Janus Pro 1B running 100% locally in-browser on WebGPU

The image generation results are extremely poor, but it's exciting that it does _anything_ in the browser.

The reason why this doesn&#x27;t work on Firefox:<p><a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=41157383">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=41157383</a>

Hi HN! We’re excited to launch JanusPro-AI, an open-source multimodal model from DeepSeek that unifies text-to-image generation, image understanding, and cross-modal reasoning in a single architecture. Unlike proprietary models, JanusPro is MIT-licensed and optimized for cost-efficiency—our 7B-parameter variant was trained for ~$120k, outperforming DALL-E 3 and Stable Diffusion XL in benchmarks like GenEval (0.80 vs. 0.67) 25.<p>Why JanusPro? Decoupled Visual Encoding: Separates image generation&#x2F;understanding pathways, eliminating role conflicts in visual processing while maintaining a unified backbone 2.<p>Hardware Agnostic: Runs efficiently on consumer GPUs (even AMD cards), with users reporting 30% faster inference vs. NVIDIA equivalents 2.<p>Ethical Safeguards: Open-source license restricts military&#x2F;illegal use, aligning with responsible AI development<p>please checkout the website: <a href="https:&#x2F;&#x2F;januspro-ai.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;januspro-ai.com&#x2F;</a>

Happy to have these models running locally on a browser. However, the results are still quite poor for me. For example: <a href="https:&#x2F;&#x2F;imgur.com&#x2F;a&#x2F;Dn3lxsU" rel="nofollow">https:&#x2F;&#x2F;imgur.com&#x2F;a&#x2F;Dn3lxsU</a>

well it was a long shot anyway but it doesn’t seem to work on mobile. (tried on iOS safari on iPhone 11 pro)<p>a 1B model should be able to run in the RAM constraints of a phone(?) if this is supported soon this would actually be wild. Local LLMs in the palm of your hands

I like the local running of this and learning about how it works.<p>Q:These models running in WebGPU all seem to need nodejs installed. I that for just the local &#x27;server side&#x27;, can you not just use a python http server or tomcat for this and wget files?
