EXAONE 4.5 33B — Hardware Requirements & GPU Compatibility
VisionEXAONE 4.5 is LG AI Research's 33-billion-parameter vision-language model, the first open-weight vision-language release from the company. It adds a dedicated 1.29-billion-parameter vision encoder to the EXAONE 4.0 language model (31.7 billion parameters) and uses a hybrid attention design with sliding-window and global layers. The card says it outperforms state-of-the-art models of similar size in document understanding and Korean contextual reasoning, and it supports English, Korean, Spanish, German, Japanese and Vietnamese. Running it locally calls for a 24 GB or larger GPU once quantized, or a unified-memory machine. The model supports a 262,144 token context window. It is released under the EXAONE AI Model License Agreement 1.2 - NC, a non-commercial license, so commercial use is not permitted under its terms. It was published in April 2026 and builds on the earlier EXAONE 4.0 language models.

Which GPUs Can Run EXAONE 4.5 33B?
Q4_K_M · 21.4 GBEXAONE 4.5 33B (Q4_K_M) requires 21.4 GB of VRAM to load the model weights. For comfortable inference with headroom for KV cache and system overhead, 28+ GB is recommended. Using the full 262K context window can add up to 68.2 GB, bringing total usage to 89.6 GB. 7 GPUs can run it, including NVIDIA GeForce RTX 5090.
All compatible consumer-level GPUs are running near their VRAM limit. You may also want to consider professional GPUs (e.g., NVIDIA A100, H100) which offer significantly more VRAM. For more headroom and better throughput, consider a multi-GPU configuration with tensor parallelism (supported by tools like vLLM, llama.cpp, or text-generation-inference).

Frequently Asked Questions
- How much VRAM does EXAONE 4.5 33B need?
EXAONE 4.5 33B requires 21.4 GB of VRAM at Q4_K_M, or 69.5 GB at BF16. Full 262K context adds up to 68.2 GB (89.6 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 34.4B × 4.8 bits ÷ 8 = 20.6 GB
KV Cache + Overhead ≈ 0.8 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 69 GB (at full 262K context)
VRAM usage by quantization
Q4_K_M21.4 GBQ4_K_M + full context89.6 GB- Can NVIDIA GeForce RTX 4090 run EXAONE 4.5 33B?
Yes, at Q4_K_M (21.4 GB) or lower. Higher quantizations like Q5_K_S (24.4 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
- What's the best quantization for EXAONE 4.5 33B?
