Every build
| Build | Quantization | Download | RAM needed |
|---|---|---|---|
| 70b-instruct-q4_K_MDefault | q4_K_M | 43 GB | 48 GB |
| 70b-instruct-q8_0 | q8_0 | 75 GB | 80 GB |
RAM figures are working-set recommendations: when GPU memory is short, the runtime spills to CPU and system memory instead of failing.
Install it
Pair a computer with idapt and install Llama 3.1 70B from the model page: the local engine bootstraps itself, pulls the build you pick, and streams progress. Or pull it directly:
ollama pull llama3.1:70b-instruct-q4_K_MFrequently asked
How much RAM do I need to run Llama 3.1 70B locally?
The smallest Llama 3.1 70B build runs with about 48 GB of system RAM; the largest needs 80 GB. RAM is the binding requirement: when GPU memory is short, the runtime spills to CPU and system memory instead of failing.
Which quantization of Llama 3.1 70B should I pick?
Start with the default 70b-instruct-q4_K_M build: a 43 GB download that wants about 48 GB of RAM. Smaller quantizations shrink the download and memory needs at some cost in output quality; larger ones do the reverse.
Do I need a GPU to run Llama 3.1 70B?
No. A GPU with enough VRAM makes generation faster, but Llama 3.1 70B runs on CPU and system RAM alone. Whether a build fits is decided by RAM; the GPU only changes speed.
How big is the Llama 3.1 70B download?
Between 43 GB and 75 GB, depending on the quantization you pick across 2 available builds.
Can idapt install Llama 3.1 70B for me?
Yes. Pair a computer with idapt and install Llama 3.1 70B from this page: the local engine bootstraps itself, pulls the build you pick (ollama pull llama3.1), and streams download progress. Local runs are not billed.
