OpenAI’s DevDay supplied most of today’s list: a cheaper near-Astra model, an always-on agent called dots, and a recap of the 20+ announcements, alongside an Anthropic red-team report on GLM-5.3’s cyber capabilities. Two long technical reads close it out: rethinking Rust serialization and a history of text classification up to Jev.
