Break-even math: 4.8B tokens/month is the crossover for owning an 8-GPU H200 node
recentheartbroken · reddit · 2026-11-03
A practical break-even analysis for teams deciding between API tokens and self-hosting:
- Assumptions: 8-GPU H200 node at $329k amortized over 48 months ($6.9k/month), $800/month power, 25% overhead ($9.6k/month total) vs $2/million API tokens.
- Break-even: 4.8B tokens/month (160M/day).
- Under 1B: API clearly wins. 1B–5B: steady load favors owning, spiky load favors API. Above 5B steady: owning is hard to argue against.
- Non-cost factors that can override the math: data control, latency floors, fixed-cost budgeting.
- Author discloses they work at B3IQ, a GPU hosting company.
