Moonshot AI releases Kimi K3 open weights with restrictive MaaS licensing requiring separate commercial agreements
“If the Licensee or any of its affiliates operates a Model as a Service business, and the aggregate revenue of the Licensee and its affiliates exceeds 20 million US dollars (or the equivalent in other currencies) in total over any consecutive 12 months, the Licensee must enter into a separate agreement with Moonshot AI before using the Software or its derivative works for any commercial purpose.”
Moonshot AI has released the weights for Kimi K3, a 2.8 trillion parameter model (1.56TB), with a license that goes beyond their prior K2 attribution requirement to mandate a separate commercial agreement for any MaaS operator exceeding $20M annual revenue. Notably, Moonshot avoids calling this 'open source,' consistently using 'open weight' instead — an increasingly important distinction as Chinese frontier labs release capable models under bespoke restrictive terms. The move signals a maturing strategy among open-weight labs to monetize large-scale commercial deployments while maintaining community adoption.
