Show HN: Z80-μLM, a 'Conversational AI' That Fits in 40KB#
This project by quesomaster9000 is a character-level language model that runs on a Z80 processor, crammed into just 40KB using 2-bit quantization for extreme efficiency. It's generating massive interest (505 points, 117 comments) as a holiday experiment that proves useful AI doesn't require massive resources—ideal for hobbyists and embedded systems developers exploring low-power, retro-computing applications. Readers should care because it challenges the "bigger is better" narrative, showing how quantization can democratize AI for edge devices.
OpenAI's Cash Burn Will Be One of the Big Bubble Questions of 2026#
An Economist article probes the staggering financial outflow at OpenAI, questioning if the current AI investment frenzy is sustainable or heading for a crash. With 488 points and over 700 comments, the discussion is heated, reflecting HN's skepticism about unchecked hype and economic risks. This matters for anyone in tech or investing, as it highlights the need for viable business models to avoid a dot-com-style reckoning in AI.
Show HN: Use Claude Code to Query 600 GB Indexes over Hacker News, ArXiv, etc.#
Xyra's tool lets you plug Claude Code into a massive public SQL+vector database spanning HN, ArXiv, LessWrong, and more, turning it into a powerful research assistant. The 324 points and lively debate underscore its appeal for knowledge workers tired of manual searches. Developers should take note—it's a blueprint for building semantic search tools that make vast datasets accessible without building infrastructure from scratch.
Animated AI#
This GitHub-hosted site offers visualizations of neural network concepts, making abstract AI ideas like gradients and backpropagation intuitive through animations. It's garnered 295 points and praise for its educational value, with commenters lauding how it bridges theory and practice. For learners and educators, it's a must-see resource that simplifies complex topics, helping to onboard more people into AI without overwhelming math.
2025: The Year in LLMs#
Simon Willison's annual recap dives into the evolution of large language models, covering key releases, breakthroughs, and practical applications from the past year. Scoring 283 points and 151 comments, it's a hot topic for its comprehensive, accessible analysis of trends like fine-tuning and open-source wins. Readers get a distilled view of LLM progress, positioning them to anticipate 2026's innovations in deployment and efficiency.
