What decision does this help answer?
At what monthly request volume might self-hosted inference become cheaper?
Calculation and methodology
Calculate managed spend from volume and API cost per accepted task. Calculate self-hosted spend from monthly GPUs, operations, maintenance and variable usage charges. If managed per-task cost exceeds self-hosted variable cost, solve for the break-even volume that covers fixed costs. All prices are typed by the visitor.
Limitations and responsible interpretation
This model omits hardware failures, utilization spikes, queueing, expertise requirements and differences in quality by default. Add those to the cost assumptions before a real decision. Break-even cost alone does not establish feasibility or reliability.
