Use Triton Inference Server when
One endpoint serving ONNX, TensorRT and Python models side by side.
Skip Triton Inference Server when
You serve one model family and want peak LLM throughput.
Turns weights into throughput. — that is what this layer of the stack is answerable for. See the full Inference & Serving section for the rest of the options.

- What are the alternatives to Triton Inference Server?
- The closest alternatives to Triton Inference Server are vLLM and Text Generation Inference.
Reading on inference
- Choosing an inference runtimeThe wrong runtime costs you throughput you never knew you were leaving on the table. The right one is usually decided by traffic shape, not model size.
- Context is a budget, not a containerThe instinct is to keep everything in case it is needed. The models are not filing systems, and past a certain length the middle of your context is doing nothing but costing money.
- Choosing a model is a routing problemThere is no best model. There is a best model for a task, at a quality bar, within a latency and cost budget — and that decision is a routing policy, not a benchmark.
