Philip Kiely, the software developer relations lead at BaseTen, dives into the realm of multi-agent AI. He advocates for building AI-native products through the composition of multiple models and agents that take action, moving beyond simple ChatGPT interfaces. Kiely highlights the shift to custom solutions driven by domain-specific needs and economic considerations. He emphasizes the importance of safety, trust, and iterative experimentation in AI engineering while discussing practical applications like a D&D assistant evolving into a multimodal agent.

Episode notes
Compose Models To Achieve User Goals
- Multi-model composition builds AI-native products beyond single-model wrappers.
- Composing models and tools lets systems achieve user goals, not just produce text.
Start With Off-The-Shelf Models
- Start with off-the-shelf models to explore what's possible quickly and cheaply.
- Move to custom solutions only after understanding product needs at scale.
Agentic AI Is Action, Not Just Text
- Agentic AI means moving from producing information to taking actions via tools or function calls.
- Agents request tool use and the product executes those calls to perform real actions.
