Exploring Claude Fable 5’s impact, Siri AI’s latest enhancements, and the competitive IPO landscape shaping AI’s future

Jul 21, 2026

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 248th episode with a summary and discussion of last week’s big AI news!

Recorded on 06/12/2026

Note: we recorded just before the OTHER big news about Fable... we’ll discuss it on the next episode.

Hosted by Andrey Kurenkov and Jeremie Harris

In this episode:

Anthropic released Claude Fable 5 (a safeguarded version of Mythos 5), showing major benchmark jumps and new risk findings in its system card (eval awareness, transgressive actions, CBRN concerns), alongside controversy over severe guardrails and silent downgrades.
Apple announced Siri AI at WWDC, positioning a more capable conversational assistant integrated across iPhone features, reportedly built on a custom Gemini partnership; Google also rolled out Gemini 3.5 Live Translate and cut Google AI Plus pricing while bundling more storage.
Business and infrastructure updates include OpenAI’s confidential IPO filing amid an IPO race with Anthropic and SpaceX, Bezos-backed Prometheus raising $12B for “physical AI,” DeepSeek seeking a major external round, and Google paying SpaceX about $920M/month for GPUs.
Open-source, safety, and policy developments feature new Gemma 4 and Diffusion Gemma releases, a lab letter urging DNA/RNA screening laws, Amodei calling for an FAA-like AI regulator and third-party testing, research on agent harms and RL “societal hacking,” and a dispute over music-label settlements with Suno/Udio.
