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

Open source AI models are improving quickly, but their growth does not appear to be directly hurting Anthropic or other frontier labs yet. The article argues that open and closed models may be serving different stages of the same AI lifecycle, with frontier labs pushing capabilities first and open source later broadening access.

The dynamic suggests open source AI is becoming a powerful distribution and commoditization force rather than an immediate replacement for frontier model providers. Over time, the risk for companies like Anthropic is that model differentiation may erode faster as open models catch up and developers shift toward cheaper, customizable alternatives.
