MoonshotMoonshot AILong-context text generation from Moonshot AI
Kimi K3 is a large language model developed by Moonshot AI, a Chinese AI company. It is designed for text generation tasks and features a context window of 1,048,576 tokens, allowing it to process and reason over very long documents or conversation histories in a single pass. The model supports a maximum response size of 131,072 tokens, making it suited for tasks that require extended output generation.
Kimi K3 was released in July 2026 and is available through MindStudio without requiring separate API key management. Its large context capacity makes it particularly well-suited for tasks such as long-document summarization, multi-turn conversation, extended code generation, and analysis of lengthy structured or unstructured text. Developers working with large corpora or complex, context-heavy workflows are the primary intended audience.
