https://news.ycombinator.com/item?id=41833287 https://news.ycombinator.com/item?id=41833287 This says 506 tokens/second for Llama 405B on a machine with 8x H200s which you can rent for $4/GPU so probably $40/hour for a server with enough GPUs. And so it can do ~1.8M tokens per hour. OpenAI charges $10/1M output tokens for GPT4o. (input tokens and cached tokens are cheaper, but this is just ballpark estimates.) So if it were 405B it might cost $20/1M output tokens. Now, OpenAI is a little vague, but they have implied that GPT4o is actually only 60B-80B parameters. So they're probably selling it with a reasonable profit margin assuming it can do $5/1M output tokens at approximately 100B parameters. And even if they were selling it at cost, I wouldn't be worried because a couple years from now Nvidia will release H300s that are at least 30% more efficient and that will cause a profit margin to materialize without raising prices. So if I have a use case that works with today's models, I will be able to rent the same thing a year or two from now for roughly the same price.
