ERNIE-4.5-VL-424B-A47B-PT: hardware requirements
ERNIE-4.5-VL-424B-A47B-PT needs about 260 GB of memory at Q4 quantization — a 256 GB download plus room for context and overhead. That is beyond consumer hardware; use it through an API instead.
This is a mixture-of-experts model. Only a fraction of its 424B parameters are used for each token, so it runs faster than its size suggests — but all of it still has to fit in memory. The speed is that of a small model; the memory requirement is that of a large one. More on this →

Download sizes by quantization
Lower quantization means a smaller file and less memory, at some cost to quality. Q4_K_M is the usual starting point. What is this?
| Quant | Download | RAM @ 4K | RAM @ 32K | Source |
|---|---|---|---|---|
| Q4_K_Mrecommended | 256 GB | 260 GB | 266 GB | estimated |
| Q5_K_M | 300 GB | 304 GB | 311 GB | estimated |
| Q6_K | 347 GB | 351 GB | 358 GB | estimated |
| Q8_0 | 450 GB | 454 GB | 460 GB | estimated |
| BF16 | 847 GB | 851 GB | 858 GB | estimated |
“Measured” sizes are read from published GGUF files. “Estimated” sizes are derived from the parameter count and are typically within a few percent. The RAM columns add the context cache and runtime overhead to the download size.
