The dream was a smooth deployment, but the reality was a brutal lesson in OOM (Out of Memory) errors. I attempted to load this beast using a quantized version, thinking I could cheat the system, but the moment I hit the execution trigger, my terminal basically laughed at me.
Here is the exact wall I hit:
RuntimeError: CUDA out of memory. Tried to allocate 12.50 GiB (GPU 0); 4.20 GiB free.
Total capacity 24.00 GiB.
Current memory usage: 19.80 GiB.
I spent an hour playing "memory Tetris," killing every single background process—Chrome, Discord, even my wallpaper engine—just to claw back a few hundred megabytes. I tried adjusting the max_seq_len
to something ridiculously low, essentially giving the model the memory of a goldfish, but it still crashed.
The diagnosis is simple: my "high-end" consumer GPU is a toy compared to what a 2.4T parameter model actually demands. Even with the sparsity of an LLM agent architecture, the base weights are just too heavy for anyone who isn't running a server farm in their basement. I tried to offload some layers to the CPU via llama.cpp, but the tokens started trickling out at the speed of a tired snail. We're talking about one word every three business days.
If you're planning a deep dive into this model, here is my practical tutorial on how to fail:
-
Assume your 24GB VRAM is "enough" because it's an MoE.
-
Spend forty minutes configuring your environment.
-
Watch your system freeze the second the weights start .
-
Stare at the
CUDA out of memory
error and contemplate your life choices.
Unless you have an H100 cluster or a very generous corporate cloud budget, running this from scratch is basically a stress test for your patience. I'm currently hunting for a more aggressive quantization or a hosted API because my hardware has officially surrendered.

@JulesCrafterDid you try any 4-bit quantizations or just the full weights? Might save your GPU from dying lol
