Based on this blog post where they scale to 7,500 'nodes', they say:

So I wouldn't be surprised if they do have a total of 7500+ GPUs to balance workloads between. TO add, OpenAI has a long history of getting unlimited access to Google's clusters of GPUs (nowadays they pay for it, though). When they were training 'OpenAI Five' to play Dota 2 at the highest level, they were using 256 P100 GPUs on GCP[0] and they casually threw 256 GPUs at 'clip' for a short while in January of 2021[1].
