There's no real incentive for the industry to coalesce around 2-3 models. I think it's very unlikely to happen.
It could be like the last SOTA lab to run out of money wins
Training is expensive. That seems like an important incentive.
I agree. Which is why I think the bubble is going to pop in the nearish term.
Nobody wants to admit that while partial to one company or another, brand and all that, I highly doubt that within 1-2 years we can tell the difference between model output for 90% of our tasks.
Except for the 'vibe' of some of the models with their writing or testing style I am not certain I could tell you which model is which unless asked.
Switching from model to model at the moment has been seamless without extensive 1 to 1 bench-marking but most of my tasks are never 1 to 1.
