Our 252th episode with a summary and discussion of last week's big AI news! Recorded on 07/11/2026 Hosted by Andrey Kurenkov [https://twitter.com/andrey_kurenkov] and Jeremie Harris [https://www.linkedin.com/in/jeremieharris/] Feel free to email us your questions and feedback at andreyvkurenkov@gmail.com and/or hello@gladstone.ai [hello@gladstone.ai] Read out our text newsletter and comment on the podcast at https://lastweekin.ai/ [https://lastweekin.ai/] In this episode: * OpenAI publicly rolled out GPT-5.6 (including Sol and Luna) and rebranded its desktop agentic coding product as ChatGPT Work, amid disputed claims about whether the US government effectively green-lit and delayed the release and concerns about inconsistent, ad hoc frontier-model oversight and jailbreakability. * New model releases intensified pricing and capability competition: SpaceX AI’s Grok 4.5 launched as a very low-cost, Opus-class coding model with minimal safety documentation, while Meta released Muse Spark 1.1 with aggressive pricing, large coding/cyber benchmark gains, and a lengthy safety evaluation. * Meta also previewed Muse Video and rolled out Muse Image before quickly backtracking after backlash over easy generation of images of public Instagram accounts; separately, Chinese open-source models grew to over 30% of weekly OpenRouter tokens as cost pressure increased, alongside discussion of risks like potential insider threats. * Infrastructure, policy, and safety developments included Meta exploring selling AI compute as a cloud business, US energy regulators pressing grid operators on large-load data-center connections, Anthropic publishing a “global workspace” interpretability method for verbalizable internal representations, reports that China may restrict overseas access to top models, and AI 2040 proposing US–China coordination to slow progress until alignment improves.
