eRacks Publishes a Private-AI Sizing Guide: 70B-Class Models Run On-Premise from $5,995

FREMONT, Calif. - July 3, 2026 - PRLog -- eRacks Open Source Systems today published "Private AI, Sized & Priced," a vendor-neutral buyer's guide for organizations that want to run large language models on their own hardware rather than through a cloud API, and announced that a 70-billion-parameter model now runs on-premise on its AILSA server starting at $5,995.

The guide answers the question eRacks hears most from AI buyers: how big a machine do I actually need? AI servers are priced largely by GPU memory (VRAM). The guide gives a model-size-to-VRAM table (a 70B model in 4-bit quantization needs roughly 42 GB, about 80 GB in 8-bit), and adds the part most buyers miss: system RAM should be 1.5 to 2 times the VRAM, and a multi-GPU server needs a server-class CPU for the PCIe lanes.

It also lays out the cost crossover where owning beats renting. A 30-person team paying $30 per user per month for a cloud AI service spends about $10,800 a year, every year, with all prompts transiting a third party's servers. An on-premise server covers the same everyday inference and pays for itself in under a year. For teams handling protected health information, attorney-client material, government data, or unpublished research, the calculus is simpler still: the data cannot leave their control, and a private server is the only option.

eRacks AI servers run entirely on open-source software, with Ubuntu Linux plus Ollama, Open WebUI, vLLM, and PyTorch pre-installed and tested, so staff reach the AI from a browser on day one, with no per-seat fees and no data leaving the building.

The guide is published at https://eracks.com/guides/private-ai-sizing/. eRacks has built custom open-source servers since 1999 and will size a private AI server to a customer's exact models and user count at no charge.
