Description
Kimi K3 is a language model from Moonshot AI. Webparam does not stock this model yet and can source it on request — tell us what you need it for and we will come back with availability and a price. Moonshot AI’s stated focus is long-context agentic intelligence (Kimi). The weights are not published, so it is API-only.
Capabilities
- Tool calling
- Calls functions you define and returns their arguments as structured data, the basis of agents.
- JSON mode
- Constrains the response to valid JSON matching a schema you supply.
- Streaming
- Emits tokens as they are generated, so answers appear progressively rather than all at once.
Strengths & weaknesses
Strengths
- 1.05M context
- Flagship-class quality
- Price quoted from the supplier's own rate card, not estimated
Weaknesses
- Priced with Western flagships rather than below them
- Not provisioned on this account yet — lead time applies
