Claude Sonnet 5 Pricing Made Permanent

The launch price for Sonnet 5, $2 per million input tokens and $10 per million output tokens, stays instead of rising after August 31.

Sonnet 5 stays at $2 per million input tokens and $10 per million output tokens, the rate it launched at in June
That rate was set to end August 31 and move to standard Sonnet pricing of $3 per million input and $15 per million output
Nothing about the model changes. This is a price commitment, not a new version
