FAQ
Frequently asked questions
Hosting platforms are better for getting started, variable workloads, and teams without ML ops expertise. Self-hosting is better for consistent high-volume usage, maximum customisation, and data privacy requirements.
Costs vary widely. Serverless platforms charge per-second of GPU use. Dedicated endpoints cost $0.60-5+/hour depending on GPU type. High-throughput inference providers charge per-token at competitive rates.
NVIDIA A100 and H100 are most popular for large models. A10G offers good value for medium models. For smaller models, T4 GPUs provide affordable inference. Choice depends on model size and latency requirements.
Most platforms offer auto-scaling based on request volume. Configure minimum replicas for cold start avoidance and maximum replicas for cost control. Consider request queuing for handling traffic spikes.
Yes, all major platforms support custom model deployment. Upload your fine-tuned weights and deploy with the same infrastructure. Some platforms like Together AI offer integrated fine-tuning and hosting.
