ByteDance Seedream V5.0 lite (Official Edition)

Seedream V5.0 lite, text-to-image, running in the cloud through BizyAirPlus's official API route. Prompt and size in, high-resolution image out, zero local compute - the same two-field simplicity as the earlier Seedream nodes, with the newest model underneath.

Seedream has been ByteDance's flagship image line for the whole run, and V5.0 lite is the generation that became the sensible default: it's the current front of the line at the cheaper tier, before you step up to V5.0 Pro. For most everyday generation - concept art, product mockups, characters, editorial-style images - lite is the one you'll actually reach for. The Pro tier is for when the output needs to survive scrutiny; lite is for everything that needs to be good and get done.

How it works

Output node in the BizyAirPlus cloud layer. Flip BizyAirPlus ON in the action bar, and the node forwards your prompt and size to Seedream's service via the vendor's direct API, then pulls the finished image back into your workflow. The model is closed - there are no weights to download, and your GPU never gets involved.

The inputs that matter

• prompt - multiline, free-form. This is where the quality lives; Seedream is responsive to descriptive language.
• size - output dimensions as a string, default 2048x2048.

The optional pair is the standard one across the pack: api_config (per-request base URL/API key override) and skip_error (placeholder output instead of aborting the workflow on failure).

The outputs

image - an IMAGE tensor for saving, upscaling or feeding elsewhere. urls - the direct result link. request_id - the trace ID for support.

Installing it

Ships in BizyAirPlus. ComfyUI Manager → search "BizyAirPlus", or:

cd ComfyUI/custom_nodes
git clone https://github.com/siliconflow/BizyAirPlus.git
cd BizyAirPlus
python -m pip install -r requirements.txt

Restart, turn BizyAirPlus ON, and enter the key from bizyair.ai when prompted (stored at ~/.BizyAirPlus/apikey.ini, or set BIZYAIR_API_KEY). The node logic lives in the bizytrd / bizyair-cloudberry pip packages; the install is light and there's nothing to download past it.

Gotchas

First-run errors are almost always the button OFF or a missing key - the ComfyUI console has the real message. The "is BizyAir malware?" threads you may have seen were an old Manager auto-install mixup, since fixed; this is a legitimate SiliconFlow service. On the node: size is a plain string, so 2048x2048 parses and creative spacing doesn't. And since every call bills your account, it's worth knowing the official T2I node has no seed or aspect-ratio knobs - you vary results by editing the prompt, or move up to the 5.0 Pro nodes if you need more control.
