Count tokens from a prompt or JSON payloadShow

Plain text, OpenAI Chat or Responses JSON, or Anthropic Messages JSON. A final assistant message or a response body counts as output. Counted in your browser; nothing is uploaded.

Counts use OpenAI's o200k tokenizer, so they are exact for GPT-6 and GPT-5 models, plus a few tokens of message framing. Other providers' tokenizers count the same text differently and do not publish a conversion factor; Anthropic says Claude models from 4.7 on produce about 30% more tokens than earlier Claude models. For an exact count on another model, paste one of its API responses: the usage it reports is shown above.

How the Qwen3.8 Max API Cost Calculator works

As of October 13, 2026, Qwen3.8 Max costs $2 per million input tokens and $6 per million output tokens. A request costs its input tokens × the input rate ÷ 1,000,000 plus its output tokens × the output rate ÷ 1,000,000; multiply by requests for the monthly bill.

cost = (fresh input × input rate + cached input × cache rate + (output + reasoning) × output rate) ÷ 1,000,000

This page uses the same method as the LLM API Cost Calculator, which explains each term and assumption in full.

Worked example

A chat feature on Qwen3.8 Max sending 3,000 input tokens and getting 500 back, 1,000 times a day.

  1. 1Input: 3,000 × $2 ÷ 1,000,000 = $0.006
  2. 2Output: 500 × $6 ÷ 1,000,000 = $0.003
  3. 3Per request: $0.009
  4. 4Per month: $0.009 × 1,000 × 30 = $270.00

$270.00 a month. Caching a fixed system prompt that makes up 80% of the input would bring it to about $270.00, and the batch API would halve either figure.

Frequently asked questions

How much does Qwen3.8 Max cost per million tokens?

$2 per million input tokens and $6 per million output tokens at Alibaba's standard rate. Alibaba publishes no cache discount for it. There is no batch discount. One rate covers its full 1 million-token context window.

Does caching lower Qwen3.8 Max's price?

Probably, but Alibaba does not publish the rate. Its pricing pages say cache hits on Qwen3.8 Max are billed at a rate shown only in the Model Studio console, not the usual 10% of input. This calculator therefore prices cached input at the full $2, which overstates the cost of cache-heavy work. Check the console before you budget.

How big a request can Qwen3.8 Max take?

Up to 1 million tokens of context, input and output together, though Alibaba publishes no separate limit on output. That is roughly 750,000 words of English. The calculator warns when a request will not fit.
