So... successfully reproduced in ~8.75 hours, taking about 18 kWh / $2.70

The first run actually failed at step 3000 or so, and I realized I had a bug in my attention / matmul kernels, but after fixing that and restarting it worked great

What was the final loss? Is this hardware available for rent somewhere?

Final loss from that fineweb-10B run (since then I'm up to ~100k toks/sec/GPU):

You can buy these GPUs on Amazon for under $1k. I heard the MI300X may be available in Azure now or at least very soon.
