vLLM PagedAttention Memory Layout: Why Our 70B Deployment Stopped OOMing

The 3 AM Page: 70B Model, 48GB VRAM, Instant OOM Last quarter we migrated our internal Q&A pipeline from Ollama to vLLM for higher concurrent request throughput. The first production deploy of a Llama-2-70B-GPTQ model on an A6000 (48GB) crashed within 90 seconds under moderate load—classic CUDA OOM…
