OpenAI: I wrote an AI textbook—how long until AI can write a better one?

After finishing an RLHF textbook, the author reflected that LLM progress in long-form nonfiction writing has stalled. Strong writing models such as GPT 4.5 and Kimi K2 already feel dated, while coding, math, and similar tasks are nearing superhuman levels. Models can fix typos and edit, but they are still disorganized and error-prone when structuring entire chapters, which the author believes prevents them from autonomously solving open scientific problems.

OpenAI: how AutoGPT uses AGENTS.md and skill gating to manage AI-generated pull requests

AutoGPT maintainers found that AI agents do not proactively read documentation, so they put instructions in AGENTS.md and skill files next to the code directories. Through gating mechanisms such as mandatory PR templates, test plans, CI coverage thresholds, and CLA signatures, they turned agent-submitted PRs from “unusable” into “usable but not aligned with the roadmap.” Because CLA signing requires a browser and OAuth flow, it is used as a “human detector” to distinguish humans from agents.
