Moonshot AI's Strongest Model Yet: Kimi K3.1 Frontend Identifier Leaked, Release Expected Soon
Summary
Several developers noticed a "kimi-k3-1" identifier appearing in the backend model registry of Moonshot AI's API platform, which passed interface probing and could be invoked. Later, Kimi's official open platform also showed a teaser for the K3.1 or K3 11111 model, supporting a 1M-token context window. Kimi K3.1 is expected to support up to a 1 million token context window and offer Low, High, and Max reasoning-intensity tiers, potentially introducing an Agent mode, Swarm multi-agent collaboration, and task modes such as search and batch processing. The open platform shows K3.1's API pricing is the same as the existing K3, though it may be a placeholder.
Bubble analysis
This is a model-release teaser, a product and technology story that sits several steps removed from the question of whether AI investment is a bubble. It discloses no funding, capex, or revenue figures and does not shift expectations about AI investment returns, so it is only weakly related.
