Total Training Time Estimate | Generated by AI

Home 2025.11

Let’s compute your total training time clearly and compactly.


Given

We’ll estimate using the steady-state time, not the slow first iteration.


Step-by-step (simple)

Time per iteration: ≈ 3.9 seconds

Total time: 6000 × 3.9 s = 23,400 seconds

Convert:


Final estimate

≈ 6.5 hours of total training time

(on your RTX 4070 with this NanoGPT 125M config)

If your iteration time improves slightly as PyTorch compile warms up, final time may fall to 6.0 hr. If GPU is slightly busier or dataset slowdowns appear, expect 6.5–7 hr.

If you want, I can also compute ETA for other configs (256M, 350M, 1.3B, longer context, different GPU, etc.).
