AllocateQwen2 72B Instruct GPU requirements
What it takes to run Qwen2 72B Instruct locally: memory by quantization, the smallest GPU that fits, and the managed alternative.
Qwen2 72B Instruct serves up to 32,768 tokens of context; the KV cache grows linearly toward that ceiling, so the slider below shows exactly what longer context costs in memory.
Smallest single device that fits: L40S (48 GB)
How it works
Common questions
How much VRAM does Qwen2 72B Instruct need?
At 8K context: roughly 161 GB at FP16, 81 GB at 8-bit, and 44 GB at 4-bit, including KV cache and runtime overhead. Longer context adds memory linearly.
Can a single GPU run Qwen2 72B Instruct?
At 4-bit, yes: a L40S (48 GB) or larger handles it at 8K context. At FP16 you need a B200 (192 GB) or larger.
Does quantization hurt Qwen2 72B Instruct's quality?
Modern 4-bit quantization costs a small amount of quality for a 4x memory saving; 8-bit is near-lossless. Validate on your own tasks before production.
What license is Qwen2 72B Instruct under?
Qwen license. Check the license terms for your use case before deployment.
Is there an alternative to buying GPUs for Qwen2 72B Instruct?
Yes: managed inference. Allocate serves Qwen2 72B Instruct token-metered from $0.9 per million input tokens at provider list price, plus the 7% transaction fee. Idle time costs nothing.
