Rubbrband – Evaluating generated images at scale
Hey HN! We’re the founders of Rubbrband (https://www.rubbrband.com/), a evaluation platform for image generation models like Stable Diffusion. We provide a monitoring application to detect deformed human features in AI generated images at scale. For example, we automatically flag images of people with deformed eyes or hands. We’ve worked with several companies leveraging generative image models in production, and found that one of the main problems is that it’s hard to filter images for good quality sample at scale. Typically, teams will have to manually look through the…
In plain words
Rubbrband is an evaluation platform that monitors AI-generated images from models like Stable Diffusion to automatically detect deformed human features such as malformed eyes or hands. It addresses the challenge companies face when producing large volumes of generated images by eliminating manual quality review. The platform alerts users when images contain defects, helping teams maintain quality standards at scale without labor-intensive manual screening.

Hey HN! We’re the founders of Rubbrband (https://www.rubbrband.com/), a evaluation platform for image generation models like Stable Diffusion. We provide a monitoring application to detect deformed human features in AI generated images at scale. For example, we automatically flag images of people with deformed eyes or hands. We’ve worked with several companies leveraging generative image models in production, and found that one of the main problems is that it’s hard to filter images for good quality sample at scale. Typically, teams will have to manually look through the images for these samples, which is slow and expensive. We wanted to build a monitoring solution that lets you to see all of the images you’ve generated, and to automatically be alerted when an image was generated with a deformity. We’ve started by building evaluators that detects deformities in human features, like face and hands. We’re focused on expanding rapidly into build evaluators for other types of images, like gaming and design assets. We charge using a storage-based pricing model. Rubbrband costs 5¢ per image to use, with your first 1000 images uploaded free. We’d love to hear your thoughts and critiques, if you have any feature requests please let us know!

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

I saw this [0] pretty cool thread by user revskill, and wanted a quicker way to search through it, but also to keep them all in one place so I can read them at my leisure whenever I get time. Right now is like 60 lines of Ruby using Nokogiri, but I will certainly look into it further down the line and improve the list. There's a cronjob checking the thread every 12 hours but I will eventually shut that down and it will become static after that. There are some really awesome blogs in there. I really recommend going through the list, it made my day. [0] "Could you share your personal blog…
