OpenAI invested in non-open foundation models and DeepSeek came and (approximately) dethroned them. I don't agree with the conclusion of the article, but the statement "open-sourcing a model lets another company dethrone you" is also not great. I'd stand behind "in the world of AI in 2024/2025, regardless of whether the model is open or not, someone is likely to come and dethrone you in a snap".
> DeepSeek came and (approximately) dethroned them
The parenthetical should really be "(temporarily, approximately)". I wouldn't count OpenAI out until we see how o3 compares, assuming they actually make it available this week.
