Kimi K2.5
A trillion-parameter visual agentic model with a comparatively small active footprint and public weights and code.
Checked release: Kimi-K2.5
Sources checked 2026-09-19
- Kimi K2.5 release
- · Primary source
- Kimi K2.6 release noted by Moonshot AI
- · Primary source
K2.5 remains the reference checkpoint here; Moonshot AI’s cited documentation notes a later K2.6 release.
The profile describes this checkpoint, not every release carrying the family name. Developer documentation is not independent reproduction.
THE MODEL / THE TERMS
Know what you are picking up.
- Parameters
- 1T total / 32B active, plus a 400M vision encoder
- Architecture
- Multimodal mixture-of-experts transformer with MoonViT vision encoding.
- Modalities
- text · image · video
- Context
- 256K tokens
- Weights license
- Modified MIT License
- Commercial use
- Generally permitted, with an additional display requirement for products above the license’s stated revenue or user thresholds.
- Memory
- The full checkpoint is server-class; quantized serving still requires careful multi-device planning.
- Known quantizations
- Official/community NVFP4, MXFP4, FP8, GGUF, and MLX variants are listed on the Hub
