An H100 today costs $2.95 an hour on vast.ai[1], which is already a good deal.
gpt-oss-120b on an H100 gives you ~200-250 tokens per second. I will be generous and say you can get a million tokens an hour out of it.
OpenCode Go (which I gladly pay for, because of this in part) is $10 a month, that's three hours of H100 use, and the models you have there are more expensive than gpt-oss-120b. Sure, they have "scale" (although that doesn't apply to AI inference, but whatever) and this and that, they're still pricing it 20-30x below their minimum threshold of capital expense.
Apples to apples, GLM 5.1 they sell it to you at $4.40 per million tokens, at ~50 tps in an H100 (being generous) it costs ~$16 to do a million tokens.
The math is simple and clear, they lose money.
