What was released
Kimi introduced Kimi K3 on July 16, 2026, and released the full weights on July 27. Its official help center describes a 2.8-trillion-parameter multimodal model with native visual understanding and up to a one-million-token context window. K3 is also available through Kimi's web and mobile apps, Work, Code, and API.
Why it stands out
- Releasing weights for a model at this scale expands research and self-hosting options.
- The design targets work that mixes large codebases, long documents, and visual input in one context.
- Kimi positions coding, long-running agents, and parallel Agent Swarm tasks as primary uses.
What to verify before deployment
A 2.8-trillion total parameter count does not mean convenient local inference. Teams still need to verify active parameters, quantization, GPU count and memory, and serving-framework support. Kimi's comparative benchmark claims should also be reproduced with the same harness and representative internal workloads.
