Frequently asked questions

How much VRAM does Llama 3.2 3B Instruct need?
About 3.7 GB at Q4_K_M with an 8K context, including the KV cache and runtime overhead. At Q8_0 it needs about 5.1 GB. A longer context adds more: about 3.5 GB of KV cache at 32K.
Can Llama 3.2 3B Instruct run on a Mac?
Yes on a Mac whose GPU can use at least 3.6 GB, e.g. M3 24 GB. macOS lets the GPU use about two thirds to three quarters of unified memory by default.
How fast is Llama 3.2 3B Instruct?
On a RTX 4090, we estimate 205–327 tok/s at Q4_K_M. This is an estimate from memory bandwidth (confidence low) until benchmarks are imported.
