By Kaleido Field Staff ยท July 18, 2026

Direct answer

Moonshot AI released Kimi K3 on July 17 as a 2.8-trillion-parameter, natively multimodal model with a one-million-token context window. The model is available through Kimi products and its API now; Moonshot says full weights will follow by July 27.

What Moonshot released

Kimi K3 uses a mixture-of-experts design with 2.8 trillion total parameters and activates 16 of 896 experts. Moonshot lists native image and video understanding, a one-million-token context window and long-horizon coding and research as core functions.

The model is available through Kimi, Kimi Work, Kimi Code and the Kimi API. Moonshot says full model weights will be released by July 27 and that a technical report with further architecture and training detail will follow.

The visual capability

Moonshot says K3 can inspect screenshots while editing code, reason about 3D scenes, work from images and video, and revise visual output during game, CAD and frontend tasks. It also reports multimodal benchmark results averaged across repeated runs.

Those results come from Moonshot's release evaluation. Native vision is a verified product claim, but the quality of perception, video editing and visual-agent work still needs independent testing across real tasks.

Limits in the release itself

Moonshot says K3 still trails Claude Fable 5 and GPT-5.6 Sol overall and warns that incomplete thinking history can destabilize output. It also flags excessive proactiveness when the model meets ambiguous instructions.

The company has published pricing and availability, but the weights and full technical report are not yet public. Claims about coding, chip design and research speed should remain attributed to Moonshot until artifacts and independent reproductions are available.
