Nex-N2 mini on the AMD Radeon RX 9070: VRAM by quantization

Assumes a 4K-token context with an f16 KV cache, on an estimated architecture — this model publishes no config we can read. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 16 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the AMD Radeon RX 9070: 8K 23.8 GB ✗ · 32K 29.4 GB ✗ · 128K 52 GB ✗. Past 8K it no longer fits 16 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? Nex-N2 mini on 24 GB of system RAM, CPU only: runs, but it is tight.
Why It Does Not Fit
Every Nex-N2 variant requires more VRAM than the AMD Radeon RX 9070 provides (16 GB).
