Deploying Llama 3 in production (EXPLAINED)
Self-hosting Llama 3 is a infrastructure-heavy question for ML platform and AI engineer roles at Meta-adjacent companies. Expect deep dives on quantization, vLLM, GPU sizing, and the TCO math that determines build vs buy decisions.
TL;DR — Quick Answer
GPU sizing, quantization (GPTQ/AWQ), inference server (vLLM/TGI), monitoring, safety guardrails, and cost vs cloud API trade-offs.
The Interview Question
What considerations are involved in deploying Llama 3 as a self-hosted production model?
Deep Explanation
Deployment stack: Model weights → quantization for memory efficiency → inference engine (vLLM for throughput, TGI for HuggingFace ecosystem) → load balancer → API gateway.
Consider: hardware (A100/H100 sizing), batching, KV cache optimization, fine-tuned vs base model, content filtering layer, and total cost of ownership vs OpenAI APIs.
