Notes

ADDED 2026-10-08, read directly from platform.claude.com/docs/en/about-claude/pricing. Positioned for high-volume, latency-sensitive work: classification, extraction, routing. STANDARD: input $0.10 / output $0.50 / cache write 5m $0.125 / cache write 1h $0.20 / cache read $0.01 per MTok. Batch API halves input and output to $0.05 / $0.25. US regional endpoint bills at 1.1x. Context window 1M at standard pricing, stated explicitly on the page. PRICED BY PROMPT LENGTH — A NEW DIMENSION. The $0.10 input rate applies to prompts UP TO 100,000 tokens. Prompts above 100,000 tokens pay a higher rate, which this schema has no field for. The stored figure is therefore the sub-100k rate and will understate cost for long-prompt workloads. Flag for Khaled: the calculator may need a long-prompt tier for this model. CACHE READ IS 10%, NOT 5%. The 5% cache-hit rate introduced with this generation applies to Opus 5.5 and Sonnet 5.5 ONLY. Haiku 5.5 keeps the older 10% convention: $0.01 is 10% of $0.10. Do not 'correct' this to 5%. VERSUS HAIKU 4.5: Haiku 4.5 is $1 / $5, so the published rates are 90% lower on both input and output. Anthropic's own launch post described Haiku 5.5 as 'on average 75% cheaper than Haiku 4.5'. The gap between 75% and 90% is unexplained from the pricing page alone — it may be a blended figure across caching, batch or mixed prompt lengths, or it may account for the above-100k rate. Treat 90% as the published-rate comparison and do not cite 75% as if it came from the price table. Haiku 4.5 remains listed and is NOT deprecated.
