As of August 21, 2026, Kimi K2 0905 Moonshot AI API pricing is $0.60 per million input tokens and $2.50 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.

On this page the blended Kimi K2 0905 API cost is $3.10 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 $4.30.
A typical Kimi K2 0905 API request with 100K input tokens and 20K output tokens costs about $0.11 at current rates as of August 21, 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.
Kimi K2 0905 supports a 262K token context window and can generate up to 262K 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.
No. Kimi K2 0905 is a proprietary model by Moonshot AI. The only public way to call it is Moonshot AI's API, billed per million input and output tokens. There is no self-host option for the weights.

Kimi K2 0905 scores 94.5% on HumanEval. 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.
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 K2 0905 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.
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 K2 0905. 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.
