🤖 Open-source models commoditize the model layer and move to the edge
Friedberg's argument off Mosaic ML's MPT-7B: a competitive foundation model can now be trained on public data for ~$200k, open-source variants proliferate on Hugging Face and outpace the closed labs, and the models keep shrinking until they run on a phone or Apple silicon at the edge of the network. The model layer therefore has no durable moat and no auditable choke point — the winners are the open-weights distributor and the edge-inference silicon, not the closed-model owners. Chamath takes the other side: you still need a thousand-GPU cluster to compile a frontier model and open weights do not transfer to an orthogonal problem without retraining.
also touching these tickers, same direction: Meta becomes America's open-source AI champion 27 (META) · Apple: the AI dark horse via local models 23 (AAPL) · Independent frontier-model labs lose to hyperscaler capital 14 (META) · Apple relocates US-bound iPhone assembly to India on the stated 18-month timeline 8 (AAPL) · Meta's AI assistant takes ten points of search share from Google 7 (META)
⚖ Why this verdict
fully deterministic — evaluate.py replays this from daily closes; nothing below is editable or hand-set
- Window: 2023-05-19 → 2024-05-19 — first mention + 12-month horizon, then the window locks.
- The call: ▲ LONG META (primary play). META rose 92.3% over the window → direction-adjusted R = +92.3% (the call made money).
- Benchmark: holding SPY over the same window returned +28.3% → α = +92.3 − (+28.3) = +64.0% — 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 92.3, α 64.0)· 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, Jason, Sacks | proxy-sensitive: AAPL→PARTIAL (+9.0%)

| ▲ LONG | META | stock | PRIMARY | Llama is the open-weights leader — Jason calls it 'Facebook's open model, which is number one'; open-source commoditization of the model layer accrues to the company giving models away |
| ▲ LONG | AAPL | stock | adjacent | Jason names Apple silicon explicitly as where the shrunken models land — on-device inference |
| ▲ LONG | QCOM | stock | adjacent | edge-inference silicon outside Apple's walled garden if models move off the datacenter |
Mention log
“So let me just push back on that, because Mosaic ML published this model that is, let me, I can pull up the performance chart, or Nick, maybe you can just find it on their website real quick of the new model they published. Chamath, they trained this model on open source data that's publicly available, and they spent $200,000 on a cluster run to build this model, and look at how it performs compared to some of the top models that are closed source.”
“Many hands makes for light work. The open source models are going to fit on your phone or the latest, you know, Apple silicon. So I think the cat's out of the bag. I don't know how they pull it back in.”
“If they spent $400 million in the last couple of years, you could probably assume that doing the same training exercise could be done for five to $10 million 18 months from now to generate the same model.”
“if it's happening at the software layer already now, just like it did in Web2 software, and then we see certain elements of Web2 hardware been open sourced, I think it makes pretty logical sense that you can expect the same things to happen in the AI world.”
“Because one of the big targets here is going to be open source software. So if you are, for example, open AI, which is no longer open, it's closed source, the number one thing you want to do is pull up the ladder before open source software can get a lot of momentum.”
“I think foundational models will have no economic value. I think that they will be an incredibly powerful part of the substrate, and they will be broadly available and entirely free... But I think open source models will basically crush the value of models to zero economically, even though the utility will go to infinity, the economic value will go to zero.”
“Most of the tests show that OpenAI is still ahead of the open source models. I think even people in the open source movement will tell you that OpenAI is, call it six months ahead... Nonetheless, if OpenAI just maintains a little bit of a lead over open source, then it could... It could basically win the vast majority of the call it consumer search or consumer GPT market.”
“eventually everyone will find something that they don't want or that they're not expecting, and they're going to say, I don't want to use this product anymore. And so it is actually an opportunity for many models to proliferate, for open source to win.”
“Well, so what Zuck said on the last Meta call is the reason we open source everything is because we don't directly sell AI. We create products that AI makes better. So by open sourcing this, we allow the community to advance the ball and we get to reincorporate those changes. So it's a very smart strategy for companies that aren't directly selling the AI.”
“By the way, did you guys see there was a meta demo, which I thought was really cool, which was it was run on Lama 70B, but it was a real-time translation tool, where the person was speaking in Hokkien Chinese and the other person was speaking in English and they were able to understand each other.”
“I would take the top open source projects. I'd find those top contributors, take the top 20 or so open source projects and back them to the tune of significant money, 50 million, 100 million, whatever it takes”
“the incumbents who already have all the training data, they may have to pay a fine, there'll be some slap on the wrist, but now you've created a real moat and barrier to entry and so secretly they're going to love it. And it's going to be a big problem, I think, for the open source movement”
“which they had spent billions of dollars creating in a completely open source way. And the testing on Llama 3 is that it's comparable to GPT-4. And I think this is what Chamath means by scorched earth, is that we now have a free model that's as good as GPT-4.”
“by open sourcing these models, they limit competition because VCs are no longer going to plow half a billion dollars into a foundational model development company. So you limit the commercial interest and the commercial value of foundational models.”
“when Llama 3 got released, I think the big takeaway for a lot of people was, oh, wow, they've like caught up to GPT-4. I don't think it's equal in all dimensions, but it's like pretty close or pretty in the ballpark.”
“What we're trying to do is not make the sort of smartest set of weights that we can. What we're trying to make is like this useful intelligence layer for people to use. And a model is part of that. I think we will stay pretty far ahead of, I hope, we'll stay pretty far ahead of the rest of the world on that.”
“these models will roughly all be the same, but there's going to be a lot of scaffolding around these models that actually allow you to build these apps. So in many ways, that is like the open source movement. So even if the model itself is never open source, it doesn't much matter because you have to pay for the infrastructure.”
