The flagship line

Two instruments lead
the house.

Fable5 and KIMI K3 are the names we put on the marquee. Every other model in the catalogue is tuned to serve beneath them.

Flagship Claude family

Fable5

The house flagship. Fable5 composes prose with a novelist's ear and reasons with an engineer's discipline — one instrument for narrative, code, and long-form thought.

Flagship Moonshot family

KIMI K3

Moonshot's frontier line. Long-context recall, vision, and step-by-step reasoning in a single instrument — built for documents that outlast the window.
