Why the rise of open source AI isn’t hurting Anthropic … yet
Open source models’ success isn’t coming at the expense of frontier labs. Instead, they each seem to capture two phases of the same life cycle.

Open source AI models are becoming more popular, but expensive frontier AI models from companies like Anthropic are not losing market share as quickly as might be expected. According to data from infrastructure platforms, cheaper open source models are handling more token volume, yet frontier models still capture the majority of spending because they charge significantly higher prices per token. The theory explaining this is that frontier models are used to develop and prove new use cases, which then migrate to cheaper open source alternatives as they mature, while new use cases continuously emerge to sustain demand for expensive frontier models. This two-tiered system, where frontier labs handle early-stage development and open source handles production, may become a stable feature of the AI economy.
