| File | Quant | Size | Est. VRAM | Verdict on RTX 4090 · 24 GB |
|---|---|---|---|---|
| Spark-X2.5-4B-Q4_K_M.gguf | Q4_K_M | 2.6 GB | 4.0 GB | ✅ Runs comfortably |
| Spark-X2.5-4B-Q8_0.gguf | Q8_0 | 4.4 GB | 5.9 GB | ✅ Runs comfortably |
| Spark-X2.5-4B.gguf | GGUF | 8.2 GB | 10.2 GB | ✅ Runs comfortably |
Estimate: file size × 1.1 + KV cache at 8K + 0.5 GB overhead. Not a benchmark — how we calculate this.
