Estimated cost to self-host

Qwen3.8-2.4T-A95B needs about 1,324 GB of GPU memory at 4-bit with 32K context. The cheapest rental that fits is 8× B300 at about $45,331 a month.

That costs the same as roughly 17B tokens a month on Alibaba Cloud's API. Self-hosting is more expensive below that volume.

Estimates based on median on-demand rates for Nvidia GPUs. Memory is weights plus KV cache for one request, using FP8 KV cache where supported and FP16/BF16 otherwise. Break-even assumes a 5:1 input-to-output ratio. No guarantee of runtime support, usable performance, or that a matching quantized build exists. How we estimate costs.
