Will It Fit? How to Calculate VRAM for Local LLMs (GGUF, EXL2) in 2026

Описание и применение

Калькулятор VRAM позволяет разработчикам быстро определить, поместится ли выбранная модель LLM на их GPU, избегая ошибок OOM.

Задача

Developers need to know if a local LLM will fit in their GPU VRAM before attempting inference, to avoid CUDA OOM errors.

Результат

The calculator eliminates guesswork, allowing developers to choose compatible models and configurations for their GPUs, reducing trial‑and‑error and preventing OOM crashes.

Рабочий процесс

• 1. Open the Local LLM VRAM Calculator on OmniTool Hub. 2. Enter the model size (e.g., 8B, 70B). 3. Select the quantization format (FP16, Q8, Q4, etc.). 4. Specify the target context length (e.g., 8k, 32k). 5. Review the calculated VRAM requirement. 6. Compare the result with your GPU’s available VRAM and adjust parameters if necessary.

Доказательства

Stop guessing and getting CUDA Out Of Memory (OOM) errors. We built a 100% client-side Local LLM VRAM Calculator on OmniTool Hub.
