Best local LLMs for 8GB
8GB is not a single ceiling. An 8GB Mac, an 8GB GPU and an 8GB Laptop each leave a different amount free for model weights, so the largest model you can run changes with the memory type, not just the number.

What 8GB actually gives you
Usable figures are sourced per device (tap a card for the full profile). Verdicts below use Q4_K_M, the community-default quant.
Runs comfortably on the most capable 8GB setup (Nvidia GeForce RTX 3060 Ti (8GB), ~7 GB usable) at ~5.7 GB. Check it against your exact device on its model page.

Each chip links to the full breakdown for that model on a real 8GB device. "Tight" means it fits but with little headroom, close other apps.
The ceiling, per memory type
Apple M1 (8GB) (~5.5 GB usable)
Runs up to Gemma 4 E2B (5.1B) comfortably at Q4_K_M. Larger models either sit tight or spill past the ~5.5 GB it can give a model.
Nvidia GeForce RTX 3060 Ti (8GB) (~7 GB usable)
Runs up to Gemma 3n E4B (8B) comfortably at Q4_K_M. Larger models either sit tight or spill past the ~7 GB it can give a model.
8GB RAM Laptop (CPU/iGPU only) (~5 GB usable)
Runs up to Nemotron 3 Nano 4B (4B) comfortably at Q4_K_M. Larger models either sit tight or spill past the ~5 GB it can give a model.
8GB phones & tablets
Phones report 8GB too, but iOS/Android reserve more and the runtimes differ. Their usable pool is smaller:
Too large for any 8GB device
FAQ
How much of 8GB can a model actually use?
It depends on the memory type. Apple unified memory: about 5.5 GB (Apple M1 (8GB)); GPU VRAM: about 7 GB (Nvidia GeForce RTX 3060 Ti (8GB)); System RAM (CPU only): about 5 GB (8GB RAM Laptop (CPU/iGPU only)). The rest is reserved for the OS, display and runtime overhead.
What is the best local LLM for 8GB?
Gemma 3n E4B (8B) is the strongest model that runs comfortably at Q4_K_M on the most capable 8GB setup (Nvidia GeForce RTX 3060 Ti (8GB), ~7 GB usable). On a tighter 8GB device the ceiling is lower, shown per row above.
Why does a 8GB GPU fit a bigger model than a 8GB Mac?
A discrete GPU gives almost all of its VRAM to the model (leave ~1 GB for the driver). Apple Silicon shares one unified pool with macOS, so roughly 66% is available to the GPU for weights. Same 8GB sticker, different usable budget, so the model ceiling differs.
