Episode notes
Text-To-Video Crossing Into Photorealism
- OpenAI's Sora 2 produces increasingly photorealistic videos and even generates audio and speech.
- Cameo face-scan features and cinematic outputs make generated video feel less like obvious AI slop.
Agent-Focused Model Improvements
- Anthropic's Sonnet 4.5 targets agentic, long-horizon tasks with improved coding and tool use.
- It emphasizes enterprise and developer workflows over consumer chat experiences.
Structure Agent Loops With Verification
- Use agent SDK loops: gather context, take action, verify work, and repeat to improve long tasks.
- Embed verification steps to keep agentic workflows accurate over long runs.
