Is Kimi AI Free? Pricing, Free Plan & Limits (2026)
Is Kimi AI Free? Pricing, Access, and What You Get in 2026
Short answer (verified June 2026): Yes, Kimi AI is free to use. Moonshot AI offers a free plan called Adagio with unlimited basic chat, file upload, and web access — and you can try kimi.com without even making an account. What's not free: heavy agent and deep-research usage, the Agent Swarm and Kimi Code tools, and the developer API, which is billed separately. Paid plans start at Moderato, $19/month (about $15/month billed annually). Pricing and quotas change often. The figures below were checked in June 2026 — always confirm the current numbers on Kimi's official pricing page before you subscribe.
Hey, Anna here. I opened kimi.com after hitting my ChatGPT free-tier cap for the third time in a week. I wasn't trying to switch tools — I just needed to finish a 60-page PDF without getting cut off. Someone had told me Kimi was "free, no limits, huge context window," and that's usually exactly where the catch hides.
There is a catch. It's just smaller and more specific than I expected. If you're a casual user who wants to chat, upload files, or work through long documents, the free plan genuinely covers you. The things behind the paywall are the heavy, developer-and-power-user features. Here's the full breakdown, kept deliberately durable — because the answer to "is Kimi free" stays the same even as the exact quotas shift month to month.
The Short Answer, in a Bit More Detail
Kimi runs on a five-tier membership system named after musical tempos. The bottom tier, Adagio, costs nothing and doesn't expire. It gives you unlimited basic conversations — that part is consistent across every source I checked, and Moonshot describes the chat experience itself as free on both kimi.com and the mobile apps.
What you're really deciding when you consider paying isn't "free vs. not free." It's whether you bump into the ceilings on the free plan often enough to care: the caps on agent runs, deep-research queries, and coding tools. For most people doing documents, drafting, and Q&A, you won't.
What's Free on Kimi.com and the Kimi App
Basic Chat With No Daily Message Wall
Unlike the ChatGPT free tier — which caps your higher-model messages before dropping you to a lighter model — Kimi's free plan lets you keep having standard text conversations without a hard daily message wall. You can open kimi.com and start typing with no account at all. Sign in (phone or Google) only when you want to save chats or unlock more.
The mobile apps on iOS and Android follow the same structure: free access, standard chat, no message wall for ordinary conversations.
File Upload, Long Context, and the Current Model
File upload works on the free tier, and it's the single biggest reason people try Kimi — you can drop in a long PDF and actually work through it without the document getting truncated halfway. Image input works too.
One correction worth making, because a lot of older write-ups (including an earlier version of this one) got it wrong: the latest flagship model is not locked entirely behind the paywall. Moonshot's own materials state that Kimi K2.6 is free to use through kimi.com and the app. What the free plan limits isn't the model — it's how much heavy work you can run on it: agent tasks, deep research, and coding workflows draw on a metered quota. For details on how the model itself is offered, the Kimi K2.6 pricing page is the first-party reference. (The model line moves fast — K2.5, then K2.6, and a coding-focused K2.7-Code arrived in June 2026 — which is exactly why it's worth checking the official page rather than trusting any fixed claim.)
How "Free" Actually Works: The Credit System
Here's the part that reframes the whole "unlimited" question. Basic chat is unlimited, but Kimi's heavier features — agent runs, deep research, coding — draw from a unified credit pool that's metered by token usage. A quick chat costs little; a deep-research report or a multi-step agent task costs a lot more. Credits refresh on a cycle and generally don't roll over.
So "free" is honest, but it has a shape: unlimited for talking and reading, quota-limited for the expensive autonomous stuff. That's the mental model to carry, and it's more durable than any specific credit number — which is exactly why I'm not going to quote you a daily allowance that could change next month. For the current quotas, the live numbers sit on Kimi's Help Center.
What Costs Money
The Paid Membership Tiers
All five tiers, top to bottom, with monthly pricing (annual billing runs cheaper):
The jump from free to Moderato ($19/month) is the one most people weigh. It raises your agent and deep-research quotas, adds priority access during peak hours, and unlocks Kimi Code. For comparison, ChatGPT Plus and Claude Pro both sit at around $20/month — so Kimi's entry tier is in the same ballpark, just pointed at agentic and long-context work rather than ecosystem breadth.
The API (Skip This If You're Not Building Something)
The developer API is completely separate from the consumer app. A membership doesn't include API calls, and API credits don't cover your chat usage. There's no permanent free API tier, and you fund the account before you use it.
As a rough reference, K2.6 lists at around $0.60 per million input tokens and a few dollars per million output tokens, depending on provider and version — meaningfully cheaper than the comparable Western frontier models, which is why developers have been paying attention. Because these rates vary by host and change frequently, treat any number as a planning estimate and check the live rate; Kimi K2.6 on OpenRouter shows current per-provider pricing in one place.
One Caveat on "Free": Personal Use
Worth flagging before you build anything on top of it: Kimi's consumer terms describe the service as intended for personal, non-commercial research and study use unless otherwise permitted. "Free to use" and "free to use in your commercial product" are not the same statement. If you're planning anything commercial, read the current terms of service rather than assuming the free chat extends to business use — this is the kind of clause that quietly matters later.
Free Access Compared — Kimi vs ChatGPT vs Claude
Kimi's real edges on the free tier are the lack of a daily message wall, the long context window, and the fact that you can try it without an account. The trade-off is that the agentic and deep-research features — the things that make Kimi distinctive — are the ones metered fastest on the free plan.
Hidden Costs and Access Pitfalls
Sign-up friction. You can use kimi.com with no account for basic chat. To save conversations or unlock more, you sign up — and SMS verification for non-Chinese numbers can be flaky on the website. The reliable workaround people report: install the mobile app, verify there, then scan the QR code on desktop to log in. Google login is also available.
Regional differences. The web app works globally and the apps are in international stores, but SKUs and pricing differ by region — the China-domestic version uses different tiers and yuan pricing. International plans are billed in USD and may not mirror the domestic feature set exactly.
Language polish. Kimi handles English fine for core chat, but it's a Chinese-origin product; documentation and support are most polished in Chinese. You'll notice the gap in help docs and support responsiveness more than in the chat itself.
Data location. Moonshot is a Chinese company and data is subject to its privacy policy. As with any AI chat, don't paste passwords, financial details, or sensitive personal information regardless of which tool you're using.
Should a Casual User Pay for Anything?
Probably not right away. The free plan genuinely covers long-document reading and summarization, standard drafting and Q&A, and uploading files you want to analyze. Those are most people's daily use, and the free tier handles them without a credit card.
You'd feel the ceiling if you start leaning on deep-research mode, run agent tasks regularly, or want Kimi Code for programming. That's where Moderato at $19/month becomes the entry point. My honest take: use the free plan for a week first. The context-window advantage over free ChatGPT is real and immediate. Whether the agentic features justify paying depends entirely on what you're actually trying to do — and you'll know within a few days.
FAQ
Is Kimi AI really free, or is it a trial?
It's a real, permanent free plan (Adagio), not a countdown trial. Basic chat access has stayed free consistently. Specific features do move between tiers over time, so the boundaries of "free" shift even though the free plan itself stays.
Do I need a Chinese phone number to sign up?
No. International numbers work, though website SMS delivery can be unreliable — verify in the mobile app first if it fails, or use Google login.
Does the free plan use the latest model?
Largely yes for chat — Moonshot offers the current model on kimi.com and the app for free. What's limited on the free plan is the volume of heavy agent, research, and coding work you can run, not access to the model for ordinary conversation.
What happens when I hit a free limit?
You don't hit a wall on basic chat. You hit quota ceilings on the metered features — deep research, agent runs, Agent Swarm, Kimi Code. The app prompts you to upgrade for those rather than cutting off a conversation mid-stream.
Does Kimi show ads on the free plan?
No. The free tier is ad-free; Moonshot's model is subscription-based, so the free plan exists to convert users to paid tiers, not to serve ads.
Can I use Kimi's free output commercially?
Be careful here. Kimi's consumer terms point toward personal, non-commercial use by default. Read the current terms before publishing or building on the output.
One more option most "is it free" articles skip: Kimi K2.6 is open-weight under a Modified MIT license, so the model weights on Hugging Face are free to download and self-host. That's a different kind of "free" — more work, real hardware required (think multiple high-end GPUs), but full control over where your data lives. Irrelevant for most people, genuinely useful if data residency is your constraint.
The free plan at kimi.com is more useful than you'd expect. I kept the tab open that Tuesday and finished the PDF — no credit card, no message wall. For document work and drafting, that's the whole story. The paywall only starts mattering once you want the autonomous, agentic side of the product.
