zhenzhen-recraft-v4.1-fal

Recraft's whole pitch is that it draws like a designer, not like an AI - clean vector-ish graphics, posters, icons, packaging - and it's one of the models people genuinely can't run locally. Comfly_recraft_v4_1_fal is the zhenzhen pack's door to it: a text-to-image node that wraps the Recraft V4.1 endpoint on the fal queue and hands you back a normal ComfyUI IMAGE. The party trick this node adds is color control - you can pin a background and feed it a palette, which is exactly the kind of thing you'd otherwise fight a diffusion model for an hour to get.

Like every *_fal node in this pack, it talks to the fal.ai queue through zhenzhen's proxy at https://ai.t8star.org/fal and uses the token from the zhenzhen shop in its api_key field. Submit, poll, download. FAL routes are prepaid - credits are taken up front and the overcharge refunded after the job lands - and the actual cost scales with output size and how long the queue is.

The inputs that matter

• prompt - required, and it does most of the work. Recraft rewards specific, graphic-design-style language.
• image_size - square_hd (default), square, portrait and landscape 4:3/16:9 presets. Note it's a preset list, not free WxH.
• background_r / background_g / background_b - an RGB background color. Set all three to a real value to use it; any at -1 (the default) disables the background color entirely.
• palette_colors - the interesting one. One RGB triple per line (255,0,0), and the model sticks to that palette. This is the knob that gets you on-brand output.
• enable_safety_checker - on by default; the model's moderation runs server-side, so this is mostly a "let me trip the filter myself" switch.

Outputs are images (tensor), image_urls (strings), and response (the raw API reply, handy when the queue eats your job). poll_interval (6s default) and max_poll_attempts (600 ≈ 1 hour) control the wait; if the queue is slow, raise the attempts rather than assuming it hung.

Installing it

Standard API-pack install - no models to download. ComfyUI Manager, search "Comfyui-zhenzhen", or:

cd ComfyUI/custom_nodes
git clone https://github.com/T8mars/Comfyui-zhenzhen

restart, and paste a zhenzhen shop token (overseas https://ai.t8star.org, or the domestic low-price https://api.seedance.nz) into api_key. The requirements are plain HTTP/image-stack dependencies.

Common issues

• Colors come out wrong anyway - the palette is a strong hint, not a constraint; Recraft will still drift. Re-roll rather than fighting it.
• Background color silently ignored - you left one of the three channels at -1. The node only sends background_color when all three are set.
• Timeouts - the queue backs up at peak; that's what max_poll_attempts is for.

If you need local, controllable graphic design you'd be reaching for a different tool entirely - Recraft's value is that it's already better at "designer output" than anything open-weight. This node just makes it reachable from inside a ComfyUI workflow for a few cents a shot.
