In this game, who wins - in the long term - is who has the best model: so far OpenAI is ahead, so in the long term this is what matters. However, for the same reason, if in the future open weight models will be very near the quality of frontier labs, Anthropic and OpenAI will be out of business very soon. The game they play only make sense if their SOTA models do things that other models can't do at a comparable leve…
You can theoretically do most things AWS does most of the time, yet people pay premium for it and keep paying for it, even though alternatives are cheaper, simpler and more performant.
I'd bet you that after 20 years OpenAI and Anthropic would still be around and kicking.
You might have a subpar product (for the price) but the reputation and history is what makes people open their wallets.
