Local Model Deployment

Local model deployment breaks the dependency on cloud AI APIs. Instead of routing user queries to OpenAI or Anthropic, your applications call a model running on your own servers, within your own network perimeter. The model sees your data; no third party does. This architecture is non-negotiable for defense, intelligence, healthcare, and financial organizations with strict data handling requirements — and increasingly attractive to any enterprise that wants to eliminate per-token costs at scale.

The practical stack for local deployment has three layers. The **model layer** is the open-weight model itself (Llama, Mistral, Phi, Gemma), quantized to fit available GPU or CPU memory. The **inference server layer** runs the model and exposes an API — tools like Ollama simplify developer setup, while vLLM and llama.cpp power production-grade deployments with optimized throughput. The **application layer** connects to this local endpoint exactly as it would to a cloud API, often via an OpenAI-compatible interface that requires minimal code changes.

Hardware is the key variable. A 7B-parameter quantized model can run on a modern developer MacBook; a 70B model requires a server-grade GPU (A100, H100) or a multi-GPU cluster for production latency. Enterprises should right-size deployment based on model capability requirements, concurrent user load, and budget — recognizing that the economics shift strongly in favor of local deployment once query volume passes a threshold, and that hardware costs continue to decline.
