Pros
- +Automatic failure handling and retry logic eliminates complex error recovery code
- +Mature, battle-tested technology originally developed at Uber with strong reliability track record
- +Comprehensive tooling ecosystem including CLI, Web UI, and multi-language SDK support
- +Exceptional serving throughput with PagedAttention memory optimization and continuous batching for production-scale LLM deployment
- +Comprehensive hardware support across NVIDIA, AMD, Intel platforms and specialized accelerators with flexible parallelism options
- +Seamless Hugging Face integration with OpenAI-compatible API server for easy model deployment and switching
Cons
- -Requires learning workflow-based programming paradigms which can have a steep learning curve
- -Additional infrastructure complexity requiring Temporal server deployment and maintenance
- -Overhead for simple applications that don't require durable execution guarantees
- -Requires significant GPU memory for optimal performance, limiting accessibility for resource-constrained environments
- -Complex setup and configuration for distributed inference across multiple GPUs or nodes
- -Primary focus on inference means limited support for training or fine-tuning workflows
Use Cases
- •Long-running business processes with multiple steps that need guaranteed completion
- •Microservice orchestration and coordination across distributed systems
- •Data processing pipelines requiring automatic retry and failure recovery mechanisms
- •Production API serving for applications requiring high-throughput LLM inference with multiple concurrent users
- •Research and experimentation with open-source LLMs requiring efficient model switching and testing
- •Enterprise deployment of private LLM services with OpenAI-compatible interfaces for existing applications
