Wan2.1 1.3B - Text to Video

Try Wan2.1 1.3B - Text to Video in the Workbench

Run this model interactively, tune parameters, and compare outputs.

Model ID: wan-ai-wan2-1-t2v-1-3b-diffusers Wan-AI/Wan2.1-T2V-1.3B-Diffusers is a text-to-video diffusion model. It excels in generating 480P videos from text prompts efficiently on consumer-grade GPUs, requiring only 8.19GB of VRAM, while maintaining competitive video quality. Some other noteworthy features of Wan-AI/Wan2.1-T2V-1.3B-Diffusers include multilingual support (English and Chinese), image-to-video conversion, aspect ratio control, visual text rendering inside videos, prompt enhancement, and the ability to add sound effects or background music to generated videos.

Metric	Value
Parameter Count	1.3 billion
Mixture of Experts	No
Context Length	Unknown
Multilingual	Yes
Quantized*	No

*Quantization is specific to the inference provider and the model may be offered with different quantization levels by other providers.

Use the Workbench as a request builder: configure parameters for this model in the UI, then open the API tab to copy the exact cURL or Python call.

Sync
Async
Async with SSE

This blocks until the video is ready (typically 5-15 minutes). Prefer Async or Async with SSE for anything beyond quick experimentation.See the video generation reference for more details.
