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

Anthropic’s platform team is building a layered developer stack for both internal products and external builders, with a roadmap that moves from knowledge and execution to coordination strategies. The guests argue for an open ecosystem built on standards like MCP and interoperable sandboxes, while keeping harnesses tuned to Claude rather than treating models as freely swappable commodities.
