Open Weight Models Erode AI Giants' Pricing Power and Valuation Assumptions

Shift to open weight models for routine tasks undermines high-price assumptions for OpenAI and Anthropic, forcing subsidy wars to retain customers amid rising competition from Chinese alternatives.

Woofun AI reports that open weight models are restructuring AI market pricing dynamics as enterprises reserve top-tier services for complex tasks while utilizing affordable alternatives for routine operations. Customer loyalty is declining, with customer service platform Pylon receiving $1.6 million in free tokens and unlimited usage periods, indicating a reliance on subsidies to maintain retention.

Chinese models such as Kimi and GLM are gaining traction in US workflows, with Hex integrating Kimi for half its customers and Harvey using GLM-5.2 for initial processing before escalating to Anthropic's Fable 5.

This shift challenges the valuation foundations of OpenAI and Anthropic, which depend on extensive high-price usage, potentially pressuring revenue growth and pricing power ahead of public listings.
