In this work, we present **AMD Hummingbird-XT**, an efficient **DiT-based** video generative model designed for high-quality video generation on client-grade GPUs with **5B parameters** .
 
Hummingbird-XT is trained based on Wan2.2-5B-TI2V using **DMD step distillation** with carefully designed **data curation**, enabling **3-step generation** while preserving high visual fidelity and motion quality. To reduce the computational overhead of high-resolution video decoding in 3D convolution–based VAE decoders, we introduce a **lightweight and efficient VAE decoder** by replacing part of the 3D convolutions with depthwise separable convolutions. Additionally, to further extend the length of generated videos, we introduce **Hummingbird-XTX**, an efficient **autoregressive model** for **long-video generation** based on Wan-2.1-1.3B, which is capable of generating long videos.
 
As a result, Hummingbird-XT achieves a **33×** speedup on Strix Halo iGPU and a **40×** speedup on  AMD Instinct™ MI325, and supports generating **121-frame** videos at **720×1280** resolution across both server-grade (AMD Instinct™ MI300 and AMD Instinct™ MI325) and client-grade (Strix Halo and Navi48) devices. Quantitative results on the VBench-T2V and VBench-I2V benchmarks show that Hummingbird-XT achieves competitive performance compared to the original **Wan2.2-5B-TI2V** model.
 
The Training and inference code is fully released on [Hummingbird-XT](https://github.com/AMD-AGI/HummingbirdXT), and the technical details is released on [Bridging the Last Mile: Deploying Hummingbird-XT for Efficient Video Generation on AMD Consumer-Grade Platforms](https://rocm.blogs.amd.com/artificial-intelligence/hummingbirdxt/README.html).

        Animated scene features a close-up of a short fluffy monster kneeling beside a melting red candle. The art style is 3D and realistic, with a focus on lighting and texture. The mood of the painting is one of wonder and curiosity, as the monster gazes at the flame with wide eyes and open mouth. Its pose and expression convey a sense of innocence and playfulness, as if it is exploring the world around it for the first time. The use of warm colors and dramatic lighting further enhances the cozy atmosphere of the image.

        A stylish woman walks down a Tokyo street filled with warm glowing neon and animated city signage. She wears a black leather jacket, a long red dress, and black boots, and carries a black purse. She wears sunglasses and red lipstick. She walks confidently and casually. The street is damp and reflective, creating a mirror effect of the colorful lights. Many pedestrians walk about.

        a back-view close-up focusing on the runner’s feet striking the track. Only subtle movement occurs—his steps land firmly, kicking a small amount of dust or rubber granules. The camera stays low and straight-on behind him, following smoothly with minimal shake. The sunlight bright with long shadows stretching forward.
