I korthet

TorchServe is a framework for deploying PyTorch models as APIs. Package model + custom handlers, deploy to servers or Kubernetes. TorchServe handles batching, multi-GPU, model versioning, and A/B testing. Teams using TorchServe reduce time-to-production from weeks to days. Senior ML engineers comfortable with TorchServe earn 15-25% premium. Mastery takes 4-6 weeks.

Vad är Model Serving TorchServe

TorchServe is Facebook's framework for deploying PyTorch models as production APIs. You package your model (trained weights), write a handler (preprocessing and postprocessing code), and TorchServe exposes it via REST/gRPC endpoints. TorchServe handles operational concerns: batching (combine 32 requests into one forward pass), GPU management, model versioning, A/B testing, and metrics. This lets ML engineers focus on model quality, not infrastructure.

❓ Vanliga frågor

What does TorchServe do?
TorchServe packages PyTorch models into APIs. You provide model + custom handler (preprocessing, inference, postprocessing). TorchServe exposes REST and gRPC endpoints. Handles batching, GPU allocation, versioning, metrics.
How is TorchServe different from Flask + PyTorch?
Flask is general-purpose. You write all infrastructure code (batching, model loading, versioning). TorchServe handles it all. TorchServe = production-ready, Flask = DIY. Use TorchServe for critical models.
What's a handler in TorchServe?
Handler is a Python class that wraps your model. It implements initialize() (load model), preprocess() (convert input), inference() (run model), postprocess() (format output). TorchServe calls these methods in order.
Can I deploy multiple models in TorchServe?
Yes. Each model gets its own endpoint. Example: /predictions/bert, /predictions/yolo. TorchServe manages GPU memory, routing. Can have 10+ models on one server.
How do I handle model versioning and A/B testing?
TorchServe supports multiple versions of same model. Deploy new version alongside old. Route % of traffic to new version. Roll back instantly if bad.
What about monitoring and metrics?
TorchServe exposes Prometheus metrics: request count, latency, errors per model. Integrate with monitoring stack (Prometheus + Grafana). Alerts on anomalies.
