## Choose when

### Choose UltraRAG if…

- Both UltraRAG and vllm serve LLMs with a focus on ease and speed of deployment; however, they offer different low-code frameworks.
- Tags unique to UltraRAG: easy, llm, flask, demo.
- Also covers LLM Frameworks.
- UltraRAG ships Docker support for self-hosted deployment.
- * When you need to build complex and innovative RAG pipelines quickly and with little code.

### Choose vllm if…

- Both UltraRAG and vllm serve LLMs with a focus on ease and speed of deployment; however, they offer different low-code frameworks.
- Tags unique to vllm: amd, llama, cuda, llm-serving.
- - When you need state-of-the-art throughput with efficient attention management using **PagedAttention**.

## When NOT to use UltraRAG

- * When a tool that requires extensive customization at the code level is necessary.
- * If your project does not benefit from pre-built integrations and instead needs unique, tailor-made solutions.

## When NOT to use vllm

- - For users who do not require or cannot support the hardware and software dependencies such as CUDA/HIP for optimal performance.
- - If your project focuses on model training rather than inference since vLLM's primary strength lies in serving and high-throughput applications.
- - When you need a tool that is highly portable to older or less common architectures, given its optimization for modern GPUs and specialized hardware might not be beneficial in those scenarios.
