How to Save Money on GPU Hosting
- Use monthly plans for 24/7 workloads. Multiply the hourly price by 730 to get the monthly cost: a Community Cloud RTX 4090 ($0.34/hour) is about $250/month, a Secure Cloud one ($0.74/hour) about $540. A fixed-price dedicated server ($279–$409/month) includes the whole machine, storage and bandwidth.
- Use interruptible or spot instances for training with checkpoints.
- Quantize AI models. 4-bit quantization lets a 24 GB card run 27–32B LLMs, so you do not need an expensive 80 GB GPU.
- Stop idle machines and use serverless endpoints for spiky traffic.
