vLLM provides an OpenAI-compatible online-serving server focused on high-throughput inference. Production sizing is more than fitting model weights into VRAM; KV cache, context, concurrency, tensor/data parallelism and API-server CPU load all matter.
Current vLLM documentation states `vllm serve` exposes OpenAI-compatible APIs including Completions and Chat. It also warns that `--api-key` only protects specific path prefixes and does not automatically secure every endpoint on the HTTP server, so production still needs network/proxy controls.
In vLLM V1, the API server handles input processing and streaming, the engine core manages scheduling/KV cache, and GPU workers execute model forward passes.
Tensor parallel splits a single model across GPUs. Data parallel replicates model instances across ranks to process independent request batches.
Official security guidance notes not every endpoint is protected by the built-in API key. Put vLLM behind private networking or a reverse proxy with TLS, rate limits and centralized authentication.
Replace the model name with your deployment model.

Do not choose GPUs only from model file size without benchmarking real traffic.
Yes. Its OpenAI-compatible server can work with many clients by changing the base URL.
No. Official docs warn it does not protect every endpoint; add proxy/firewall/auth controls.
When a model does not fit one GPU or model computation must be split across multiple GPUs.
Share model, precision/quantization, context, concurrency and target tokens/s; we can design GPU/VRAM and TP/DP.
