LOCAL AI · ON-PREM

Run AI in your office, not on someone else’s meter.

Open models now handle coding help, document search, transcription and chat well on a single machine. We build it; you run it.

Private by default

Client files, code and financials never leave your premises. No third-party data terms to read.

Pay once

A one-time hardware cost instead of per-seat subscriptions and per-token cloud GPU bills that grow with use.

No limits, no outages

No rate limits or queueing. Works on your LAN even when the internet does not.

What runs on what

Pick a tier to see how fast it pays for itself.

Model sizes assume compressed (4-bit quantised) models with room for about an 8k-token context; real speeds vary with the model and settings. Prices are indicative and subject to change with market conditions. Final quote depends on configuration. Cloud comparison uses published on-demand rates from Indian GPU cloud providers, excluding GST (Nov 2026).

Will local AI pay for itself?

Picking a tier fills these in. Change any number to match your situation.

Cloud equivalent: a 16GB T4 GPU on an Indian cloud at about ₹30/hr, running 24×7 ≈ ₹21,900/month. Power and upkeep ≈ ₹2,500/month (estimate).

Every machine we ship is posted on Instagram — cable work, thermals, benchmarks and the brief behind it.

How we build

  1. 01ConsultYou tell us the software, workload and budget. We ask what slows you down today.
  2. 02Spec with reasonsA part list where every component has a one-line reason. No upsells you cannot justify.
  3. 03Build + stress test12+ hours of stress testing on CPU, GPU and memory. Thermals and clocks logged and shared with you.
  4. 04Deliver + supportOS and drivers set up, and every machine fully tested before delivery. Support after handover.
