Self-hosted LLM vs API
The story so far
OpenRouter's report indicates that self-hosted LLMs are only cheaper than APIs when GPU load is sufficiently high. Taking the price as of October 8, 2026, for example, a 27B model requires a 6-12% load on rented RTX 3090 to balance with the API, while DeepSeek V4.1 Flash on four H200s has no balance point. GPU rentals are billed per hour, regardless of whether they are busy or not, while APIs are charged only based on the number of tokens used.
