## Resource

Hey yall, Alex here, writing this from sunny London, at the first ever AI Engineer conference in Europe! What a show we have for you today! First, let me catch you up on what’s important: Anthropic, this week announced a whopping $30B ARR up from 19B in Feb, while also telling us about Claude Mythos Preview their next gen HUGE model that they won’t release to the public (yet?) that finds crazy vulnerabilities in existing code bases. Apparently OpenAI will follow up with a similar non-public model soon. The Meta Superintelligence Lab led by Alex Wang finally showed what they were working on, Muse Spark , the smaller of their upcoming models on a complete new infrastructure ( MSL announcement , Simon Willison’s deep dive on the 16 hidden tools ). In other news: Z.AI released GLM 5.1 in OSS finally ( HF weights ), Seedance 2.0 finally available in US on Replicate, OpenAI testing out GPT-image-2 on LM Arena under codenames, HappyHorse from Alibaba takes the video crown, and Mila Jovovich (5th Element, Resident Evil) releases agentic memory plugin called MemPalace ( Ben Sigman’s transparent correction thread is worth reading). We had 5 guests today on the show, we kick off with @swyx the founder of AI Engineer and host of Latent Space. We then chatted with @petergostev from Arena (formerly LMArena) about Mythos and the compute wars, then Vincent Koc , the second most prolific contributor to OpenClaw , then our friends VB from OpenAI and Omar from DeepMind, both previously at HuggingFace. This is a busy busy show, and given the time-zones, I unfortunately don’t have time for a full weekly writeup, but as always, I will share the raw notes and post the video (lightly edited). ThursdAI - Highest signal weekly AI news show is a reader-supported publication. To receive new posts…
