Cosmos3-Edge: hardware requirements
Cosmos3-Edge needs about 3.3 GB of memory at Q4 quantization — a 2.3 GB download plus room for context and overhead. That fits a machine with 8GB RAM.

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 | 2.3 GB | 3.3 GB | 6.6 GB | estimated |
| Q5_K_M | 2.7 GB | 3.7 GB | 7.0 GB | estimated |
| Q6_K | 3.2 GB | 4.2 GB | 7.5 GB | estimated |
| Q8_0 | 4.1 GB | 5.1 GB | 8.4 GB | estimated |
| BF16 | 7.7 GB | 9.0 GB | 12 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.
