Can I Run VibeThinker 1.5B on NVIDIA GeForce RTX 5060 Ti 8GB?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 6 września 2026
Yes. VibeThinker 1.5B needs 2.4 GB at 8K context (0.9 GB weights + 1.5 GB KV cache/overhead) at Q4_K_M and the NVIDIA GeForce RTX 5060 Ti 8GB has 8 GB, leaving about 5.6 GB of headroom, at roughly 180 tok/s (estimated) with room for up to 64K of context.

VibeThinker 1.5B on the NVIDIA GeForce RTX 5060 Ti 8GB: VRAM by quantization

Assumes an 8K-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 8 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 5060 Ti 8GB: 8K 2.4 GB · 32K 4.4 GB · 128K 12.5 GB ✗. Past 128K it no longer fits 8 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Nothing to change — run it at Q4_K_M. If you want more capability, check whether the next size up also fits.
