US dollars per million tokens, list rates on Moonshot (Kimi)'s own API. Cache read is the price of a cached input token. Batch is the asynchronous API, where the vendor offers one. The date in each row is when we last read it on the vendor's pricing page; it links to that page.

§ 02 / MONTHLY COST

Kimi API monthly cost estimates

What light use (10M input + 2M output tokens a month), medium use (100M input + 20M output tokens a month), heavy use (1B input + 200M output tokens a month) costs on each current model, at list price with no caching and no batch discount.

Model Input / output per 1M Light · 10M + 2MMedium · 100M + 20MHeavy · 1B + 200M
Kimi K3.1 Pro $2.00 / $10.00 $40.00$400$4,000
Kimi K3 $3.00 / $15.00 $60.00$600$6,000

Prompt caching and the Batch API cut these figures; the next sections show by how much. For your own token counts, use the LLM API cost calculator.

Kimi API pricing FAQ

Practical questions about Kimi K2, open weights, and long context.

Q · 01

Which Kimi model should I start with?

+
Kimi K3.1 Pro ($2.00/$10.00), Moonshot's flagship since October 24, 2026, with a 1M context - cheaper than the K3 it replaces at the top ($3.00/$15.00), which stays on sale. Kimi K2.6 and Kimi K2.7 Code ($0.95/$4.00) are still the cheapest Kimi rates, but they close to new users on October 31, 2026 and are planned to retire by the end of December. See the use case picker above.
Q · 02

Are Kimi models really open-weight?

+
Yes. Kimi K3 (2.8T parameters, which Moonshot calls the first open-source 3T-class model) and the Kimi K2 line (1T-parameter MoE, ≈32B active, Modified MIT license) are published on Hugging Face and self-hostable. Moonshot says Kimi K3.1 Pro's full weights follow by November 4, 2026.
Q · 03

What is Kimi's long-context heritage?

+
Kimi made its name in 2023 by handling roughly 200,000 Chinese characters per conversation — far longer than rivals at the time. Kimi K3 and K3.1 Pro offer a 1M-token window (the K2 models 262K), and the API's automatic context caching cuts cache-hit input to a fraction of the base rate, which matters for long documents.
Q · 04

Where is my data stored?

+
The direct Kimi Platform API is China-based, so data is processed under Chinese data rules. US export-control and procurement questions apply for some buyers. Because K3 and K2 weights are open, and the API now offers Zero Data Retention, the cleanest workaround for data control is to self-host them on your own US/EU infrastructure.
Q · 05

What happened to the older K2 preview models?

+
The dated K2 previews — kimi-k2-0711, 0905, Turbo, and Thinking — retired on May 25, 2026. Kimi K2.5 followed on August 31, 2026, together with the whole Moonshot V1 line (8K, 32K, 128K, moonshot-v1-auto and the vision previews). Moonshot now points every retired model to Kimi K3.1 Pro, and the remaining K2 models - K2.6 and K2.7 Code - close to new users on October 31, 2026, with retirement planned by the end of December.
Q · 06

How does Moonshot compare to DeepSeek and Qwen?

+
Versus DeepSeek, Kimi K2 matches the open-weight frontier pitch but adds native multimodality (DeepSeek is text-only). Versus Qwen, Moonshot offers fewer sizes but a single very large 1T-parameter open MoE plus its long-context pedigree.
§ 08 / ABOUT

About Moonshot (Kimi)

www.moonshot.ai →

Moonshot AI (月之暗面) was founded in March 2023 in Beijing by Yang Zhilin (a former Meta AI and Google Brain researcher) with Tsinghua University schoolmates Zhou Xinyu and Wu Yuxin. Its consumer assistant, Kimi, launched in October 2023 and built its reputation on very long context — handling roughly 200,000 Chinese characters per conversation, well ahead of peers at the time.

Moonshot's technical signature is the Kimi K2 line: a 1-trillion-parameter mixture-of-experts model with ~32B active parameters, trained with the lab's own MuonClip optimizer and released as open weights (Modified MIT) on Hugging Face. K2.5 (January 2026) added native multimodality via a MoonViT vision encoder, and K2.6 (April 2026) shipped variants from quick chat up to large multi-agent swarms. Kimi K3 (July 2026) moved to a 2.8T-parameter open-weight model with a 1M-token context, and Kimi K3.1 Pro (October 24, 2026), a post-trained K3, became the flagship at a third below K3's price.

Funding has been rapid: an Alibaba-led $1B round in February 2024 (at a $2.5B valuation), rising to a $2B raise at a ~$20B valuation in May 2026 led by Meituan's Long-Z, with Tencent, HongShan, China Mobile, and others among its backers — making Moonshot one of China's top-funded LLM startups.

Pricing on the Kimi Platform is competitive, and the API offers automatic context caching that drops cache-hit input to a fraction of the base rate — meaningful for long-context workloads. The catalog keeps consolidating: the dated K2 previews retired on May 25, 2026, K2.5 and the Moonshot V1 line on August 31, and the remaining K2 models close to new users on October 31, 2026, with retirement planned by the end of December.

The trade-offs: Kimi is China-based, so the direct API stores data under Chinese rules — though the open weights let you self-host anywhere. Versus DeepSeek it competes directly on open-weight frontier quality; versus Qwen it offers fewer model sizes but a distinctive 1T-parameter open MoE and long-context pedigree.
