Anthropic renegotiated its partnership with Amazon to alter how the tech giant pays for artificial intelligence models. The new structure bills Amazon based on tokens consumed rather than computing hours used. This change reflects Anthropic's growing leverage as demand for enterprise AI models increases.

The pricing shift could significantly raise Amazon's spending on Anthropic technology. However, an Amazon spokesperson denied that the new agreement will increase costs for the company.

The development follows an expanded strategic collaboration formed in April 2026. That agreement includes a potential multi-billion dollar investment from Amazon. It also requires a major cloud computing commitment from Anthropic.
