Kimi K2.6 from Moonshot AI — modified MIT license requires prominent display of 'Kimi K2.6' in product UI for commercial use with 100M+ MAU or $20M+ MRR, attribution-with-scale-threshold pattern
Moonshot AI's Kimi K2.6 ships under modified MIT license — requires prominent display of 'Kimi K2.6' in product UI for commercial use at substantial scale (100M+ monthly active users OR $20M+ monthly revenue). The attribution-with-scale-threshold licensing pattern represents middle ground between pure-permissive MIT and restrictive copyleft.
The substantive piece is the attribution-with-scale-threshold licensing pattern. Pre-K2.6 open-weight licensing operated at extremes — pure permissive (MIT, Apache) or restrictive (research-only, non-commercial). Modified MIT with attribution requirement at scale thresholds (100M+ MAU OR $20M+ MRR) provides middle-ground option that small-scale commercial users can adopt freely while large-scale users have visible attribution obligation.
The competitive read for the H2 2026 to 2027 open-weight licensing landscape is that licensing-pattern diversification continues. Pure MIT (GLM-5.2, others), modified MIT with attribution (K2.6), Llama Community License with use restrictions, research-only variants — vendors are differentiating on licensing terms beyond pure capability + economics dimensions. Procurement-evaluation should now include licensing-fit analysis alongside capability + cost evaluation.
