🤖 Pre-training scaling laws still hold — Colossus and Grok 3 are the proof
Gavin Baker argues the 'we're hitting a wall' debate had no data because nobody had built a cluster past ~32,000 H100s. Elon's Memphis Colossus made 100,000+ hoppers coherent (going to 200k, then a million), so Grok 3 is the first real test of training scaling laws since GPT-4 and he expects it to be a significant advance in the state of the art. Friedberg adds new scaling axes — networks of models, test-time compute, context window — so capability keeps buying out of compute and the compute demand curve keeps compounding.
also touching these tickers, same direction: AI compute capex supercycle has 12-24 months of runway 87 (NVDA) · Nvidia + Hugging Face makes NVDA the open-source AI champion 58 (NVDA)

- Window: 2024-12-07 → 2025-12-07 — first mention + 12-month horizon, then the window locks.
- The call: ▲ LONG NVDA (primary play). NVDA rose 31.4% over the window → direction-adjusted R = +31.4% (the call made money).
- Benchmark: holding SPY over the same window returned +14.8% → α = +31.4 − (+14.8) = +16.7% — what this call made or lost against just owning the index. This is the number the verdict uses.
- Rule fired:
▶ HIT — R ≥ +10% AND α ≥ +5 ✓ (R 31.4, α 16.7)· PARTIAL — R ≥ +5% OR α ≥ 0· MISS — everything else
- Credit: supporters of a HIT earn 1.0 each, opposers the inverse — this feeds the scoreboard weights. supported: Chamath, Friedberg, Gavin Baker, Travis Kalanick | opposed: Jason, Keith Rabois

Mention log
“But you have not had a real test of scaling laws for training, arguably since GPT-4. And this will be the first test. And if scaling laws for training hold, Grok 3 should be a significant advance in the state of the art”
“I think it's a new kind of scaling access arguably in terms of the potential set of applications. So networks of models, think time, context window. There are multiple dimensions upon which these tools ultimately kind of resolve to better performance”
“I mean, basically what he proved was that there are still valuable gains in pre-training, and so the larger the cluster, the more value that there is... My first takeaway was I was sneakily surprised on the pre-training upside on having a larger cluster. So I think that that's very pro-NVIDIA actually, and it's actually also just really good in general for foundational model makers.”
“So why is this crazy? Well, he made this huge bet on this 100,000 GPU cluster. People thought, wow, that's a lot. Is it going to bear fruit? Then he said, no, actually, I'm scaling it up to 250,000. Then he said it's going to scale up to a million. And what these results show is a general computational approach that doesn't require as much human labeling, can actually get to the answer and better answers faster.”
“If you get, if you have an LM or foundational model of some kind that is the best in the world of the scientific method, game the F over. You basically, you just light up more GPUs and you just got like a thousand more PhD students working for you.”
“That's the global lesson, by the way. Chamath, you're totally right. Conceptual, the blog post is right. But that's only true when you have enough data and depending upon the use case, the level of data you need may not be possible for years, decades, and you may need to hack your way there through human interactions.”
“So this is incredible progress. And I think it's worth mentioning, this model was trained on Hopper. So this model is probably about as far as you can take the last generation of Nvidia GPUs. The next models we see, you know, Grok 5, you know, O5 from OpenAI, whatever they're going to call the next Gemini. They will be trained on Blackwell. And I think that will be a really big step function.”
“But this is the first time they have not released a model that was a decisively better. And the progress for Grok 4 was exceptional. Grok 5 is coming soon, you know, they have more.”
