Self-hosted LLM
The practice of deploying and running large language models on an organization's own or leased GPU servers as an alternative to calling third-party API services. The core trade-off involves fixed infrastructure and operational costs versus variable pay-per-use API costs, along with considerations of data privacy and model control.
Timeline (last 90 days)
Self-hosting means the team bears 7×24 operational responsibility, becoming its own SRE, while the availability of API services is guaranteed by the vendor.
The true cost of self-hosting an LLM includes not only GPU rental fees but also idle time and engineering hours.
API bills are explicit costs, while the costs of self-hosting are implicit and dispersed, making a simple comparison of monthly API fees versus monthly GPU rental a dangerous oversimplification.
Hidden costs in self-hosted TCO that are easily overlooked include networking and storage costs, compliance and security investment, and experimentation and iteration costs, which when included significantly raise the break-even point.
Common reasons teams switch back from self-hosting to APIs include operational burden exceeding capacity, actual cost savings falling short of expectations, and model quality or iteration speed failing to keep pace with API vendors.
The cost advantage of self-hosting only holds when call volume is large, traffic patterns are stable and predictable, and GPU utilization can be maintained at a high level.
