Frequently Asked Questions
How much VRAM does EXAONE 4.0 1.2B need?
EXAONE 4.0 1.2B requires 1.2 GB of VRAM at Q4_K_M, or 3.0 GB at BF16. Full 66K context adds up to 3.9 GB (5.1 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 1.3B × 4.8 bits ÷ 8 = 0.8 GB
KV Cache + Overhead ≈ 0.4 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 ≈ 4.3 GB (at full 66K context)
VRAM usage by quantization
What's the best quantization for EXAONE 4.0 1.2B?
For EXAONE 4.0 1.2B, Q4_K_M (1.2 GB) offers the best balance of quality and VRAM usage. Q5_K_M (1.3 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 1.0 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run EXAONE 4.0 1.2B on a Mac?
Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run EXAONE 4.0 1.2B. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 1.2 GB of usable unified memory (RAM minus macOS overhead).
Can I run EXAONE 4.0 1.2B locally?
Yes — EXAONE 4.0 1.2B can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is EXAONE 4.0 1.2B?
At Q4_K_M, EXAONE 4.0 1.2B can reach ~4034 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~551 tok/s. 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 ÷ 1.19 × 0.65 = ~4370 tok/s
Estimated speed at Q4_K_M (1.2 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of EXAONE 4.0 1.2B?
At Q4_K_M, the download is about 0.77 GB. The full-precision BF16 version is 2.56 GB. The smallest option (Q2_K) is 0.54 GB.
