Claude API pricing, October 2026: every model per million tokens
Input, cached and output prices for every Claude model, Anthropic's list price next to ours, and what a chat turn and a long-document request cost on Opus, Sonnet and Haiku.
How the Claude API is priced
Claude API calls are billed per token, at three rates per million tokens: input, cached input and output. Output costs several times input on every Claude model, and cached input costs a fraction of it. There is no seat or plan price; a request costs its tokens times the rates of the model it named.
Every Claude model
12 Claude models, newest first. Each row shows our price and Anthropic's list price.

Two requests, worked
A chat turn of 2,000 input and 500 output tokens, and a long-document request of 50,000 input and 2,000 output. Both sizes are assumptions; nothing is counted at the cached rate.
| Model | Chat turn, list | Chat turn, here | Long document, list | Long document, here |
|---|---|---|---|---|
| Claude Opus 5.5 | $0.018 | $0.0072 | $0.24 | $0.117 |
| Claude Sonnet 5.5 | $0.009 | $0.0039 | $0.12 | $0.066 |
| Claude Haiku 5.5 | $0.0005 | $0.0002 | $0.006 | $0.0033 |
Input tokens times the input rate plus output tokens times the output rate, per million.
Claude Opus 5.5: $2.10 in and $6.00 out here, against $4.00 and $20.00 at list, 47% under on input and 70% on output.
Claude Sonnet 5.5: $1.20 in and $3.00 out here, against $2.00 and $10.00 at list, 40% under on input and 70% on output.
Claude Haiku 5.5: $0.06 in and $0.15 out here, against $0.10 and $0.50 at list, 40% under on input and 70% on output.
Cached input
When a request repeats a prefix the API has seen, such as a long system prompt or a document, the response reports those tokens as cached and they bill at the cached rate in the first table. A model with no cached rate bills them at its input rate.
Calling it
The Anthropic SDK takes a base URL and a key. Every Claude id in the table works with the same two values; the OpenAI SDKs work too.
from anthropic import Anthropic
client = Anthropic(
base_url="https://api.uplinkswitch.com/v1",
api_key="sk-uplink-live-...",
)
message = client.messages.create(
model="claude-opus-5-5",
max_tokens=1024,
messages=[{"role": "user", "content": "Summarize this in one line."}],
)
print(message.content[0].text)More in the SDK guide and the Claude Code guide.
Questions
Is there a subscription? No. Credit is prepaid from $10, and each top-up locks your prices for 30 days. New accounts start with $1 free.
Which Claude model should I use? The cheapest one that does the task. Haiku for short, high-volume work and subagents, Sonnet for most coding and writing, Opus where the harder answer is worth the price. Run the same prompt on each and compare.
Where is the full price list? On the Claude pricing page, and every other model on the Models page. To see what your own usage would cost, re-price an export on the savings page.
