On what basis are you are stating this? I'm asking because I have been involved in another project like these (15M budget) and the main issue was the lack of computing resources allocation, because no one thought about it (true story).
The application process IMHO is quite complex (thwy want compute estimations and CVs etc).However if you figure how ist works it is at least relatively easy to get batches of 100k GPU hours via EuroHPC. Currently few calls are open, but there is typically at least also national infrastructure. Again this is nothing compared to what OpenAI or Meta has access to.
I just got 25k node hours on Meluxina for a fine-tune project. My colleague got quite some GPU compute oh Germany's Tier3 NHR Clsuter (Horeka with >700 A100/H100 GPUs).
