<h1>๐ง FROMAGe</h1> | |
<p>This is the official Gradio demo for the FROMAGe model, a model that can process arbitrarily interleaved image and text inputs, and produce image and text outputs.</p> | |
<strong>Paper:</strong> <a href="https://arxiv.org/abs/2301.13823" target="_blank">Grounding Language Models to Images for Multimodal Generation</a> | |
<br/> | |
<strong>Project Website:</strong> <a href="https://jykoh.com/fromage" target="_blank">FROMAGe Website</a> | |
<br/> | |
<strong>Code and Models:</strong> <a href="https://github.com/kohjingyu/fromage" target="_blank">GitHub</a> | |
<br/> | |
<br/> | |
<strong>Tips:</strong> | |
<ul> | |
<li>Start by inputting either image or text prompts (or both) and chat with FROMAGe to get image-and-text replies.</li> | |
<li>Tweak the level of sensitivity to images and text using the parameters on the right.</li> | |
<li>Check out cool conversations in the examples or community tab for inspiration and share your own!</li> | |
<li>For faster inference without waiting in queue, you may duplicate the space and use your own GPU: <a href="https://huggingface.co/spaces/jykoh/fromage?duplicate=true"><img style="display: inline-block; margin-top: 0em; margin-bottom: 0em" src="https://img.shields.io/badge/-Duplicate%20Space-blue?labelColor=white&style=flat&logo=data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAAAXNSR0IArs4c6QAAAP5JREFUOE+lk7FqAkEURY+ltunEgFXS2sZGIbXfEPdLlnxJyDdYB62sbbUKpLbVNhyYFzbrrA74YJlh9r079973psed0cvUD4A+4HoCjsA85X0Dfn/RBLBgBDxnQPfAEJgBY+A9gALA4tcbamSzS4xq4FOQAJgCDwV2CPKV8tZAJcAjMMkUe1vX+U+SMhfAJEHasQIWmXNN3abzDwHUrgcRGmYcgKe0bxrblHEB4E/pndMazNpSZGcsZdBlYJcEL9Afo75molJyM2FxmPgmgPqlWNLGfwZGG6UiyEvLzHYDmoPkDDiNm9JR9uboiONcBXrpY1qmgs21x1QwyZcpvxt9NS09PlsPAAAAAElFTkSuQmCC&logoWidth=14" alt="Duplicate Space"></a></li> | |
