Claude API pricing, without the Anthropic bill.
The Claude models cost 30% of Anthropic's official API price through Chernion, billed per token from a prepaid balance. There is an Anthropic Messages surface, so Claude Code and the Anthropic SDK point straight at it, and the OpenAI SDK works too.
Per million tokens, official struck through.
The faint figure is Anthropic's official list price. The bold figure is what you pay through Chernion, which is 30% of official for the Claude group. Rates are read live, so this table is always current.
| Model | Input / 1M | Output / 1M | Save |
|---|---|---|---|
Sonnet 4.6 sonnet-4.6 | $3.00$0.900 | $15.00$4.50 | −70% |
Haiku 4.5 haiku-4.5 | $1.00$0.300 | $5.00$1.50 | −70% |
Looking for the frontier Opus models? They sit in the premium group at 50% off on the full model list.
A fixed share of official, billed per token.
Every Claude model is billed at a fixed percentage of Anthropic's official API price, set by its group. The Claude group is 30% of official, so a model that lists at 3.00 per million input tokens costs 0.90 here. You pay per token for the input you send and the output you get back, with no subscription and no minimum.
- 1 million input tokens
- $0.900
- 1 million output tokens
- $4.50
- A 2,000 in and 500 out request on Sonnet 4.6
- $0.004050
Tokens are the unit of text the model reads and writes, roughly four characters each. You are billed for the input you send and the output you get back, nothing else.
Same SDK, same Claude, lower price.
- Point the base URL at the Chernion endpoint and swap in your key. Streaming and tool calls keep working.
- Use the Anthropic Messages surface for Claude Code, or the OpenAI Chat Completions surface, whichever your stack already speaks.
- Every reply returns its exact cost in a chernion field, so you always know what a Claude call cost.
- Top up the prepaid balance with crypto or a card, with no subscription and no minimum.
