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.”

 * Infrastructure and geopolitics cover Stargate data-center delays amid OpenAI/Oracle/SoftBank control disputes and cash concerns, and China’s plan to scale 7nm/5nm wafer output despite yield and tooling constraints.
 * Research and safety/policy discuss optimizer gains from masked updates, “deep thinking tokens” as a reasoning-effort signal, LLM attractor-state behaviors in bot-to-bot chats, mechanistic interpretability of counting/line-wrapping, methods to map task difficulty to human time horizons, plus Anthropic–Pentagon contract tensions, Anthropic’s report on distillation attacks (DeepSeek/Moonshot/Minimax), and OpenAI’s report on disrupting malicious use.

In this episode:

* Major model launches include Anthropic’s Opus 4.6 with a 1M-token context window and “agent teams,” OpenAI’s GPT-5.3 Codex and faster Codex Spark via Cerebras, and Google’s Gemini 3 Deep Think posting big jumps on ARC-AGI-2 and other STEM benchmarks amid criticism about missing safety documentation.

* Generative media advances feature ByteDance’s Seedance 2.0 text-to-video with high realism and broad prompting inputs, new image models Seedream 5.0 and Alibaba’s Qwen Image 2.0, plus xAI’s Grok Imagine API for text/image-to-video.

* Open and competitive releases expand with Zhipu’s GLM-5, DeepSeek’s 1M-token context model, Cursor Composer 1.5, and open-weight Qwen3 Coder Next using hybrid attention aimed at efficient local/agentic coding.

* Business updates include ElevenLabs raising $500M at an $11B valuation, Runway raising $315M at a $5.3B valuation, humanoid robotics firm Apptronik raising $935M at a $5.3B valuation, Waymo announcing readiness for high-volume production of its 6th-gen hardware, plus industry drama around Anthropic’s Super Bowl ad and departures from xAI.
