Frequently asked questions
FAQ — Helios 14B
How much VRAM does Helios 14B need for video?
Helios 14B (14B parameters) requires approximately 46.3 GB of VRAM at FP16 precision for generating 25 frames at 768×512. Video generation typically requires more VRAM than image generation due to temporal attention layers.
Can I run Helios 14B on RTX 4090?
Helios 14B exceeds the RTX 4090's 24 GB VRAM at FP16 for video generation. Consider reducing resolution, frame count, or using a GPU with more VRAM.
How long does it take to generate a video with Helios 14B?
On a reference GPU (RTX 4090 24GB), Helios 14B generates a 25-frame video at 768×512 in approximately ~3m 10s at FP16 with 30 inference steps. Faster GPUs with higher memory bandwidth will reduce generation time.
What resolution and frame count does Helios 14B support?
Helios 14B supports up to 1280×720 resolution and 240 frames per generation at 24 FPS. Higher resolutions and frame counts require proportionally more VRAM.
