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

  1. [AINews] OpenAI reports median internal Codex output tokens grew 56x in Research, 32x in Customer Support, 27x in Engineering, and 13x in Legal since November 2025. It's happening.

  2. I analyzed 30+ of my own Opus ultra code sessions with Claude to understand how the dynamic workflow executes and where tokens were getting spent and identify any scope for savings. In ultra code mode Claude runs a task by writing determin…

  3. We introduce Autodata, a general method that enables AI agents to act as data scientists who build high quality training and evaluation data. We show how to train (meta-optimize) such a data scientist agent, so that it learns to create eve…

    Claude Opus 4.6, Anthropic's flagship model, saw its accuracy drop on the BridgeBench hallucination test from 83% to 68%, highlighting a significant regression in handling certain tasks. Meanwhile, biologists are revisiting cases of mushroom-induced hallucinations in China, suggesting ongoing research into natural causes of similar phenomena.

  6. Can a small group of volunteers shape how AI systems discuss animal welfare, just by editing Wikipedia? We show that they can.

  7. Reverse engineered some guys vibecoded OS. Wasn't mad about bad code, I was mad at the fact that he was charging 45-170$ for a claude code wrapper and people were actually buying it.

    OpenAI has released GPT-5.4-Cyber for testing as part of its Trusted Access for Cyber Defense program, aiming to compete with Anthropic's Claude Mythos in the cybersecurity domain. Meanwhile, concerns are rising over the potential risks associated with advanced AI models like Mythos, prompting calls for improved defenses before wider releases.

  11. In February 2024, Notion bought Skiff, an encrypted email and productivity software startup. Within a year, Notion shut down Skiff’s email service (taking @skiff.com email addresses with it).

  12. Agentic AI changes the unit of knowledge work from single interactions to delegated, long-horizon tasks. Chatbot interactions are often short and self-contained.

  13. Basically I came across 10k in AWS credits that I can use through Bedrock Services to spend towards Claude. I was thinking of building something with Fable 5 upon its return and was curious what people would like to see!

  14. Doctor and immunologist Derya Unutmaz has been interested in artificial intelligence for years. But his “aha” moment came in late 2025, when GPT‑5 Pro helped him and his lab revisit a three-year-old puzzle centered on a special type of imm…
