作者： Jakub Rusinowski · 最后更新： 2026年7月21日
Yes. Yi 1.5 34B Chat needs 23.6 GB at 8K context (20.8 GB weights + 2.8 GB KV cache/overhead) at Q4_K_M and the NVIDIA RTX 6000 Ada Generation has 48 GB, leaving about 24.4 GB of headroom, at roughly 37 tok/s (estimated) with room for up to 16K of context.

Assumes an 8K-token context with an f16 KV cache. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 48 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 RTX 6000 Ada Generation: 8K 23.6 GB · 31K 29.4 GB. Every window this model publishes still fits 48 GB.
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.
