The competition from the open models is so strong now that this seems to be the only way to keep both companies afloat, given their dire financials. OpenAI probably hoped that they can achieve market lead and then lower the training costs (and make inference cheap enough to eventually escape the red numbers), but the opposite is happening: The competition comes closer and closer, thus training has to be kept up with full force, thus the bleeding continues.
But if they can position themselves as too important/dangerous to be available for everyone (thus this incident report and the clever mentioning of GLM 5.2), they could get the military supplier treatment and would be protected from the market.
