Kimi K3.1 Pro uncensored pricing, with worked costs
Kimi K3.1 Pro Outlaw costs $7.50 in, $0.80 cached and $37.50 out per million tokens. Those are the prices billed, to the token, and the worked examples below are what each job actually costs.
Worked costs
| Job | Tokens | Cost |
|---|---|---|
| A chat turn | 2,000 in, 800 out | $0.0450 |
| A long answer | 5,000 in, 20,000 out | $0.7875 |
| A 25-turn agent session | 750,000 in (85% cached), 25,000 out | $2.29 |

Cached input is the prompt a model has just seen, sent again: an agent's history, a long system prompt, the files it keeps re-reading. It bills at $0.80 per million instead of $7.50, and coding agents send mostly cached input, which is why the agent session costs less than its size suggests.

Keeping a lid on it
Every key can carry a hard spend cap, and a request that could run past it has its max_tokens lowered to what is left, so a runaway agent stops at the cap rather than after it. See per-key spend caps. There is no subscription: credit is bought up front and spent per token.
