A request typically passes through input validation, preprocessing, the model, and output processing. A text service may tokenize a prompt, run the model repeatedly to generate tokens, and assemble the response. Retrieval and external tools can add more stages around the model. Their time and errors count toward the user experience. Measure latency and throughput separately. Latency is how long one request takes; throughput is how many requests the system finishes over a period. Batching requests may improve throughput while increasing the wait for an individual request. Streaming can make an answer begin sooner without reducing the time required to finish it. Hardware memory must accommodate more than the model weights. Working buffers, concurrent requests, and cached representations also consume memory. Longer inputs and outputs can change the serving cost, so test the actual workload distribution rather than one short demonstration prompt. An inference deployment needs limits, timeouts, and a usable response when the model cannot answer. Keep a versioned evaluation set and compare outputs after changing precision, batching, model versions, or preprocessing. An optimization is useful only if it preserves the quality required by the task.
