A team of using TARX software pays $0/mo versus typical Claude cloud software at $280/mo. Attach a at $183/mo when the work needs more capacity.
T-4 shared-box starting point
1–25 people
People run TARX-OS on Apple silicon they already own. A Black Box is shared dedicated NVIDIA for the work those Macs cannot hold.
About 1–25 people can share one T-4 as extra NVIDIA. Indoor or vehicle.
Headcount is a deployment starting point, not a measured concurrent-user limit. Final size depends on active use, model mix, context length, latency, and site requirements.
Typical Claude mix is 80% $20 seats and 20% $200 seats. 4 × $20 + 1 × $200 = $280/mo. TARX software is free. T-4 is $6,600 ÷ 36 = $183/mo. People buy hardware for capacity, not a software seat. Place the box by the work: T-4 indoor or vehicle, T-7 field or robotics, T-70 1U rack.
Typical org mix is 80% $20 Claude Pro seats and 20% $200 Claude Max seats, counted as whole seats. Five people: 4 × $20 + 1 × $200 = $280/mo. All-Pro floor is 5 × $20 = $100/mo. TARX software is free. People buy hardware for capacity, not a software seat.
Lease or buy. Monthly is list ÷ 36. Third-party lease when we can place the paper. Terms in Deployment Design. Purchase is always available.
Figures are potential spend shifted versus a typical Claude mix. Not guaranteed savings.
