alt Hacker NewsThey do have a choice, as evidenced by all the times when the other option gets picked. The article you link tries to acknowledge ByteDance's Doubao and Alibaba's Qwen Max as exceptions, but forgets about Baidu's Ernie and iFlytek's Spark, which are also closed-weight. There's simply no consensus yet on which strategy is better, so different companies end up making different bets.
That’s because Baidu sells model access and iFlytek sells integrated products. Also both have released open models, just older ones. They just close their latest ones because they got the reputation they needed out of them and have transitioned to a product. Notice that both of these explain the motivation without resorting to unfalsifiable claims about "economic warfare".
