Can the AMD Instinct MI325X run GLM-4.5-Air?
Yes — here's how fast and up to what context, with real measured numbers.
GLM-4.5-Air on the AMD Instinct MI325X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 67k | 17.8-21.8 t/s | ~0.1-0.1 (slow) |
| Q8 | yes | 391k | 35.7-43.6 t/s | ~0.2-0.3 (slow) |
| Q4 | yes | 533k | 63.7-77.8 t/s | ~0.4-0.5 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to system RAM offload (depends on your system RAM) and speed drops to the "beyond" figure.
FAQ
Can the AMD Instinct MI325X run GLM-4.5-Air?▶
Yes. At Q4 it generates ~63.7-77.8 tok/s and fits up to 533k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.4-0.5 tok/s.
How much context fits?▶
At Q4, up to about 533k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
