Frequently Asked Questions

How much VRAM does Llama 3.1 70B LatamGPT SFT 1.0 need?

Llama 3.1 70B LatamGPT SFT 1.0 requires 43.3 GB of VRAM at Q4_K_M, or 142.1 GB at BF16. Full 4K context adds up to 0.7 GB (44.0 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 70.6B × 4.8 bits ÷ 8 = 42.3 GB

KV Cache + Overhead ≈ 1 GB (at 2K context + ~0.3 GB framework)

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.

KV Cache + Overhead ≈ 1.7 GB (at full 4K context)

Can I run Llama 3.1 70B LatamGPT SFT 1.0 on a Mac?

Yes — Mac Studio M1 Max (32 GB) and 84 other Macs can run Llama 3.1 70B LatamGPT SFT 1.0, the smallest at IQ2_M. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 43.3 GB of usable unified memory (RAM minus macOS overhead), from Mac Studio M5 Max (48 GB).

Can I run Llama 3.1 70B LatamGPT SFT 1.0 locally?

Yes — Llama 3.1 70B LatamGPT SFT 1.0 can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Llama 3.1 70B LatamGPT SFT 1.0?

At Q4_K_M, Llama 3.1 70B LatamGPT SFT 1.0 can reach ~111 tok/s on AMD Instinct MI350X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = (bandwidth GB/s ÷ model GB) × efficiency

Example: NVIDIA B200 → 8000 ÷ 43.3 × 0.65 = ~120 tok/s
