Claude Sonnet 5's promotional pricing of $2 per million input tokens and $10 per million output tokens ends August 31, 2026 — standard pricing of $3/$15 per million tokens takes effect September 1. Anthropic also extended a temporary 50% weekly usage boost for Claude Code subscribers through August 19.
The Actual Numbers
- Promotional pricing (through August 31): $2 per million input tokens, $10 per million output tokens
- Standard pricing (from September 1): $3 per million input tokens, $15 per million output tokens
- That is a 50% increase on both input and output token costs once promotional pricing ends
- Claude Code's temporary 50% weekly usage boost for subscribers runs through August 19, separate from the token pricing change
Why This Matters More Than a Routine Price Update
A 50% increase in per-token cost is a meaningful line-item change for any team running Claude Sonnet 5 at production volume — the kind of increase that is worth modelling against your actual usage before it takes effect, not discovering on next month's invoice. Teams that built cost estimates around the promotional rate should re-run those numbers now.
What to Do Before September 1
Pull your actual token usage over the past 30–60 days and re-run your cost projection at the standard $3/$15 rate rather than assuming the promotional rate continues. If the increase materially changes your economics, this is also a reasonable moment to evaluate whether every current use case genuinely needs Sonnet-tier capability, or whether some workloads would perform acceptably on a smaller, cheaper model — the same right-sizing discipline that applies to cloud infrastructure spend applies just as directly to LLM API costs.
