Stronger long-run coding, tool use, and debugging at $2 per million input tokens and $10 per million output — before an August step-up to $3/$15.
Anthropic has released Claude Sonnet 5, pitched at stronger long-run coding, tool use, and debugging. Launch pricing is $2 per million input tokens and $10 per million output tokens, moving to $3/$15 after August 31, 2026.
The headline is the price. A frontier-grade coding model at $2/$10 puts more pressure on the token economics that everyone downstream depends on.
Price is the weapon now. Sonnet 5 at $2/$10 signals a race to the bottom on raw tokens — which means durable value migrates up, to orchestration, distribution, and the workflows that decide which model gets called at all.
