Best local LLM for the RTX 3080 (10 GB & 12 GB)
Last updated 2026-05-26 · Page updated 2026-07-13
Top 7 open-source picks for the RTX 3080, ranked by benchmark performance and real-world fit. Updated monthly.
The RTX 3080 shipped in two desktop variants, and the difference matters more for LLMs than for games: the original card carries 10 GB of VRAM, the later refresh 12 GB. Memory, not compute, is what decides which model and quantization you can load — so this ranking targets the 10 GB card. If you own the 12 GB variant (or an RTX 3080 Ti, which also has 12 GB), head to the RTX 3080 12 GB ranking instead: the extra 2 GB is exactly what lets 14B-class models fit at Q4_K_M.
On 10 GB, the sweet spot is the 7–9B class: every pick below needs about 6 GB at Q4_K_M, which leaves real headroom for the KV cache or a higher-fidelity quantization. Larger 12–14B models can still run with partial CPU offload, but expect a steep slowdown once layers spill out of VRAM.
Qwen 2.5 VL 7B
A 7B vision-language model from Alibaba with state-of-the-art results in its class, scoring 95.7 on DocVQA. Handles hour-long video, bounding-box grounding, and multilingual OCR.
Qwen 2.5 Omni 7B
Alibaba's first true omni-modal open model — text, image, audio, and video in, with text and speech out. A research-grade preview rather than a production-ready release.
Qwen 3.5 9B
Alibaba's next-generation dense 9B model with a 262K native context window and an improved toggleable thinking mode. Apache 2.0 licensed.
Qwen 3 VL 8B
The dense 8B entry in Qwen 3 VL, offering strong OCR and document analysis with a remarkable 256k multimodal context for its size.
Apertus 8B
The compact Swiss AI release trained on the Alps supercomputer, covering 1000+ languages including Swiss German and Romansh. Apache 2.0.
InternVL 3.5 8B
OpenGVLab's 8B vision-language model leading MMMU among open models. Built at Shanghai AI Lab and released under Apache 2.0.
Granite 4.0 H-Tiny 7B-A1B
IBM's edge-class hybrid MoE with 7B total and only 1B active parameters — Apache 2.0 licensed and built for embedded and low-cost serving.
