Analyzing Semantic Redundancy in LLM Retrieval (Google GIST Protocol)
Last week, Google research published details on GIST (Greedy Independent Set Thresholding), a new protocol presented at NeurIPS 2025. I was fascinated by the paper, so I built a tool to visualize the "No-Go Zones" (redundancy radius) it describes. The Tool: https://websiteaiscore.com/gist-compliance-check The Context (The Paper): To understand the tool, you have to understand the problem Google is solving with GIST: redundancy is expensive.

What it does
In the maker’s words, at launch
Last week, Google research published details on GIST (Greedy Independent Set Thresholding), a new protocol presented at NeurIPS 2025. I was fascinated by the paper, so I built a tool to visualize the "No-Go Zones" (redundancy radius) it describes. The Tool: https://websiteaiscore.com/gist-compliance-check The Context (The Paper): To understand the tool, you have to understand the problem Google is solving with GIST: redundancy is expensive. When generating an AI answer , the model cannot feed 10k search results into the context window—it costs too much compute. If the top 5 results are semantically identical (consensus content), the model wastes tokens processing duplicates. The GIST algorithm solves this via Max-Min Diversity: Utility Score: It selects a high-value source. The Radius: It draws a mathematical conflict radius around that content based on semantic similarity. The Lockout: Any content inside that radius is rejected to save compute, regardless of domain authority. How my implementation works: I wanted to see if we could programmatically detect if a piece of content falls inside this "redundancy radius." The tool uses an LLM to analyze the top ranking URLs for a specific query, calculates the vector embedding, and measures the Semantic Cosine Similarity against your input. If the overlap is too high (simulating the GIST lockout), the tool flags the content as providing zero marginal utility to the model. I’d love feedback on the accuracy of the similarity scoring.

Hey all, Justin here. I previously built Phind, the AI search engine for developers. One of the biggest problems we had there was figuring out what went wrong with bad searches. We had tons of searches per day, but less than 1% of users gave any explicit feedback. So we were either manually digging through searches or making general system improvements and hoping they helped. This problem gets harder with agents. Traces are longer and more complex. It takes more effort to review them, so I'm building a tool that lets you analyze LLM outputs directly to help developers of LLM apps and agents…

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…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
