It was learned from multiple informed sources that after the Doubao large model was significantly reduced in price last year, the gross profit margin is still positive. Among them, ByteDance’s latest Doubao large model 1.5 has made further breakthroughs in inference cost optimization. Doubao-1.5-pro, which sells APIs on Volcano Engine, can still achieve a gross profit margin of 50%. In May last year, ByteDance officially released the Doubao large model. Among them, the Doubao general model pro-32k version has a model inference input price of only 0.8 yuan per million tokens, while the pricing of the same specification model on the market at that time was generally 120 yuan per million tokens, which is 150 times the price of the Doubao model.
