CogVideoX-5B | [text-to-video]
Tsinghua's CogVideoX-5B generates 10-second videos from text prompts at $0.20 per video. Trading inference speed for open-source flexibility, it provides full model weights and LoRA fine-tuning support for developers who need customizable video generation without vendor lock-in.
Use Cases: Marketing Content Creation | Product Demonstrations | Social Media Video Assets
Performance
CogVideoX-5B positions as an open-source alternative to proprietary video models, offering cost-effective generation while maintaining commercial-use licensing and full model access for custom training.
| Metric | Result | Context |
|---|---|---|
| Video Duration | 10 seconds | Continuous output with temporal coherence |
| Resolution | 720x480 (default) | Configurable via video_size parameter |
| Cost per Video | $0.20 | 5 generations per $1.00 on fal |
| Inference Steps | 1-50 (default: 50) | Higher steps improve quality at speed cost |
| Frame Rate | 4-32 fps (default: 16) | RIFE interpolation enabled by default |

Open-Source Architecture With Production Infrastructure
CogVideoX-5B runs diffusion transformers trained on large-scale video datasets, contrasting with closed API-only services by exposing full model weights and training pipelines for custom fine-tuning.
What this means for you:
-
LoRA fine-tuning support: Adapt the base model to specific visual styles or brand guidelines using your own video datasets without retraining from scratch
-
Negative prompt control: Explicitly exclude unwanted elements like blur, distortion, or static frames through the negative_prompt parameter for quality refinement
-
Deterministic generation: Lock outputs with seed values for reproducible results across pipeline runs and A/B testing scenarios
-
Guidance scale flexibility: Adjust CFG from 0-20 to balance prompt adherence against creative variation, with default 7 providing reliable starting point

How It Stacks Up
CogVideoX-5B Video-to-Video – CogVideoX-5B text-to-video generates from scratch using pure text prompts at $0.20 per video, while the video-to-video variant conditions on existing footage for style transfer and editing workflows. The video-to-video endpoint trades generative flexibility for temporal consistency when working with reference material.
MiniMax Video 01 Live – CogVideoX-5B prioritizes open-source flexibility and custom training capabilities through exposed model weights and LoRA support. MiniMax focuses on production-ready inference speed and higher resolution outputs for teams needing immediate deployment without fine-tuning infrastructure.
CogVideoX-5B Image-to-Video – CogVideoX-5B text-to-video creates videos from pure text descriptions, while the image-to-video endpoint animates static images for product showcases and visual storytelling. Both share the same cost structure at $0.20 per generation, with image-to-video providing tighter control over initial composition.
