Anthropic Pricing
Anthropic charges from $0.500 per 1 million output tokens, depending on the model. Claude Haiku 5.5 is the cheapest at $0.500/1M output and $0.100/1M input; its current flagship Claude Fable 5.1 costs $50.00/1M output. The largest context window is 1.0M tokens (Claude Fable 5). Prices are USD, current as of October 12, 2026.
Anthropic prices Claude in three tiers — Haiku for high-volume classification and extraction, Sonnet for general production work, and Opus for the hardest reasoning. Output tokens cost roughly 5× input across the lineup, so response length drives your bill far more than prompt size.

A dash in the batch column means our catalog carries no published batch rate for that model — not that the model has no batch tier. Batch coverage in the upstream pricing data is uneven.
Frequently asked questions
How much does Anthropic cost per 1M tokens?
Anthropic pricing starts at $0.500 per 1 million output tokens (Claude Haiku 5.5) across 28 models, with its current flagship Claude Fable 5.1 at $50.00. Older premium models in the catalog list higher. Rates current as of October 12, 2026.
What is the cheapest Anthropic model?
Claude Haiku 5.5 is the cheapest Anthropic model on both axes — $0.100 per 1M input tokens and $0.500 per 1M output. It is the right default for high-volume, low-complexity work such as classification, extraction and routing.
What is the largest Anthropic context window?
Claude Fable 5 has the largest context window in the Anthropic catalog at 1.0M input tokens, with up to 128K output tokens per response.
Does Anthropic support prompt caching?
Yes. Claude Haiku 5.5 reads cached input at $0.010 per 1M tokens, against $0.100 per 1M uncached. Caching pays off when a long system prompt or document is reused across many requests.
Does Anthropic offer batch pricing?
Yes — 21 Anthropic models in this catalog publish a discounted rate for asynchronous batch jobs, at 50% off output tokens. Claude Haiku 5.5 bills $0.250 per 1M output in batch against $0.500 synchronously. Batch trades real-time responses for the lower rate, so it suits backfills, evaluations and bulk enrichment rather than user-facing calls.
Which Anthropic models support reasoning or vision?
The Anthropic catalog includes 8 reasoning models, 8 vision models, 8 with tool calling. Reasoning models bill their internal thinking as output tokens, so they cost more per visible response than the headline rate suggests.
How do I calculate my actual Anthropic bill?
Multiply your input tokens by the input rate and your output tokens by the output rate, both per million, then add retries and any conversation history resent on each turn. Calcaas does this against your real usage pattern and shows the margin left at your price point.

What will this actually cost you?
Per-token rates only tell you half the story. Calcaas multiplies them by your real usage — prompt size, response length, retries and conversation history — then shows the margin left at your price point.
