Anthropic's Katelyn Lesse & Angela Jiang: Building an Ecosystem, not a Walled Garden

Katelyn Lesse and Angela Jiang, leaders of Anthropic's developer platform, outline their strategy built on a "three-layer cake": knowledge, execution, and coordination. They emphasize moving towards advanced "strategies" or meta-harnesses that assign distinct jobs to tokens, fostering a robust and open AI ecosystem. The discussion covers empowering builders, setting industry standards, and Anthropic's nuanced approach to an open platform versus a walled garden, focusing on architectural soundness over infrastructure ownership.

Angela Jiang and Katelyn Lesse of Anthropic discuss their strategy for building a robust developer platform that supports both internal product development and external builders. Their vision is to move from foundational primitives towards higher-order abstractions, enabling sophisticated AI applications, particularly agents.

Anthropic’s Platform Vision & North Stars

Anthropic’s platform team, led by Lesse and Jiang, is responsible for both external-facing APIs and internal product infrastructure. They operate with two main north stars:

  1. Internal Focus: Provide maximum leverage for internal teams to rapidly ship
