Claude Sonnet 5 Pricing Deadline for Canadian Teams
Anthropic launched Claude Sonnet 5 as a more agentic Sonnet: plans, tools, browsers, terminals, and longer follow-through at a price built for daily volume. The part most Canadian ops teams miss is the intro window.
From September 1, 2026: $3 / MTok input · $15 / MTok output
What Sonnet 5 is for
Anthropic positions Sonnet 5 as the agentic Sonnet that narrows the gap to older Opus-class work at lower cost. It is the default model on Free and Pro plans, available on Max / Team / Enterprise, Claude Code, and the Claude Platform. API ID: claude-sonnet-5.
- Multi-step coding and tool use without jumping straight to Opus
- Day-to-day automation that used to stall on Sonnet 4.6
- Effort controls for cost/performance tradeoffs
- Cyber safeguards on by default (stricter than pure cyber work paths)
Price table (API, USD)
| Window | Input / MTok | Output / MTok |
|---|---|---|
| Through Aug 31, 2026 (intro) | $2 | $10 |
| From Sept 1, 2026 (standard) | $3 | $15 |
| Batch (intro period) | $1 | $5 |
| Batch (standard period) | $1.50 | $7.50 |
Anthropic also notes Sonnet 5 uses an updated tokenizer. The same text can map to roughly 1.0–1.35× more tokens depending on content. Intro pricing was set to keep the transition roughly cost-neutral versus older Sonnet. After Aug 31, measure real token logs, not last quarter’s Sonnet 4.6 invoices.
Where Sonnet 5 sits vs Opus 5 and Fable 5
| Model | Sticker (standard) | Role |
|---|---|---|
| Sonnet 5 | $3 / $15 (after intro) | Default daily agent + coding volume |
| Opus 5 | $5 / $25 | Heavier production agents |
| Fable 5 | $10 / $50 | Hardest multi-day Mythos-class jobs |

What Canadian teams should do before Aug 31
- Export usage by model for the last 30 days.
- Tag workflows: daily / agent / hard-job only.
- Set Sonnet 5 as default for volume paths while intro lasts if quality passes your tests.
- Rewrite budgets for Sept rates (+50% sticker on $2→$3 and $10→$15).
- Turn on caching and batch for repeated system packs and overnight jobs.
- Train staff so retries stop doubling token burn.
