Frequently Asked Questions

How much VRAM do you need to run Qwen 3.8 Max (2.4T)?

With an estimated 2400B parameters, Qwen 3.8 Max (2.4T) needs roughly 2682 GB of VRAM in 8-bit (INT8), 1341 GB in 4-bit, and 5364 GB in FP16, including a 20% overhead for activations and KV cache.

Which GPUs can run Qwen 3.8 Max (2.4T)?

At 8-bit quantization, the most cost-effective option is 21x AMD Instinct MI250X (2688 GB combined VRAM, around $52.50/hour on-demand). Higher-end cards like the NVIDIA B200 or AMD MI355X reduce the GPU count needed.

Can Qwen 3.8 Max (2.4T) run on a single GPU?

No. Even in 4-bit, Qwen 3.8 Max (2.4T) exceeds the memory of any single current GPU, so a multi-GPU cluster is required.

How much does it cost to serve Qwen 3.8 Max (2.4T) in the cloud?

Renting 21x Instinct MI250X costs on the order of $52.50/hour, i.e. about $38,325/month running 24/7. Actual prices vary by provider and commitment; spot and reserved capacity can be significantly cheaper.
