Show HN: Costile – open-source proxy, blocks AI API requests when budget is hit
I got a surprise bill. Nothing catastrophic, but enough to make me dig into why — an agent had hit a retry loop and kept calling the API for hours. There's no way to set a hard cap on the Anthropic or OpenAI APIs. You can get an email after the fact, but nothing that actually stops requests mid-flight.So I built a proxy. You swap one environment variable, it routes through Costile instead of calling Anthropic directly, and when you hit your daily or monthly limit it blocks further requests
Show HN: A book that builds GPT-2, Llama 3, DeepSeek from scratch in PyTorch
I'm a software engineer who works with LLMs professionally (Forward Deployed Engineer at TrueFoundry). Over the past year I built up implementations of five LLM architectures from scratch and wrote a book around them.The progression:- Ch1: Vanilla encoder-decoder transformer (English to Hindi translation) - Ch2: GPT-2 124M from scratch, loads real OpenAI pretrained weights - Ch3: Llama 3.2-3B by swapping 4 components of GPT-2 (LayerNorm to RMSNorm, learned PE to RoPE, GELU to SwiGLU, MHA to
Show HN: I built a contextual explainer to replace my dictionary extensions
I found that I often shy away from posts on Hacker News or sites like ScienceMagazine because I don’t understand every second word on the page.A simple dictionary extension doesn’t really help in these situations, because I’m not looking for the literal meaning of a word.Like one time I was reading a post about Rust compilers and the dictionary extension just failed hilariously.. “Rust” (the programming language, you fool!! not the thing that forms on iron when it oxidises -__-).What I actually
A brief generational overview of the tech industry
Modern consumer-focused technology, the finished products that we use in our day-to-day lives, is defined by the tech industry(AKA Big Tech, tech companies, the Internet, whatever you want to call it). Broadly speaking, this is the industry that has been the main driver of innovation in the past 50 years: producing wealth, increasing the standard of living, and improving human productivity. As of 2026, I can see this industry as having 2 clear generations of societal impact. I will list various
Show HN: Mimikos – Zero-config mock server that infers API behavior from OpenAPI
I built a mock server that reads an OpenAPI spec and serves realistic, deterministic responses — no mock definitions, no config files.``` mimikos start petstore.yaml ```That's the entire setup. Mimikos parses your spec, classifies each endpoint (create, fetch, list, update, delete), and generates schema-valid responses with realistic data. Same request always returns the same response, so it's safe for snapshot tests and CI.What's different from Prism, WireMock, etc.:Most mock ser
