# Last Week in AI #250 - Mythos Mess, GPT 5.6-Sol, GLM 5.2 > Source: > Published: 2026-07-21 11:03:19+00:00 # Last Week in AI #250 - Mythos Mess, GPT 5.6-Sol, GLM 5.2 [Last Week in AI](https://lastweekin.ai) Anthropic's AI treaty discussions, US government's influence on AI model releases, OpenAI's processor development, memory market impacts, and more! 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 250th episode with a summary and discussion of last week’s big AI news! Recorded on 06/27/2026 Note from Andrey: sorry this is late again! this episode release somehow didn’t save and I only realized late, my bad... next one will be out way sooner!
