AllocateQwen3 Next 80B A3b Instruct GPU requirements
What it takes to run Qwen3 Next 80B A3b Instruct locally: memory by quantization, the smallest GPU that fits, and the managed alternative.
Qwen3 Next 80B A3b Instruct serves up to 262,144 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: A100 (80 GB)
How it works
Common questions
How much VRAM does Qwen3 Next 80B A3b Instruct need?
At 8K context: roughly 179 GB at FP16, 89 GB at 8-bit, and 49 GB at 4-bit, including KV cache and runtime overhead. Longer context adds memory linearly.
Can a single GPU run Qwen3 Next 80B A3b Instruct?
At 4-bit, yes: a A100 (80 GB) or larger handles it at 8K context. At FP16 you need a B200 (192 GB) or larger.
Why does Qwen3 Next 80B A3b Instruct need so much memory as a MoE model?
Only some experts activate per token, which sets speed, but all 80 billion parameters must sit in memory. MoE trades memory for throughput.
What license is Qwen3 Next 80B A3b Instruct under?
Apache 2.0. Permissive: run it, fine-tune it, and own the result.
Is there an alternative to buying GPUs for Qwen3 Next 80B A3b Instruct?
Yes: managed inference. Allocate serves Qwen3 Next 80B A3b Instruct token-metered from $0.15 per million input tokens at provider list price, plus the 7% transaction fee. Idle time costs nothing.
