What hardware do I need for local LLM inference?

RTX 3070 or better with 12GB+ VRAM handles quantized 7-8B models. RTX 5070 Ti's 16GB sweet spot for 32K context.

Is llama.cpp fast enough for production?

Yes for low-concurrency subtasks — sub-second latency on consumer GPUs. Scale with multi-GPU or vLLM for high throughput.

Absolutely — zero data leaves your machine, dodging API compliance risks in healthcare, finance, legal.

Consumer GPUs like RTX 5070 Ti run production Llama 3.1 8B inference at near-zero marginal cost. 𝕏
Local setups excel for privacy, latency, and agent subtasks — not frontier reasoning. 𝕏
llama.cpp delivers OpenAI-compatible API with easy quantization for 16GB VRAM. 𝕏
