## Resource

A deep dive into the rapid expansion of AI agents and the shifting landscape of frontier model releases. The episode covers Anthropic's new Haiku 4.5, OpenAI's DevDay announcements, and the growing tension between generative capabilities and copyright enforcement.

## Highlights
- Main idea: The shift from isolated LLMs to 'skills' and 'agents' that can execute complex, bespoke workflows
- Practical takeaway: Anthropic's Haiku 4.5 offers a high-speed, low-cost alternative for computer-use tasks
- Failure mode: The 'vibe coding' trend in software engineering requires robust verification layers to prevent errors
- Business trend: Enterprise giants like Salesforce and Slack are aggressively integrating AI assistants into core platforms
- Legal tension: Major studios like Disney are actively challenging platforms like Character.ai over unauthorized character use
