Memory needed by context length
| Context | KV cache (est.) | Total memory (Q4) |
|---|---|---|
| 4K tokens | ~1.8 GB | ~73.9 GB |
| 8K tokens | ~3.5 GB | ~75.6 GB |
| 32K tokens | ~14.1 GB | ~86.2 GB |
| 128K tokens | ~56.5 GB | ~128.6 GB |
The KV cache grows with context length β a model that fits at 4K can run out of memory at 32K. Estimates assume an FP16 cache with grouped-query attention; actual usage varies by runtime.
