CrePal Tests LTX-2 Model's VRAM Requirements Across GPUs

CrePal has published findings from practical tests conducted on its LTX-2 AI video generation model, focusing on Video RAM (VRAM) requirements. The tests, performed between January 10-13, 2026, assessed the model's performance on GPUs with 8GB, 12GB, and 24GB of VRAM, including popular models like the RTX 3060, RTX 4070, and RTX 4090.

The analysis categorizes VRAM needs into three tiers: minimum (8GB), comfortable (12GB), and creator sweet spot (24GB). With 8GB, users can run LTX-2 but are restricted to lower resolutions (512x512) and fewer frames, requiring careful setting adjustments. The 12GB tier offers a practical baseline, allowing for decent 512-640px clips at moderate frame counts without extensive tweaking. A "distilled" variant of LTX-2 was found to reduce VRAM usage by 30-40%, proving useful for users with limited memory.

For users equipped with 24GB of VRAM, the full LTX-2 model unlocked its optimal performance, enabling the generation of content at 720p and above, with longer clip durations (up to 32 frames). This level of performance is crucial for content creators aiming for professional-grade output with consistent quality. The study identified resolution, frame count, and batch size as the primary drivers of VRAM consumption.

CrePal advises users experiencing memory limitations to consider the distilled model or adjust resolution and frame rates. The insights aim to help users, particularly those with 12GB cards, efficiently utilize the LTX-2 model by understanding and managing its VRAM demands to avoid common issues like "CUDA out of memory" errors.
