the bridge that plays nicely with ComfyUI's cache instead of fighting it.
