Standard	$5	$25
Cache hit / refresh	$0.50	—
5m cache write	$6.25	—
1h cache write	$10	—
Batch API	$2.50	$12.50
Fast mode (research preview)	$10	$50
US-only inference (`inference_geo: us`)	1.1× on token rates

Fast mode is first-party Claude API only. It is not the default path for most Alberta SMBs.

Opus 5 vs the rest of the stack

What Canadian teams should actually do

Stop mixing models at random. Pick a default (usually Sonnet 5 or Opus 5) and write a short policy.
Route by job, not hype. Quotes and email → Sonnet. Multi-step coding agents → Opus 5. Multi-day research / hard migrations → Fable 5 when budget allows.
Turn on prompt caching for system prompts and large document packs. Cache hits are 0.1× base input.
Batch non-urgent work for 50% off when latency does not matter.
Train the humans. Model upgrades fail when staff paste client data into public chats. Start free or book a live class.

Privacy and Canadian operations

US-only inference exists at a 1.1× multiplier for Claude 4.6+ models on supported surfaces. That is a residency control, not a full PIPEDA program. You still need rules for client files, municipal data, and who approves external AI output. Public Fable traffic can hit safety fallbacks (some cyber/bio topics route to lower models). Design agents assuming fallbacks can happen.
