Rig Finder index / 32B / Coding assistant / Rhode Island
Best rig to run a 32B model for coding assistant in Rhode Island
For a 32B model at this workload, the RTX 3090 (used) pays off fastest — break-even ~10 months, keeping $3,140 over 3 years versus Claude Sonnet 4.6.
Same workload, same cloud, same electricity — we swap only the hardware and rank by real break-even. Rigs that can't run a 32B model are shown, never recommended. Compared against Claude Sonnet 4.6 ($3/M in, $15/M out); change the cloud in the lab.
