    Kimi K3 FAQ

    How much does Kimi K3 cost per million tokens?

    As of August 25, 2026, Kimi K3 Moonshot AI API pricing is $3.00 per million input tokens and $15.00 per million output tokens. Input tokens are the prompt you send; output tokens are the completion. Long answers therefore cost more than short ones even when the prompt stays the same.

    What is the blended API cost for Kimi K3?

    On this page the blended Kimi K3 API cost is $18.00 for 1 million input tokens plus 1 million output tokens. That 1:1 mix is the comparison scale used across the LLM pricing table. A 3:1 mix (three million input tokens per one million output tokens), which some calculators use, would be about $24.00.

    How much does a typical Kimi K3 request cost?

    A typical Kimi K3 API request with 100K input tokens and 20K output tokens costs about $0.60 at current rates as of August 25, 2026. Multiply that by daily or monthly volume to estimate spend. Caching, batch APIs, and volume discounts from Moonshot AI can bring the real invoice lower than the public list rate at https://platform.kimi.com/docs/pricing/chat.

    What is the context window for Kimi K3?

    Kimi K3 supports a 1M token context window and can generate up to 1M output tokens per request. The context window is the total prompt plus conversation history the model can see in one call. Larger windows cost more when you fill them, because every input token is billed per million tokens.

    Is Kimi K3 open source?

    Yes. Kimi K3 is an open-weight model by Moonshot AI. You can download the weights and self-host, or pay Moonshot AI's hosted API and skip GPU ops. Hosted API pricing on this page is the public per-million-token rate, not the electricity cost of running the weights yourself.

    What benchmarks does Kimi K3 perform well on?

    Kimi K3 currently reports Chatbot Arena 1489, HLE 56%, GPQA 93.5%. See the performance table for the full eval set. Use those scores with the token prices above when you are choosing between a cheaper LLM and a frontier model. GPQA, SWE-bench, and HLE are the evals people usually compare first.

    Is Kimi K3 good for coding?

    Kimi K3 scores 93.4% on SWE-bench Verified. Pair that score with Moonshot AI API pricing on this page: a slightly worse SWE-bench model can still win if it is much cheaper per million tokens. Open the SWE-bench or coding leaderboard from the sidebar for the full ranking, then jump into an LLM comparison against a coding specialist.

    How do I compare Kimi K3 with another LLM?

    Use the Compare picker on this page to start an LLM comparison. Search by model or provider, pick a second model, and AnotherWrapper opens a dedicated Kimi K3 vs page with per-million-token prices, blended 1M-in / 1M-out cost, context window, throughput, and benchmarks. You can also open any model from the sidebar, or go back to the LLM pricing table to sort the full index.

    What are the cheapest alternatives to Kimi K3?

    The cheapest LLM alternative depends on whether you optimize for blended token cost, coding evals, or context window. Start with the popular matchups on this page, then sort the LLM pricing table by blended cost to see which hosted APIs undercut Kimi K3. Open-weight models can be cheaper still if you self-host, but that is not the same as Moonshot AI API pricing on this page.

    How do I use Kimi K3 in my application?

    Kimi K3 is called through Moonshot AI's API with an API key. Bill against input and output tokens separately; cache or shorten prompts if spend is high. If you are shipping a full product, AnotherWrapper includes pre-built API routes and templates for Moonshot AI and 5+ other providers with auth, payments, and deployment already configured.

    How accurate is this Kimi K3 pricing data?

    This Kimi K3 page tracks the latest published Moonshot AI API pricing from Moonshot AI, quoted per million tokens. List rates can differ from invoices because of prompt caching, batch discounts, committed-use tiers, and private contracts. Official rate sheet: https://platform.kimi.com/docs/pricing/chat. Benchmark scores come from official publications and independent evals, not from a private lab run by AnotherWrapper.

    How fast is Kimi K3?

    Kimi K3 has a measured throughput of about 8.3 tokens per second (tok/s). Throughput is how fast completions stream once the model starts generating; time-to-first-token can still lag under load. Faster APIs matter when you are building chat or agents, even if the per-million-token price is the same.
