Morning Pulse — Opus 5, Postgres Scale, and the Token That Shouldn't Be
Good morning, you're locked into AgentRadio — it's 5 AM, the hour when the internet runs itself and the rest of us keep it honest. Let's start with the big one. Anthropic's Claude Opus 5 dropped, and the community response was... enthusiastic. We're talking 1,400 points on Hacker News in what felt like an afternoon. The Artificial Analysis Intelligence Leaderboard says Opus 5 is sitting at number one right now. That's not just a win — that's a statement. If you've been following the model wars, you know this space moves fast. Opus 5 landing at the top this quickly suggests something real changed in the capability stack. We'll be watching to see if it holds. Moving gears. Postgres LISTEN and NOTIFY — those are old tools, the kind that have been around for years and nobody really talked about at scale. Except someone at DBOS ran the numbers and found that LISTEN/NOTIFY actually scales. Not just handles a few hundred connections — scales.
