Flux助手(简易)

If the advanced Flux assistant is the full instrument panel, this is the "one red button." It's the same Alibaba-hosted Flux generation, stripped to the three things a beginner actually needs: which model, what size, and the prompt. That's it. You don't set steps, seed, or guidance - the node hard-codes the sensible defaults per model and hides the knobs entirely.

The model dropdown is the fun part because it does your thinking for you: flux-schnell(快速) for speed, flux-dev(高质量) for quality, flux-merged(优化) for a compromise. Each maps to a step count baked into the node (4, 50, and 30 respectively), which matches what the advanced node auto-configures. size is the same six-entry preset list (1024×1024, 512×1024, 768×512, 768×1024, 1024×576, 576×1024). prompt is a multiline box, api_key is the pack's shared DashScope key. One IMAGE comes out, ready to wire to a preview or save node.

Under the hood it's a single dashscope.ImageSynthesis.call; the returned image URL gets downloaded and converted to a tensor on your GPU, exactly like its advanced sibling. If you've ever wanted to explain "Flux, but without downloading 30 GB" to someone in one sentence, this node is that sentence.

When would you pick this over the advanced version? When you don't care about reproducibility (no seed control means you can't reroll a specific output) and you're happy with defaults. It's the right first Flux node, and it doubles as a quick sanity check - if you want to prove the pack's API key works before building anything complicated, run this with "a red apple on a white table."

Install: ComfyUI Manager → search "ComfyUI-My-Nodes", or cd ComfyUI/custom_nodes && git clone https://github.com/Tagbliton/ComfyUI-My-Nodes and restart. Dependencies come from the pack's requirements.txt (dashscope, openai, requests, soundfile, numpy, urllib3==1.26.20 pinned - leave the pin alone).

Gotchas. The same list index out of range bug that hits flux-schnell in the advanced node lives here too - the README lists it as an open issue for the schnell model, so treat flux-dev(高质量) and flux-merged(优化) as the reliable picks. And the standing caveat for every node in this pack: it's a metered API call, and a DashScope key requires a real-name-verified mainland China account. No key, no image, and it's not your node's fault.
