New Models, IPO Announcements, and the Rise of Open Source Competitors
Note from Last Week in AI (Andrey): I’m back! And i’m sorry for putting the substack on a silent pause, work got a bit too overwhelming so I fell behind on this. I’ll do my best to resume normal posting, starting with catching up on podcast episodes missing from here (which are not last week… but I guess I should post them still, sorry for the spam!)
I’ve also paused paid subscriptions until I can get back to consistent posting. Apologies for the flakiness, and thanks for being a subscriber!
Our 247th episode with a summary and discussion of last week’s big AI news!
Recorded on 06/03/2026

In this episode:
Anthropic released Claude Opus 4.8 with improved benchmark scores, discussed eval-awareness findings and welfare/corrigibility themes from its system card, and introduced Dynamic Workflows for long-running multi-agent tasks.
Microsoft unveiled the always-on Microsoft Scout assistant built on OpenClaw plus new in-house MAI models (including MAI Thinking 1) and “frontier tuning,” emphasizing enterprise security architecture and model-from-scratch capability.
Major business moves included Anthropic’s $65B Series H at a $965B valuation alongside an IPO filing, a JPMorgan analysis arguing OpenAI needs major revenue growth to justify infrastructure spend, and Cognition raising $1B at a $25B valuation.
Policy and security highlights covered Trump’s voluntary pre-release government testing framework for powerful AI, Meta AI support being exploited to hijack Instagram accounts, tightened US Nvidia export controls and China’s travel approvals for AI experts, plus expanded Glasswing/Mythos-style cyber and biodefense initiatives.
