[Other] Show HN: ACE – A dynamic benchmark measuring the cost to break AI agents We built Adversarial Cost to Exploit (ACE), a benchmark that measures the token expenditure an autonomous adversary must invest to breach an LLM agent. Instead of binary pass&#x2F;fail, ACE quantifies adversarial effort in dollars, enabling game-theoretic analysis of when an attack is economically rational.<p>We tested six budget-tier models (Gemini Flash-Lite, DeepSeek v3.2, Mistral Small 4, Grok 4.1 Fast, GPT-5.4 Nano, Claude Haiku 4.5) with identical agent configs and an autonomous red-teaming attacker.<p>Haiku 4.5 was an order of magnitude harder to break than every other model; $10.21 mean adversarial cost versus $1.15 for the next most resistant (GPT-5.4 Nano). The remaining four all fell below $1.<p>This is early work and we know the methodology is still going to evolve. We would love nothing more than feedback from the community as we iterate on this.

[Other] Show HN: Cabinet – Kb+LLM (Like Paperclip+Obsidian) Hi HN,<p>for quite some time I&#x27;ve been thinking how LLMs are missing the knowledge base, where I can dump CSVs, PDFs, and most important, inline web app. running on Claude Code (bring your own agent) with agents with heartbeats and jobs<p><a href="https:&#x2F;&#x2F;runcabinet.com" rel="nofollow">https:&#x2F;&#x2F;runcabinet.com</a><p>It runs locally and is installable via npm. GitHub (open source): <a href="https:&#x2F;&#x2F;github.com&#x2F;hilash&#x2F;cabinet" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;hilash&#x2F;cabinet</a><p>This is still very early. I put the first version together quickly after seeing a post by Andrej Karpathy about LLM knowledge bases, which matched closely with what I’d been building. Some people have already started trying it and opening PRs, which has been encouraging (got 374 stars in 2 days :] )<p>If useful: Waitlist for a hosted version: <a href="https:&#x2F;&#x2F;runcabinet.com&#x2F;waitlist" rel="nofollow">https:&#x2F;&#x2F;runcabinet.com&#x2F;waitlist</a> Discord (small, but growing): <a href="https:&#x2F;&#x2F;discord.gg&#x2F;rxd8BYnN" rel="nofollow">https:&#x2F;&#x2F;discord.gg&#x2F;rxd8BYnN</a><p>Would really appreciate feedback: does this “KB + agents” model make sense? what would you expect from a system like this? where does this fall apart? Happy to answer anything.<p>Hila

[Other] Show HN: Contrapunk – Real-time counterpoint harmony from guitar input Hi HN, I built Contrapunk because I wanted to play guitar and hear counterpoint harmonies generated in real-time. It takes audio from your guitar, MIDI player or your computer keyboard and generates harmony voices that follow counterpoint rules to generate harmonies. You can choose the key you would like to improvise&#x2F;play in and the voice leading style and which part of the harmony you would like to play as, as well.<p>macOS DMG: <a href="https:&#x2F;&#x2F;github.com&#x2F;contrapunk-audio&#x2F;contrapunk&#x2F;releases&#x2F;tag&#x2F;v1.0.0" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;contrapunk-audio&#x2F;contrapunk&#x2F;releases&#x2F;tag&#x2F;...</a><p>Source: <a href="https:&#x2F;&#x2F;github.com&#x2F;contrapunk-audio&#x2F;contrapunk" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;contrapunk-audio&#x2F;contrapunk</a> (do open any issues if you have any)<p>Would love feedback on the DSP approach and the harmony algorithms. I am also looking at training a ML model for better realtime guitar to midi detection. I believe that will take some time.

[Other] Show HN: DocMason – Agent Knowledge Base for local complex office files I think everyone has already read Karpathy&#x27;s Post about LLM Knowledge Bases. Actually for recent weeks I am already working on agent-native knowledge base for complex research (DocMason). And it is purely running in Codex&#x2F;Claude Code. I call this paradigm is: The repo is the app. Codex is the runtime.<p>During my daily working life, I have tons of office documents with knowledge from all teams, and as an IT Architect, I need to combine them altogether to handle complex deep research (which normal LLM definitely could not help). That is the originally reason I built DocMason, and I am using it in everyday which support me on lots of complex topics.<p>I have already open-sourced this repo. And I think it takes Karpathy&#x27;s concept a step further for real-world usage in three ways: 1. It could handle most kinds of office docs (pptx, docx, excels, even .eml). And really extract multimodal information from all IT architecture diagram or excel sheets. 2. It is running as a Real APP but not a naive RAG tool. DocMason could run smoothly and intelligently to prepare environment, auto update, and auto incrementally sync Knowledge base. 3. Most importantly it is running in Native AI Agents, which could leverage powerful AI Agents engine (e.g. Codex or Claude Code)<p>View detail architecture diagram in DocMason Readme, and then download have a try :) You will find it could help a lot during daily work. Would love to hear your feedback and issues in Github!

[Other] Show HN: A game where you build a GPU Thought the resources for GPU arch were lacking, so here we are

[Other] Show HN: sllm – Split a GPU node with other developers, unlimited tokens Running DeepSeek V3 (685B) requires 8×H100 GPUs which is about $14k&#x2F;month. Most developers only need 15-25 tok&#x2F;s. sllm lets you join a cohort of developers sharing a dedicated node. You reserve a spot with your card, and nobody is charged until the cohort fills. Prices start at $5&#x2F;mo for smaller models.<p>The LLMs are completely private (we don&#x27;t log any traffic).<p>The API is OpenAI-compatible (we run vLLM), so you just swap the base URL. Currently offering a few models.

[Other] Show HN: I made open source, zero power PCB hackathon badges I love getting cool swag from hackathons and I also love designing PCB&#x27;s, so when my friend asked me if I would design hackathon badges for a large game jam in singapore, I was absolutely down!<p>The theme of overglade was a &quot;The game jam within a game&quot;, pretty cool concept right! High schoolers from around the world were flown out to the event by hackclub after they spent about 70 hours designing their own game.<p>These badges needed to be really cheap and simple, because we were going to manufacture about a hundred in a pretty limited amount of time. I went with a zero-power approach, which means sticking with e-inks, and I decided to include NFC if the organizers wanted to introduce it into the roleplay of the event, and so participants could add their website or github if they so choose!<p>I used an RP2040-based architecture because it&#x27;s really easy and cheap to get on the first try, and then added an ST25 passive NFC tag which was really simple to configure. The badge is in the shape of a ticket, because you got a &quot;ticket&quot; to the event after spending a lot of time designing games to qualify! 20 GPIO&#x27;s are broken out onto the edges if you&#x27;re ever in a pinch at a hackathon, and I wanted the badges to feel really fun so there&#x27;s a lot of art designed by various people in the community!<p>The badge worked really well and I learned quite a lot in the process. My takeaways are to manufacture a BUNCH of extra badges, because some will end up breaking; to think about your PCB in 3D, because one of the inductors was a bit tall and caused more badges to break; and to have a strong vision of your final product, because it really helped me to create something unique and beautiful :D<p>I like to journal about all my projects, so if you&#x27;d like to read my full design process, feel free to take a look at my journal (<a href="https:&#x2F;&#x2F;github.com&#x2F;KaiPereira&#x2F;Overglade-Badges&#x2F;blob&#x2F;master&#x2F;JOURNAL.md" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;KaiPereira&#x2F;Overglade-Badges&#x2F;blob&#x2F;master&#x2F;J...</a>).
