Anthropic has launched a fresh wave of Claude AI models, sparking a new pricing battle in the enterprise AI market. The latest release, Claude Sonnet 5, came out on June 30 and immediately lowered the cost to $2 per million input tokens and $10 per million output tokens through August 31. It now serves as the default model for both Free and Pro users, signaling a push to attract wider adoption with aggressive pricing.

The Claude lineup has become more complex with multiple tiers. Claude Opus 4.8 dropped in late May, keeping the previous $5 input and $25 output price but enhancing coding and safety abilities. Then, on June 9, Anthropic released Claude Fable 5, a "Mythos-class" model that sits above Opus and costs twice as much $10 per million input and $50 per million output tokens. This creates a wide 5x price gap between the lowest and highest tiers across the lineup, offering users options based on needs and budgets.

Export controls disrupt Fable 5 launch

Fable 5’s rollout faced a hiccup due to U.S. export controls, which temporarily limited its global availability. The restrictions were lifted in early July, allowing the model to be accessed again worldwide. This incident highlights the increasing regulatory scrutiny surrounding advanced AI technologies, which could influence how companies price and distribute their models.

Anthropic’s pricing moves come amid a broader trend of AI cost competition that could reshape how enterprises allocate budgets for AI tools. Lower prices for capable models like Sonnet 5 put pressure on competitors to adjust their offerings. The ripple effect might even extend into AI-related crypto tokens, where innovation and pricing dynamics often intersect.
