RTX 5090 inference access frustrates builders

The sharp takeaway is that RTX 5090 cloud economics look attractive only until availability, node quality, and failover become part of the bill.

• –Marketplace GPUs can win on hourly price, but production inference needs health checks, provider diversity, warm pools, and fallback SKUs
• –Managed providers reduce operational drag, but single-SKU dependence turns capacity gaps into user-facing outages
• –70B inference on consumer Blackwell cards is a cost play, not a reliability strategy by itself
• –The pragmatic setup is likely multi-provider routing across RTX 5090, RTX 4090, L40S, and H-series fallbacks rather than waiting for one perfect supplier
