Qwen3 235B A22B Instruct 2507 FP8 Throughput GPU requirements

What it takes to run Qwen3 235B A22B Instruct 2507 FP8 Throughput locally: memory by quantization, the smallest GPU that fits, and the managed alternative.

Qwen3 235B A22B Instruct 2507 FP8 Throughput 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.

How it works

1
Check the table
Qwen3 235B A22B Instruct 2507 FP8 Throughput at 8K context across FP16, 8-bit, and 4-bit, with the smallest single device that fits each.
2
Tune the calculator
Longer context grows the KV cache. The slider shows exactly how much memory that adds.
3
Decide how to run it
MoE weights must fit in memory in full, so serving this locally means a multi-GPU fleet, not one card.

Common questions

How much VRAM does Qwen3 235B A22B Instruct 2507 FP8 Throughput need?

At 8K context: roughly 521 GB at FP16, 260 GB at 8-bit, and 143 GB at 4-bit, including KV cache and runtime overhead. Longer context adds memory linearly.

Can a single GPU run Qwen3 235B A22B Instruct 2507 FP8 Throughput?

At 4-bit, yes: a B200 (192 GB) or larger handles it at 8K context. At FP16 you need multiple devices.

Why does Qwen3 235B A22B Instruct 2507 FP8 Throughput need so much memory as a MoE model?

Only some experts activate per token, which sets speed, but all 235 billion parameters must sit in memory. MoE trades memory for throughput.

What license is Qwen3 235B A22B Instruct 2507 FP8 Throughput under?

Apache 2.0. Permissive: run it, fine-tune it, and own the result.

Is there an alternative to buying GPUs for Qwen3 235B A22B Instruct 2507 FP8 Throughput?

Yes: managed inference. Allocate serves Qwen3 235B A22B Instruct 2507 FP8 Throughput token-metered from $0.2 per million input tokens at provider list price, plus the 7% transaction fee. Idle time costs nothing.
