Profitable without Capex, i.e. gross margin. Inference is included in COGS. Capex (training) is not. That's reasonable.
1. ChatGPT's ~billion weekly active users aren't going to give a shit about some open source model, and neither would most of Anthropic's Enterprise cutomers.
2. Open AI and Anthropic are in a race between themselves, not open source model trainers. There's a reason those models are consistently several months behind and often perform much worse than benchmarks indicate. In the first place, they're only as close as they currently are from the distillation attacks on Anthropic and OpenAI. If they slowed down, they would slow down too.
2. "They're only as close..." is not natural law. You really think open weights couldn't catch up to a fixed target if Beijing makes it a priority? And what happens to their valuations if they abandon the goal of building AGI? There is no strategic alternative to constant training for these companies, which is why they're, uh, constantly training.
2. Nobody said anything about a fixed target. Not sure why you interpreted 'slow down' as 'freeze current models forever'.
>And what happens to their valuations if they abandon the goal of building AGI?
The capabilities these companies already have, combined with their growing userbases, revenue and distribution are plausibly enough to sustain trillion dollar businesses already. OpenAI is a company with a billion active users that has started running ads that reached ARR of $1 billion in the first 2 months and Anthropic is a company that hit $11B+ in revenue last quarter after a pretty massive jump.
Well, I'm not really talking about freezing models forever either, I'm saying that nonstop training is a necessary part of their business. I don't think slowing down is untenable, I just think it's silly not to expect & account for ongoing training costs. That's all my original comment meant.
I also don't understand why you think the open labs couldn't catch up to a given level of quality. If something's been done twice already, why can't a well funded team of experts somewhere else do it a third time? Sounds like wishful thinking.
Are you confident that a step change in open source is unlikely? The industry seems to disagree, considering billions are being spent on them and billions are being spent to stay ahead of them. Open step changes have happened before (eg R1, or heck, self-attention). By the way, AIs themselves are quite good at writing GPU kernels now.
How is this different from planes or cars? If Ford or Boeing zero line their R&D...well, we know what happens.
The concept this entire thread seems to need is the difference between fixed and variable costs.
lol
This is an open question!
In your car example the training is much like setting up the manufacturing line.
I think the issue here is that the capex depreciates super fast since the models obsolete really fast.
