Here’s a back-of-the-envelope estimate for the total training compute (in FLOPs) for GPT-3, using standard scaling heuristics and reasonable assumptions.

Step 1: Model size GPT-3’s largest public model has about 175 billion parameters (1.75e11).

Step 2: Training tokens OpenAI reported training on roughly 300 billion tokens for GPT-3-scale models. We’ll use 3.0e11 tokens.

Step 3: FLOPs per parameter per token A common rule of thumb for dense Transformer training is that the total training FLOPs is on the order of: FLOPs ≈ 6 × N_params × N_tokens This comes from accounting for forward and backward passes over all layers, including attention and MLPs, with constant factors absorbed into the 6× heuristic. Some estimates range from ~3× to ~12× depending on architecture details and precision; 6× is a reasonable midpoint.

Step 4: Compute the total N_params = 1.75e11 N_tokens = 3.0e11 FLOPs ≈ 6 × 1.75e11 × 3.0e11 = 6 × 5.25e22 = 3.15e23 FLOPs

Step 5: Sensitivity/uncertainty

If the token count were lower (say 3e11 → 2e11), this would scale linearly.
If the constant factor were closer to 3× or 12×, the result would vary by about 2× either way.
Some additional overhead (optimizer states, data/activation precision, mixed-precision efficiency, embedding layers, and short sequences vs long) could shift the constant modestly but won’t change the order of magnitude.

Conclusion A reasonable estimate for total training compute for GPT-3 (175B) is on the order of 3e23 FLOPs, with a plausible range of roughly 1e23 to 6e23 FLOPs.

3-Minute Stand-Up Comedy Routine

(Walks on stage, looks around, shakes head.)
You ever wake up in the morning, stretch, take a deep breath... and immediately regret all your life choices?

I woke up today, my body made a noise I’ve never heard before. It wasn’t a crack, it wasn’t a pop… it was more like my bones whispered, “You did this.”

Aging is wild. When you’re a kid, you fall off a bike, scrape your knee, and just run it off. As an adult, I sleep slightly wrong, and now my neck is on strike for a week. Like, it doesn’t even negotiate. Just full-on protest mode.

And it’s not just the body. My patience has disappeared. I was in line at the grocery store, and the guy in front of me had, I kid you not, 19 coupons. That’s not a couponer; that’s a mathematician. He was doing long division at the register, carrying the one, solving for X… Sir, I am here for bread. I did not sign up for an SAT exam.

Speaking of the grocery store… why is it that no matter what I buy, the cashier always asks, "Do you need a bag?" Like, yes. I’m buying 17 things. You think I’m gonna carry them out like some kind of overachieving circus act? Balancing a watermelon on my shoulder, eggs under my chin?

And self-checkout? That’s just unpaid labor. I scanned three things, and the machine had the nerve to say, “Unexpected item in the bagging area.” First of all, you put the bag there. Second, don’t make me feel like I’m stealing when I clearly don’t have the coordination for crime.

Look, I know my limits. I’m not built for a life of crime. I can’t even jaywalk without looking both ways five times. Like, I’ll see an empty road and still be like, “Mmm… let me wait.” Meanwhile, some 80-year-old woman is just strolling past me like she owns the city. I saw a guy jaywalk in New York without even looking up from his phone. That’s next-level confidence. That’s a man who has made peace with whatever happens.

I respect it. I really do.

Anyway, thanks for listening to me complain. I hope all your bones stay silent tonight.

(Walks off stage.)
