Budget flagship (Oct 7, 2026), replacing Haiku 4.5 at a tenth of its price. Rates shown are for prompts up to 100K tokens: a prompt over 100K bills the whole request at $0.50/$2.50, and cache reads and writes count toward the threshold. Cached read $0.01 (0.1x input), 5m cache write $0.125, 1h cache write $0.20, all 5x above 100K. Batch $0.05/$0.25 ($0.25/$1.25 above 100K). Ties GPT-6 Luna's $0.10/$0.50 on short prompts. Newer tokenizer counts the same text as ~30% more tokens than Haiku 4.5. 128K max output (300K on the Batch API, beta). Adaptive thinking, default effort medium.

Claude pricing FAQ

What is the cheapest Claude model?

Claude Haiku 5.5 is the cheapest current Claude model, at $0.10 per million input tokens and $0.50 per million output tokens, or $0.050 / $0.25 with the 50% batch discount.

Which Claude model should I use?

Pick the tier that fits the job, then the cheapest model in it. For the hardest work, flagship models: Claude Opus 5.5, Claude Opus 4.7 and Claude Fable 5.1 (from $4.00 / $20.00 for Claude Opus 5.5). For everyday work, mid-tier models: Claude Sonnet 5.5 ($2.00 / $10.00). For high-volume, simple jobs, budget models: Claude Haiku 5.5 ($0.10 / $0.50). Prices are input / output per million tokens. Tiers group models by capability, not price, so price your own workload in the calculator on this page.

Does Claude offer batch or caching discounts?

Batch: 50% off input and output on all 5 current models, so Claude Haiku 5.5 drops from $0.10 / $0.50 to $0.050 / $0.25 per million tokens. Prompt caching: reading cached input costs 2.5% to 10% of the input price on 4 of 5 current models; Claude Haiku 5.5's $0.10 input falls to $0.010 per million tokens when read from the cache.

What context window do Claude models have?

All 5 current Claude models have a 1M-token context window. A request's prompt and its output together must fit in the window.

What does the Claude API cost per person each month?

It depends on how much each person uses it. At list prices, an occasional user (3 short requests a working day) costs about $0.013 a month on Claude Haiku 5.5, and a daily power user (40 longer requests a day) about $24.64 on Claude Sonnet 5.5. The cost-per-seat calculator works it out for a whole team.

How often do Claude API prices change?

We check Anthropic's pricing page every day, and last re-verified every price on 5 Nov 2026. Since Feb 2026 we have recorded 2 price cuts and 1 price rise on Claude models, the latest on 7 Oct 2026, plus 9 launches. The price history chart on this page shows how each tier has moved.
