Not at Q4_K_M — that needs 16.8 GB and the NVIDIA GeForce RTX 4070 Ti Super has 16 GB. Drop to Q3_K_M and it fits in 14.4 GB, with up to 8K of context.

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 NVIDIA GeForce RTX 4070 Ti Super: 8K 19.3 GB ✗ · 32K 24.6 GB ✗ · 128K 45.5 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.
What to do next
Quantize to Q3_K_M. That is the cheapest fix — it costs some quality but no money.
