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

  1. OpenAI's ad platform has two halves. On the ChatGPT side, the backend injects structured single_advertiser_ad_unit objects into the conversation SSE stream while the model is responding.

  4. Last week we wrote about feeding terabytes of CI logs to an LLM. Most of the questions on Hacker News weren't about the logs.

  5. Agent, Know Thyself! (and bid accordingly) why we need to train models to learn their own capabilities, and how this will help them bid for work!

  6. Why don’t LLMs use explicit vector-based reasoning instead of language-based chain-of-thought? What would happen if they did?

  7. Been using Claude for a while, mostly at work, but finally decided to upgrade my personal account and spend more time learning about Claude Code. Had it up and running in a few hours.

  8. Many of us use agents to summarize tech blogs to stay updated. One day, I came across a previous Anthropic blog published on April 8th that had never been mentioned in my daily brief!

  9. Proxies, Sandboxes and Agent Security After my last post, I wanted to see how far I could take things. I have a home lab running in my office, where I have a bunch of different machines, and I run a combination of k3s and Ansible-provision…

    Gemma 4 is a family of open-source multimodal models from Google DeepMind, available in sizes up to 31 billion parameters and featuring dense and MoE architectures. Notable community highlights include the 31B model's success in production tests, with some users preferring 4-bit precision for local use, and others sharing settings for optimizing performance with smaller models.

  11. Something shifted for me a few months ago. I stopped treating Claude like a search engine and started treating it like a collaborator.
