#102If inference is that cheap, why is not even one company profitable yet?
"Why would you reinvest profits back into a business that is extremely profitable, when you have the chance of pulling your money out?"

Because they're spending it all on training the next model.

The marginal cost is not the salient factor when the model has to be frequently retrained at great cost. Even if the marginal cost was driven to zero, would they profit?
But they don't have to be retained frequently at great cost. Right now they are retrained frequently because everyone is frequently coming out with new models and nobody wants to fall behind. But if investment for AI were to dry up everyone would stop throwing so much money at R&D, and if everyone else isn't investing in new models you don't have to either. The models are powerful as they are, most of the knowledge i…
This talent diffusion guarantees that OpenAI and Anthropic will have to keep sinking in ever more money to stay at the bleeding edge, or upstarts like DeepSeek and incumbents like Meta will simply outspend you/hire away all the Tier 1 talent to upstage you.
The only companies that'll reliably print money off AI are TSMC and NVIDIA because they'll get paid either way. They're selling shovels and even if the gold rush ends up being a bust, they'll still do very well.

#105The math on the input tokens is definitely wrong. It claims each instance (8 GPUs) can handle 1.44 million tokens/sec of input. Let's check that out. 1.44e6 tokens/sec * 37e9 bytes/token / 3.3e12 bytes/sec/GPU = ~16,000 GPUs And that's assuming a more likely 1 byte per parameter. So the article is only off by a factor of at least 1,000. I didn't check any of the rest of the math, but that probably has some impact on…

You are doing the calculation as they were output tokens on a single batch, it would not make sense even in the decode phase.

This doesn't quite sound right...isn't a token just a few characters?

IF.
If you do stagnate for years someone will eventually decide to invest and beat you. Intel has proven so.
Re: Are OpenAI and Anthropic losing money on inference?
#109This is a great article, but it doesn't appear to model H100 downtime in the $2/hr costs. It assumes that OpenAI and Anthropic can match demand for inference to their supply of H100s perfectly, 24/7, in all regions. Maybe you could argue that the idle H100s are being used for model training - but that's different to the article's argument that inference is economically sustainable in isolation.
There are also probably all kinds of enterprise deals that they are okay with high latency (> hours) that they do beyond the PAYG batch APIs
