lfx-wavespeed

WaveSpeed AI components for Langflow, packaged as a Langflow Extension Bundle.

WaveSpeed AI is a high-performance inference platform for image and video generation models. This bundle exposes it in the Langflow palette — no fork, no PR to Langflow, just pip install.

Install

pip install lfx-wavespeed

Restart Langflow. A WaveSpeed AI bundle appears in the component palette.

Components

All three take a WaveSpeed API Key (get one at https://wavespeed.ai/dashboard) and can be driven by an Agent via tool mode. Each returns a Data payload with url, urls and the raw platform outputs.

The model dropdowns refresh from GET /api/v3/models when you change the key or click the refresh button; without a reachable catalog they fall back to a small curated list.

Why no size / seed inputs

WaveSpeed validates model inputs against each model's declared schema and drops undeclared fields. For the default image models size and seed are not declared, so a UI field for them would look effective while doing nothing. Use Run Model with an explicit JSON payload if a specific model does declare them.

Development

pip install -e ".[test]" langflow
lfx extension validate src/lfx_wavespeed   # static manifest + bundle check
pytest                                     # mocked SDK, no network
ruff check .
lfx extension dev src/lfx_wavespeed        # Langflow with this bundle loaded
