    Our 239th episode with a summary and discussion of last week's big AI news!FYI: this one has pretty out of date news, I was traveling last week and failed to upload... apologies. Recorded on 03/25/2026Hosted by Andrey Kurenkov and Jeremie HarrisFeel free to email us your questions and feedback at andreyvkurenkov@gmail.com and/or hello@gladstone.aiRead out our text newsletter and comment on the podcast at https://lastweekin.ai/In this episode:OpenAI is discontinuing the Sora iPhone app and seemingly shutting down its video generation API, while retaining internal video world-modeling work; the move is framed as a compute- and focus-driven pivot toward coding and productivity agents, alongside a collapsed Disney Sora deal. Anthropic’s Claude Code/Cowork gains full computer control via keyboard/mouse/display, tied to the recent Cept acquisition, and Google’s Gemini rolls out background “task automation” on select phones for limited delivery/ride-share use. Cursor releases the cheaper, benchmark-strong Composer 2 coding model amid controversy over its Kimi-based origins and licensing attribution. Other items include Adobe Firefly custom model training, Luma’s Uni 1 image model, US contracting and legislative proposals affecting AI safeguards and state preemption, major chip/memory developments (Meta ASICs with Broadcom, Micron’s HBM-driven surge, Musk’s “Terra Fab”), robotaxi scaling, and research on monitoring agent misalignment, shutdown resistance, “consciousness cluster” preferences, and self-improving “hyper agents.”Timestamps:(00:00:10) Intro / BanterTools & Apps(00:01:48) OpenAI Discontinues Sora App, Shuts Down Video Generation Service and API - Bloomberg(00:07:12) Anthropic’s Claude Code and Cowork can control your computer | The Verge(00:13:15) Gemini task automation is slow, clunky, and super impressive | The Verge(00:19:44) Cursor Launches Composer 2 AI Model to Challenge OpenAI & Anthropic(00:28:28) Adobe’s AI image generator can now be trained on your own art | The Verge(00:29:40) Luma AI launches Uni-1, a model that outscores Google and OpenAI while costing up to 30 percent less | VentureBeatApplications & Business(00:32:41) Trump Contracting Clause Would Override AI Safeguards(00:40:00) Meta accelerates AI ASIC roll-out as Broadcom secures four-generation chip design deal(00:47:07) Micron revenue almost triples, tops estimates as demand for memory soars(00:50:54) Elon Musk Unwraps $25 Billion Terafab Chip-Building Project - CNET(00:56:40) Zoox to widen US robotaxi footprint with San Francisco, Vegas expansion(00:57:39) Waymo hits 170 million miles while avoiding serious mayhem | The VergePolicy & Safety(00:58:43) The White House just laid out how it wants to regulate AI | CNN Business(01:06:54) How we monitor internal coding agents for misalignment(01:12:30) Incomplete Tasks Induce Shutdown Resistance in Some Frontier LLMs(01:18:15) Summary: Mechanisms to Verify International Agreements about AI Development(01:23:09) Scoop: Anthropic meets with House Homeland Security behind closed doorsResearch & Advancements(01:24:24) Consciousness Cluster: Preferences of Models that Claim they are Conscious(01:30:22) HyperAgentsSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
