Latent Space Guardrails That Reduce Hallucinations by 43 Percent Now Open Source (ycombinator.com)
Heyah,<p>This is Lukasz. I am running Wisent, a representation engineering company. I created guardrails that allow you to block certain patterns of LLM activations on the latent space level. It is now fully self-hosted and open source. Think stopping hallucination, harmful thoughts of the LLM or bad code generation. Let me know how it works for your use case- happy to help you generate the most value from it.<p>Check out more at https://www.wisent.ai/ or https://www.lukaszbartoszcze.com/

Yann LeCun, Pioneer of AI, Thinks Today's LLM's Are Nearly Obsolete (newsweek.com)
Ask Yann LeCun—Meta's chief AI scientist, Turing Award winner, NYU data scientist and one of the pioneers of artificial intelligence—about the future of large language models (LLMs) like OpenAI's ChatGPT, Google's Gemini, Meta's Llama and Anthropic's Claude, and his answer might startle you: He believes LLMs will be largely obsolete within five years.

Multi-Token Attention (arxiv.org)
Soft attention is a critical mechanism powering LLMs to locate relevant parts within a given context. However, individual attention weights are determined by the similarity of only a single query and key token vector. This "single token attention" bottlenecks the amount of information used in distinguishing a relevant part from the rest of the context.

AI Ambivalence (nolanlawson.com)
I’ve avoided writing this post for a long time, partly because I try to avoid controversial topics these days, and partly because I was waiting to make my mind up about the current, all-consuming, conversation-dominating topic of generative AI.

Show HN: Open Responses – Self-hosted OpenAI Responses API, works with any model (github.com/julep-ai)
Open Responses lets you run a fully self-hosted version of OpenAI's Responses API. It works seamlessly with any large language model (LLM) provider—whether it's Claude, Qwen, Deepseek R1, Ollama, or others. It's a fully-compatible drop-in replacement for the official API. Swap out OpenAI without changing your existing Agents SDK code.

Wikipedia is struggling with voracious AI bot crawlers (engadget.com)
Wikimedia has seen a 50 percent increase in bandwidth used for downloading multimedia content since January 2024, the foundation said in an update. But it's not because human readers have suddenly developed a voracious appetite for consuming Wikipedia articles and for watching videos or downloading files from Wikimedia Commons. No, the spike in usage came from AI crawlers, or automated programs scraping Wikimedia's openly licensed images, videos, articles and other files to train generative artificial intelligence models.

LLM Workflows then Agents: Getting Started with Apache Airflow (github.com/astronomer)
This repository contains an SDK for working with LLMs from Apache Airflow, based on Pydantic AI. It allows users to call LLMs and orchestrate agent calls directly within their Airflow pipelines using decorator-based tasks. The SDK leverages the familiar Airflow @task syntax with extensions like @task.llm, @task.llm_branch, and @task.agent.

Gemini 2.5 Pro vs. Claude 3.7 Sonnet: Coding Comparison (composio.dev)
Google just launched Gemini 2.5 Pro on March 26th, claiming to be the best in coding, reasoning and overall everything. But I mostly care about how the model compares against the best available coding model, Claude 3.7 Sonnet (thinking), released at the end of February, which I have been using, and it has been a great experience

Karpathy's 'Vibe Coding' Movement Considered Harmful (nmn.gl)
Last Tuesday at 1 AM, I was debugging a critical production issue in my AI dev tool. As I dug through layers of functions, I suddenly realized — unlike the new generation of developers, I was grateful that I could actually understand my codebase. That’s when I started thinking more about Karpathy’s recent statements on vibe coding.
