Why the rise of open source AI isn’t hurting Anthropic … yet

Decagon CEO Jesse Zhang argues that mature AI deployments are switching to lighter open source models, yet spending on expensive frontier models like Claude hasn't dropped. His theory: they aren't competitors but two phases of the same lifecycle—frontier models prove out use cases, then cheaper open source alternatives take over as those use cases mature. New use cases keep emerging, so frontier spend holds steady. The post doesn't provide Anthropic's specific revenue figures to back this up.

Why it matters: The insight is substantive and counterintuitive, but the source is a single CEO interview without multi-source data verification, and the post doesn't provide specific Anthropic revenue or retention numbers, so it stays at the 72 featured threshold.
