What it does
Use OptimizeGLB to compress and optimize yourglb file to get upto 90% reduction in file size.gltf and texture compression coming soon.
Compress GLB and glTF model files locally in your browser. Adjust texture and geometry settings, compare the result, and download without uploading the model.
Your selected model files are processed on this device, not uploaded for compression. Compression settings with texture quality, mesh optimization, and compatibility controls for balancing file size and visual quality. Smaller model downloads can improve loading time. Measure the optimized model in your target scene and devices. Texture resizing and optional mesh simplification can reduce texture memory and geometry work in the target runtime. Choose conservative settings or enable extensions such as Draco only when your target loader supports them. Compression runs locally in your browser using WebAssembly. Model files you select are not uploaded to OptimizeGLB for processing. There is no…from optimizeglb.com

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hi HN, Today we’re launching GPT-4 answers on Phind.com, a developer-focused search engine that uses generative AI to browse the web and answer technical questions, complete with code examples and detailed explanations. Unlike vanilla GPT-4, Phind feeds in relevant websites and technical documentation, reducing the model’s hallucination and keeping it up-to-date. To use it, simply enable the “Expert” toggle before doing a search. GPT-4 is making a night-and-day difference in terms of answer quality. For a question like “How can I RLHF a LLaMa model”, Phind in Expert mode delivers a…
