What is the cheapest Anthropic model?

Claude Haiku 5.5 is the lowest blended-price option among tracked active non-embedding models, or among all models if only embeddings are listed: $0.10 input and $0.50 output per million tokens ($0.20 blended). Blended pricing uses 75% input and 25% output for generation models; your cheapest option may differ with your workload.

Which Anthropic model has the highest AA Intelligence score?

Claude Opus 5.5 has the highest listed Artificial Analysis Intelligence Index score among tracked active Anthropic models: 57.6. This is one evaluation, not a guarantee of the best result for every task. Models without measured results are not ranked as zero.

How do I calculate monthly Anthropic API costs?

Multiply input tokens in millions by the input rate and add output tokens in millions multiplied by the output rate. For example, 20 million input and 5 million output tokens on Claude Haiku 5.5 cost an estimated $4.50 at the listed rates. This excludes tool charges, cache-specific charges, taxes and any endpoint-specific adjustments.

Which Anthropic model has the largest context window?

Claude Fable 5 has a listed context window of 1M tokens, the largest among tracked active Anthropic models. Context capacity and maximum response length are separate limits; verify both on the model page and in the endpoint documentation.

What is the latest Anthropic model in the catalog?

Claude Haiku 5.5 has the most recent listed release date among tracked active Anthropic models: 2026-10-07. Models without a usable release date are excluded from this comparison. Catalog release dates do not guarantee immediate API availability.

Do Anthropic models support image inputs?

17 tracked active models list image inputs, including Claude 3 Haiku, Claude Fable 5, Claude Fable 5.1. Accepting images does not mean a model generates images; check each model's separate input and output formats and endpoint limits.

Can prompt caching lower Anthropic API costs?

17 tracked active models have a listed cached-input rate, including Claude 3 Haiku, Claude Fable 5, Claude Fable 5.1. Savings depend on eligible repeated input and the endpoint's cache rules, duration and any write charges.

Do Anthropic models support tool calling?

17 tracked active models list tool-calling capabilities, including Claude 3 Haiku, Claude Fable 5, Claude Fable 5.1. Verify the exact tool schema and availability with your API endpoint before integrating.

How should I compare Anthropic benchmark scores and prices?

Compare scores within the same evaluation: Artificial Analysis Intelligence Index, DesignArena Elo, general Arena Elo and MMLU-Pro use different tasks and scales. Missing results are not zeroes. Pair a relevant measured benchmark with input/output pricing and tests of your own workload; the cheapest or highest-scoring model is not automatically the best fit.

Are retired Anthropic models included in the price list?

The price list shows active models by default. Turn on Show retired models to include retired catalog entries, where available. A retained model page preserves reference information, not a promise that its API is still available.

Is Anthropic an AI lab or an inference host?

Anthropic is categorized as an AI lab in this catalog. Individual model pages list available API hosts separately; model creator and API host are different roles.
