What is the best engine for production LLM serving?

vLLM is the top recommendation for production environments due to its high throughput and features like PagedAttention and continuous batching, specifically optimized for GPU clusters.

Can I run large language models on a CPU-only environment?

Yes, llama.cpp is the leading choice for CPU-only and edge deployment. By using GGUF quantization, you can run large models on standard system RAM with reasonable performance.

How do I choose the right quantization level for a model?

The Q4_K_M format is generally considered the 'sweet spot' for a balance between model quality and memory footprint, though Q5 or Q6 are preferred if you have sufficient RAM.

How can I fix Out of Memory (OOM) errors during inference?

Common solutions include reducing the context window size (n_ctx), utilizing a smaller quantization level, or reducing the number of layers offloaded to the GPU.

What are the benefits of using vLLM over standard transformers?

vLLM utilizes PagedAttention to manage KV cache memory more efficiently, allowing for significantly higher throughput and better handling of multiple concurrent requests.
