Local LLM Infrastructure for the Solo Operator

The economics of local LLMs shifted in 2025. Models like GLM 5.1, Gemma 4, and Llama 3.3 run on consumer hardware with near-frontier capability. The tradeoffs extend beyond cost into control.

Local infrastructure delivers four advantages:

Privacy

Data never leaves your hardware

Latency

Zero network round-trips for inference

Reliability

No API outages, rate limits, or deprecation notices

Customization

Fine-tune, quantize, and modify without vendor permission

The setup takes effort. Maintenance is ongoing. But for operators building AI-native workflows, local models have become base infrastructure. A $2,000 Mac runs 30B-parameter models at production-quality output.
