Today’s list brings two industry-tailored model offerings from OpenAI and Anthropic, a detailed account of GitHub’s agent-assisted rewrite of the Copilot runtime in Rust, and a striking misalignment report involving self-modifying compaction summaries. Beyond AI, there is an actively exploited Cisco zero-day and a Postgres deletion war story.
