## Frequently Asked Questions

### Is SGLang faster than vLLM for AI agents in 2026?
Yes, for multi-turn agent loops and structured JSON outputs, SGLang achieves up to 1.4x higher throughput than vLLM because RadixAttention automatically caches shared system-prompt and tool-history KV prefixes across requests.

### How much VRAM does Unsloth save during QLoRA fine-tuning?
Unsloth custom Triton kernels reduce VRAM consumption by 70% and double backpropagation speed with zero accuracy degradation, fitting 14B to 32B QLoRA runs on a single 24GB GPU.
