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)
KV Cache + Overhead ≈ 1.7 GB (at full 4K context)
VRAM usage by quantization
Q4_K_M43.3 GBQ4_K_M + full context44.0 GB- Can NVIDIA GeForce RTX 5090 run Llama 3.1 70B LatamGPT SFT 1.0?
Yes, at Q2_K (31.0 GB) or lower. Higher quantizations like IQ3_M (32.7 GB) exceed the NVIDIA GeForce RTX 5090's 32 GB.
- What's the best quantization for Llama 3.1 70B LatamGPT SFT 1.0?
For Llama 3.1 70B LatamGPT SFT 1.0, Q4_K_M (43.3 GB) offers the best balance of quality and VRAM usage. Q5_K_S (49.5 GB) provides better quality if you have the VRAM. The smallest option is IQ2_M at 24.8 GB.
