Overview

MoonshotAI: Kimi K3 is a large language model API from Moonshot AI, part of its Kimi K3 model family. With $3.00 per million input tokens and $15.00 per million output tokens, it is a premium-tier model where output volume is the main cost to watch. Output tokens cost about 5× as much as input, so prompt-heavy workloads run noticeably cheaper than generation-heavy ones. An exceptionally large 1.05M-token context window (≈1,573 pages of text) means entire repositories or document collections can be processed without chunking. Beyond plain text it also accepts Image input, so it can be applied to multimodal tasks rather than text alone. On Artificial Analysis's Intelligence Index it scores 57 (S grade), a useful proxy for its general reasoning strength relative to the other models tracked here. All prices on this page reflect OpenRouter's routed rates and are re-synced automatically every day; confirm against the provider's official pricing before committing to production.
