wtf is openwebui-openrouter-video?

This project is a tool that adds AI video generation to OpenWebUI, a self-hosted chat interface for talking to language models. Once installed, a user's chat assistant can generate short AI videos just by being asked in plain language, without clicking through menus or picking a model manually. The assistant itself decides which video model to use, submits the generation job to OpenRouter, checks on it until it finishes, and then shows the finished video directly inside the chat. The tool pulls its list of available video models live from OpenRouter at the moment it is used, so it automatically supports new models like Sora, Veo, Kling, Seedance, Hailuo, Wan, and Grok as OpenRouter adds them, along with each model's supported resolutions, durations, aspect ratios, and pricing. Once a video finishes generating, the tool downloads the file to the OpenWebUI server itself rather than linking to a temporary URL, which avoids broken links after the original link expires, and embeds it in the chat with a working video player and download link. More advanced options include turning audio on or off where a given model supports it, using a fixed seed for repeatable results, and passing a reference image to guide the video's style. The README is notably careful about how audio behaves differently across models, since some models silently ignore the audio setting and produce sound anyway. Installing the tool means pasting a single Python file into OpenWebUI's tool editor and adding an OpenRouter API key in the tool's settings, a few optional settings control how long the tool waits for a video to finish before giving up. The project depends on the aiohttp Python library, which OpenWebUI installs automatically, and requires an existing OpenWebUI instance to run inside. One notable limitation mentioned in the README is that downloaded videos are never deleted automatically, so a long-running installation that generates many videos will need someone to periodically clear out old files. The project is released under the MIT license.
