With 11 GB of VRAM (about 9.9 GB usable) and 484 GB/s of memory bandwidth, the GTX 1080 Ti runs 15 of 39 popular open models fully on the GPU at 8K context. The largest is Mistral Nemo 12B at Q4_K_M, at roughly 44 tokens per second.
Best picks for the GTX 1080 Ti
Every model on the GTX 1080 Ti
Results at 8K context, picking the highest quality quantization that fits. "Offload" means part of the model runs from system RAM (we assume 32 GB), which works but is much slower.

What this means in practice
The GTX 1080 Ti is comfortable with models up to about 12B to 14B parameters. gpt-oss 20B is the most useful step up beyond that: it needs about 14 GB, so part of it runs from system RAM, but as a mixture-of-experts model it stays reasonably quick at around 11 tokens per second. Models from Llama 3.3 70B upward need 48 GB or more and are out of reach. NVIDIA cards have the broadest support: Ollama, LM Studio and llama.cpp all use CUDA out of the box.
The next memory tier up is 12 GB: RTX 5070, RTX 4070 / 4070 Super, Arc B580.

Questions
What is the biggest model the GTX 1080 Ti can run?
At 8K context the largest model that fits entirely in its 11 GB of VRAM is Mistral Nemo 12B at Q4_K_M, at roughly 44 tokens per second.
Can the GTX 1080 Ti run 70B models like Llama 3.3 70B?
No. It needs about 48 GB at Q4, which is far beyond 11 GB even with system RAM offload.
What is the best model for coding on the GTX 1080 Ti?
Qwen3.5 9B at Q6_K fits fully and runs at about 41 tokens per second. Pair it with an editor extension like Continue pointed at Ollama.
