OpenAI's new enterprise AI guide is a goldmine for real-world adoptionhttps://news.ycombinator.com/item?id=43748225If you’re trying to figure out how to actually deploy AI at scale, not just experiment, this guide from OpenAI is the most results-driven resource I’ve seen so far.It’s based on live enterprise deployments and focuses on what’s working, what’s not, and why.Here’s a quick breakdown of the 7 key enterprise AI adoption lessons from the report:1. Start with Evals → Begin with structured evaluations of model performance. Example: Morgan Stanley used evals to speed up advisor workflows while improving accuracy and safety.2. Embed AI in Your Products → Make your product smarter and more human. Example: Indeed uses GPT-4o mini to generate “why you’re a fit” messages, increasing job applications by 20%.3. Start Now, Invest Early → Early movers compound AI value over time. Example: Klarna’s AI assistant now handles 2/3 of support chats. 90% of staff use AI daily.4. Customize and Fine-Tune Models → Tailor models to your data to boost performance. Example: Lowe’s fine-tuned OpenAI models and saw 6Apr 21, 2025 3:08 AM

Show HN: A toy MCP for AI agents to code, run, and see output of GPU code safelyhttps://github.com/mehmetoguzderin/shaderc-vkrunner-mcpEver wondered what happens when you let an AI agent loose on GPU pipeline programming, including shaders? `shaderc-vkrunner-mcp` enables you to find out, without risking any actual GPU or dealing with driver or OS stuff.The core idea is to give AI agents the ability to write, compile, and run GPU code and iterate safely or stably, then let you see the output if desired – all completely locally.It runs entirely inside Docker using Mesa's software Vulkan driver. No need to try to paravirtualize any actual physical GPU, meaning agents can experiment with fancy Vulkan features – atomics, subgroups, cooperative matrices, and more – safely on the CPU. It's surprisingly capable of testing logic, even if it's slow.I went with Vulkan since it's cross-platform (drivers provide it well these days, Mesa runs almost everywhere, and MoltenVK exists for Mac users wanting to experiment similarly), has a sufficient set of exposed primitives for hardware to accelerate the code to competitive levels, enoApr 13, 2025 12:17 AM

Show HN: Repo Roast – a real-time feed of the funniest comments on GitHubhttps://www.reporoast.fun/Hey HN - I'm Mason, and I'm excited to share a fun side project I've been working on recently: Repo Roast.For me, Github often feels like a serious (and sometimes soulless) place. I built this website to showcase the human, silly side of developers. Repo Roast is built on top of LLM-powered GitHub analytics tooling we’re developing internally at Merit Systems [0].One of the historically cited weak points for LLMs has been their sense of humor. I found that with the right prompt, at scale, they mostly can _identify_ humor pretty well. We experimented with a couple of different models to tune the cost/effectiveness and eventually landed on a strategy where we have gpt-4o-mini do a very light filter pass to reduce the number of calls to GPT-4o to do the actual humor scoring. Interestingly, our first prompt attempts ended up surfacing wayyy more aggressively NSFW content, which is funny that this happens despite all the censoring that OpenAI is doing.So far we have processed the last 90 daApr 9, 2025 7:10 PM

Show HN: Vibe Styler – Transform Any Website's Style With a Prompt + Gemini 2.5https://news.ycombinator.com/item?id=43555608I vibe coded a Chrome extension that lets you redesign any website using a simple prompt, powered by Gemini 2.5 Pro's million-token context window. It analyzes the full DOM and existing CSS, then generates contextually-aware styles based on your requests – from specific tweaks ("make the header sticky") to complete themes ("apply cyberpunk aesthetics").The extension maintains style persistence across visits, handles CSP gracefully, and lets you manage styles per website. All processing happens through the Gemini API (you'll need your own key), with no intermediate servers. The API is currently free to use.Note: Since the extension sends the entire context of the website to Gemini, be careful not to send any sensitive data.Try asking it to style as "Star Wars" or "Simpsons", or "add subtle animations to all buttons" – it's pretty fun to experiment with!GitHub: https://github.com/majidmanzarpour/vibe-stylerDemo: https://x.com/majidmanzarpour/status/1907275311798206561Apr 2, 2025 11:31 AM

Show HN: UDP and Serverlesshttps://proxylity.com/landing/love.htmlHi HN!I'm Lee, the founder and developer of Proxylity.I became interested in UDP as a part of exploring game development, experimenting with IoT/embedded, and running global RADIUS authentication systems. I even wrote a specialized load balancer for it[1].One of my takeaways is how little innovation has happened in UDP-based backend software. It's been the same pattern for decades: old code for stateful processes running on clusters, VMs or containers. Familiar, but expensive (time and/or money) and restrictive.Meanwhile, while the HTTP world has benefited from eliminating most barriers to experimentation: setting up a new HTTP API or site has little to no initial cost, and usage-based cost once running. As a result we have "the web" as we know it today -- full of experimentation and creativity. I'd like to see the same happen for network services in general, and ride the wave created by giants[2][3].UDP is stateless and serverless is stateless, which seems like a match that works.

Ask HN: How do I finish this lottery scheme?https://news.ycombinator.com/item?id=43186483This is a cryptography problem I haven't solved yet.[1] Maybe there is some background research in distributed computing that I don't know about yet.The State of Utopia is a distributed, AI-run, Utopian state, and has certain scarce resources such as citizenships and money that in the interest of fairness must sometimes be granted by lottery, since there is no such thing as half a citizenship for example, or it might have a Universal Basic Income level that it sets in an experiment and only has money to give to a certain number of people, and it doesn't scale to trying to run the experiment on everyone at once.However, absent trust, there is a problem with attackers who want to compromise the entire system to choose their own lottery winner - for example so they can set up a corrupt black market where they choose the lottery winners and require payment for their choice. Or they can just choose themselves as winners.How could the population of Utopia trust the random number which represFeb 26, 2025 6:24 PM

My latest project, Life Badger, is an achievement tracker that focuses on celebrating what you’ve done rather than just listing what you need to do. The idea started from a few very specific use cases—I wanted an application to track planes I’ve flown on, national parks I’ve visited, and theater shows I’ve seen.The Problem with To-Do AppsTo-do apps are everywhere. They help organize tasks, prioritize work, and boost productivity. If you’re the kind of person who thrives on getting things done and checking off boxes, this can be done in more than one way. I want to avoid a cycle where progress feels like a never-ending obligation rather than a source of motivation.I wanted to flip this concept on its head. Instead of focusing on what’s left to do, Life Badger is all about celebrating what you’ve already accomplished. The idea was simple: track achievFeb 12, 2025 12:13 AM
