Deepseek seems to be drawing a distinction with licenses between R-1, v2, and v3. V2 and V3 clearly have the license mentioned (Deepseek License Agreement) distinguishing that code us under the MIT and the model is under the Deepseek License Agreement. R-1 seems to only reference MIT from what I see; this doesn’t mean it meets the Open Source AI definition - just pointing out the difference.
