The Kimi K3 model is an open-weights model reportedly sitting within the frontier band, with an alleged price of $3/$15 per million tokens. Its weights are scheduled to ship on July 27, though it appears to burn approximately 2x more tokens per task compared to GPT-5.6 Sol.
Open-weights models are directly challenging the pricing power of closed frontier labs, shifting the model layer towards commoditization and pressuring software margins.
