Someone tried to make a clever comparison: "My car uses too much gas, so I'll start an oil drilling company" is supposedly like "API costs are too high, so let's build our own LLM." And honestly? The analogy is hilariously broken. Starting an oil company to save on gas is objectively insane—you'd need billions in capital, years of infrastructure, and you'd probably still pay more per gallon than just buying premium. But training your own LLM to avoid API fees? That's... also insane, but in a way that actually happens in tech. Companies really do look at their $50k/month OpenAI bill and think "we could train our own model for cheaper!" while conveniently ignoring the GPU costs, data engineering nightmares, and the fact that their model will probably think Paris is in Germany. The AI expert in the comments calling out the flawed logic is chef's kiss. Both scenarios are terrible ideas, but only one industry is delusional enough to actually try it. Guess which one.
