a16z · youtube · 2026-07-31
a16z Podcast hosts the co-founders of Decagon, a rapidly growing enterprise AI agent company, to discuss the realities of building production-grade AI at scale.
Key Insights
- Embracing Open-Source & Fine-Tuning: Decagon transitioned 90% of its inference workload from frontier APIs to open-source models. They argue that fine-tuned smaller models often outperform larger models in specific tasks while optimizing latency and cost.
- Beyond API Plug-and-Play: Production-grade enterprise AI requires far more than just calling frontier models, relying heavily on robust evaluation systems, fine-tuning, and forward-deployed engineering.
- Agents Building Agents: The conversation covers their internal tool, Duet Autopilot, which automates the creation and optimization of agent workflows.
- Business & Competition: They analyze "glass box vs. black box" approaches in enterprise sales and discuss why application-layer startups will continue to thrive alongside foundation model labs.
