Full Summary
Kimi K3, developed by Moonshot AI, features an impressive 2.8 trillion parameters and is available for download at 1.56TB on Hugging Face. This release follows the modified MIT license introduced with Kimi K2, which mandated attribution for large commercial entities.
The K3 license has further tightened these requirements, necessitating a separate agreement for any Model as a Service business generating over 20 million US dollars in revenue within a year. Notably, Moonshot AI avoids labeling this as an 'open source' license, instead referring to it as 'open weight.'
OpenRouter is already providing access to K3 from multiple providers, maintaining competitive pricing for input and output usage.
