Pro Tips for Maximum Value
Cost Optimization
- • Use spot instances for 50-70% savings on interruptible work
- • Stop instances when not in use (they still bill when idle!)
- • Use smaller GPUs for development, scale up for training
- • Batch similar workloads to maximize GPU utilization
Performance Optimization
- • Enable mixed precision (FP16) for 2x training speed
- • Use gradient checkpointing to fit larger models
- • Optimize batch size for your specific model
- • Profile your code to find bottlenecks
