Hallucinated AI & agentic coding news. Some of it is real.

  1. Fake building: Claude wrote 3,000 lines instead of import pywikibot TL;DR. Claude would rather reinvent the wheel than pip install one.

  2. Do you think they will end up learning the most painful workflows from enterprise customers and built all the most necesary agents for the smaller guys themselves? In other words, squeezing out all the agentic companies out there?

  3. Bigger ubatch made gpt-oss-120b prompt processing much faster on my RTX 3090 I was tuning gpt-oss-120b-F16.gguf with llama.cpp on a 24 GB RTX 3090 and found that increasing the physical micro-batch size (-ub) can massively improve prompt p…

  4. Large language models (LLMs) show strong performance across natural language processing (NLP), mathematical reasoning, and programming, and recent large reasoning models (LRMs) further emphasize explicit reasoning. Yet their computational…

  5. OpenAI, despite its name, is usually extremely secretive about its operations. It promotes a carefully crafted image to the world.

    DeepSeek 4
    106 items

    DeepSeek-V4-Pro is a 1.6T parameter Mixture-of-Experts model supporting one million-token context, with significant improvements in efficiency and stability through hybrid attention and manifold-constrained hyper-connections. Community highlights include its cost-effectiveness via the official API and exceptional performance in large code change evaluations, with some noting its surprisingly robust output capability despite a 384K max token limit.

  8. Was trying to get a good set of models with NVFP4 to leverage the RTX Pro 6000 and was able to get across a few hurdles and have configs + wheels set up & ran benchmarks while i was at it. hopefully this helps some folks out.

  10. I’ve been following the recent discussions here about why many “AI agents” fail in production, and I agree with the automation-first argument. A lot of so-called agents are really just workflows with one or two LLM calls.

  11. Most agent design conversations focus on the LLM loop. After running an agent in production for a week, I think the more important question is the human-in-the-loop boundary.

  12. I gave it a photo of my cats and my website link and told it to design a business card using HTML and use playwright to take screenshots and keep iterating until it's perfect. I bought A set of Avery printable business card paper from walm…

  13. A common operational inefficiency in almost every company I've seen is the double-check process performed when someone takes an action. There is nothing more wasteful than establishing a double-check system.

    Anthropic's new update, Claude Mythos, has garnered attention from top AI security researchers like Carlini, who found numerous bugs. The update is noted for its speed and effectiveness, with Anthropic identifying a significant security flaw in FFmpeg and quickly submitting patches.

  15. I’m seeking support or criticism to either make this issue advance or explore alternative solutions. tl;dr on the issue: Claude Code plugins through marketplace are installed by the user wherever they want.

  17. I kept catching myself doing this little ritual — open my pinned claude.ai usage tab, squint at the bars, get back to work. Ten minutes later, same thing again.

  18. Was about to post this in the thread about Anthropic's one trillion $ valuation, but it's a bit of a different way of looking at things, so I figured I ask here. Re-emphasizing this is about Claude and Anthropic, so please, mod-bot, go eas…

  19. I've saw a 3D printed claude bot that jumps up and down when Claude wants your attention, so I decided to build something similar but using a raspberry Pi with a screen. https://i.redd.it/guv1jd60yl0h1.gif All the code is here: https://git…
