> Kimi
platform.kimi.com is the Kimi (Moonshot AI) open platform; the China-facing site quotes CNY while the published USD price list is at platform.moonshot.ai/docs/pricing/chat. Kimi K3 is listed at $3.00 per 1M input tokens (cache miss), $0.30 cached input and $15.00 output with a 1,048,576-token context; K2.7 Code is $0.95 / $0.19 / $4.00 and K2.6 is $0.95 / $0.16 / $4.00, both with 262,144-token contexts. The API is paid prepaid usage rather than subscription, and the only free grant documented is an exchange voucher of 15 CNY issued after identity verification, which the docs state cannot be spent on Kimi K3.
// pros
- Cache economics are stated explicitly: cached input is $0.30 per 1M tokens against $3.00 for a cache miss on K3, a 10x spread that rewards stable long prefixes.
- Context windows sit next to the price on the same table - 1,048,576 tokens for K3 and 262,144 tokens for kimi-k2.7-code, kimi-k2.7-code-highspeed and kimi-k2.6.
- File content extraction and file storage APIs are marked temporarily free (xian shi mian fei), so only the tokens consumed by the extracted text are billed.
- Search-tool rate limits are metered independently of chat limits and return X-RateLimit-Limit / Remaining / Reset headers on HTTP 429; two search endpoints count separately.
- The docs publish both OpenAI-style Chat Completions and Anthropic-compatible Messages endpoints plus a Batch API and a token estimation API, so integration can be validated before spend.
// cons
- The new-user voucher is 15 CNY and the documentation states it cannot be used to try Kimi K3 (K3 requires a top-up), so the flagship model has no official free trial.
- Vouchers do not count toward the cumulative top-up total that sets the rate-limit tier, so a voucher-only account stays at the lowest tier.
- Risk-control throttling is documented as permanent once triggered by anomalous account behaviour, with no stated appeal path.
- Billing is prepaid with no subscription plan: the docs state the API platform is pay-as-you-go and separate from Kimi membership products, so traffic stops at zero balance - the guardrails offered are a project daily budget and a default low-balance alert at 20 CNY.
Suited to long-context agent and coding workloads where prefix caching dominates the bill, since the cached-input rate is a tenth of the cache-miss rate. Set a project daily budget before pointing an agent at it, and pair it with a second provider rather than relying on it as a sole gateway given the prepaid balance model.

How we estimated this: the free allowance is converted to a dollar value using the provider’s own pay-as-you-go rates for the models a typical developer would reach for. When the allowance is metered in requests, tokens or minutes rather than dollars, we assume median usage of the cheapest capable model. Because assumptions are involved, the figure carries the est. flag — treat it as an order of magnitude, not a quote.
note: Official docs state a 15 CNY voucher is granted after personal or enterprise identity verification (platform.kimi.com/docs/guide/account-and-payments), converted at roughly 7.1 CNY/USD; the same page states the voucher cannot be used on Kimi K3.
| Plan | Type | Monthly | Input /1M | Output /1M | Note |
|---|---|---|---|---|---|
| Free tier (source-reported) | free | — | — | — | Not an ongoing free tier. New users who register and complete personal real-name verification receive roughly CNY 15 (≈$2.23) in one-off trial credits (time-limited), usable on the K2 family. The flagship K3 requires a prior top-up to unlock (community reports put the floor around CNY 10 (≈$1.49)), and the CNY 15 (≈$2.23) new-user voucher explicitly does not apply to K3. On the USD-priced side there is a promotional 'top up USD 5, get a USD 5 voucher' offer. Once credits are spent the platform is purely paid; no permanently free model is offered. |

$ Does Kimi have a free tier?
Yes — Kimi offers a free tier that we value at roughly $2.10 in free credits (estimate — derived from rate-limited usage at pay-as-you-go prices). Always confirm current limits on Kimi's official pricing page — free tiers change without notice.
$ How much does Kimi cost per 1M tokens?
Kimi does not publish simple per-1M-token pricing (it may bill per request, per output, or via a subscription plan). Check their official pricing page for exact figures.
$ Is Kimi safe to use?
Uprouter rates Kimi as low risk. Risk: medium. Pricing, model IDs, context lengths and rate-limit mechanics are documented on the official platform pages, and prepaid billing caps downside. The caveats are commercial rather than technical: the 15 CNY verification voucher is explicitly unusable on K3, vouchers do not raise your rate-limit tier, and anomalies trigger risk-control throttling that the docs describe as non-removable. Zero-data-retention is described as an enterprise option, so default API traffic is not covered by it. Risk ratings are editorial, evidence-based, and never influenced by affiliate relationships.

Uprouter runs its own probes; best-effort, not a guarantee. Probe results depend on our network location and cadence — for production, always use the provider’s own status page.

Confidence reflects how much verifiable evidence (official docs, probe history, community reports) backs this entry. Risk is our editorial assessment of operator reliability and terms — not financial advice.
