LLaVA 1.5 7B needs ~12.8 GB VRAM. GTX 1080 Ti 11GB has 11.0 GB. With Q2_K quantization, expect ~46 tok/s.
Operating mode
Interactive favors responsiveness, while light API and scale-out lean harder on serving readiness. The fit stays the same, but the recommendation lens changes.
Current mode

Offload
20%
It fits through host-memory offload, and offload is the main reason performance drops.
CPU or host-memory offload is active
About 10% of the working set spills out of accelerator memory, which usually hurts latency and sustained decode throughput.
Very little memory headroom
You can run the model, but there is not much room left for longer context, bigger batches, extra apps, or future model updates.
Older PCIe generation
PCIe 3.0 is workable, but it compounds the penalty when you offload heavily or try to scale across multiple cards.
Remove offload with more accelerator memory
Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.
Increase host RAM if you keep offloading
This setup may need roughly 0.4 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Yes, GTX 1080 Ti 11GB can run LLaVA 1.5 7B at Q2_K quantization (Very compromised (needs ~0.4 GB host RAM)). The recommended Q4_K_M requires 14.4 GB which exceeds available memory, but at Q2_K it needs only 12.8 GB. Expected decode speed: 46.2 tok/s.
LLaVA 1.5 7B (7B parameters) requires approximately 14.4 GB at Q4_K_M quantization. On GTX 1080 Ti 11GB, it fits at Q2_K using 12.8 GB.
The recommended quantization is Q4_K_M, but on GTX 1080 Ti 11GB the best fitting quantization is Q2_K, which uses 12.8 GB.
On GTX 1080 Ti 11GB, LLaVA 1.5 7B achieves approximately 46.2 tokens per second decode speed with a time-to-first-token of 4194ms using Q2_K quantization.
For coding workloads, LLaVA 1.5 7B on GTX 1080 Ti 11GB receives a F grade with 27.1 tok/s and 4K context.
On GTX 1080 Ti 11GB, LLaVA 1.5 7B can safely use up to 4K tokens of context at Q2_K quantization. The model's official context limit is 4K, but available memory constrains the safe maximum.
