Estimate · moonshot-tokenizer-estimate · ≈3.85 chars/token Auto-counts as you type
This is a chars-per-token approximation, not a real tokenizer. Actual tokens vary by language, code density, and tool-call overhead — counts are typically ±10–20% off for English prose, more for code or non-Latin scripts. For exact billing, use the vendor's official tokenizer.

Frequently asked.
Practical pricing questions, separated from calculator assumptions and regional taxes.
Q · 01 Can I still call Kimi K2.5? +
No. Moonshot (Kimi) retired
kimi-k2.5 on August 31, 2026, and requests to it now fail. Moonshot (Kimi) names Kimi K3 as the replacement. The rates on this page are the last ones Moonshot (Kimi) listed, kept for reading old invoices and for estimating a migration.Q · 02 What is Kimi K2.5 priced at? +
Kimi K2.5 was last listed at
$0.6/M input, $3/M output, and $0.1/M cache-hit input. The Kimi pricing docs state that prices exclude applicable taxes.Q · 03 How does prompt caching work? +
Kimi supports automatic context caching for this model. Cache-hit input is billed at
$0.1/M instead of the fresh-input $0.6/M rate, and the calculator's default agentic blend assumes an 82% cache-hit rate.Q · 04 How is the effective price calculated? +
AI//COST uses the same 92/8 agentic blend everywhere. With an 82% cache hit rate, Kimi K2.5's effective blended cost is
$0.41/M.Q · 05 Does this include image and video input? +
Kimi K2.5 is documented as a native multimodal model with text, image, and video input. The pricing page bills consumed tokens, so extracted document, image, or video context should be treated as model input once passed into a request.
Q · 06 Is there a batch discount? +
Kimi documents BatchJob pricing separately from the live chat-completion model rows. This page stores the standard online inference price; batch economics should be modeled in a dedicated calculator variant when used.
Q · 07 Are taxes or regional surcharges included? +
No. The Kimi pricing page says listed prices exclude applicable taxes and that checkout applies tax based on jurisdiction. AI//COST stores the vendor USD token price before taxes.
Q · 08 How accurate is the tokenizer estimate? +
The browser widget uses a
moonshot-tokenizer-estimate chars-per-token estimate for English text. Actual billing comes from Kimi API usage fields and can differ for Chinese, code, images, video, or mixed-language prompts.
