Introducing Alibaba Wan 2.5 Fast: Revolutionary Text-to-Video AI with Native Audio Synchronization
The AI video generation landscape has just taken a giant leap forward. We’re thrilled to announce that Alibaba Wan 2.5 Fast Text-to-Video is now available on WaveSpeedAI, bringing you cutting-edge video creation with native audio synchronization—a capability that positions it as a direct competitor to Google’s Veo 3, but at a fraction of the cost.
What is Alibaba Wan 2.5 Fast?
Alibaba Wan 2.5 represents a breakthrough in generative AI, solving one of the technology’s most persistent challenges: creating audio that naturally matches visual content. Unlike traditional workflows that require separate audio recording and manual synchronization, Wan 2.5 generates fully synchronized videos with vocals, sound effects, and background music in a single pass.
Launched by Alibaba in September 2025, this natively multimodal model unifies text, image, video, and audio generation into one cohesive architecture. The result? Professional-quality videos with perfectly synced audio-visual content—no post-production alignment needed.
Key Features and Capabilities
One-Pass Audio-Video Synchronization
The headline capability that sets Wan 2.5 apart is its native audio-visual generation. Create videos with:
- Synchronized voiceovers with accurate lip-sync
- Automatic sound effects matched to on-screen action
- Background music aligned to scene changes and mood
- Natural dialogue generation that follows your prompt
Simply describe your scene in a well-structured prompt, and Wan 2.5 handles everything—visuals and audio together.
High-Quality Output Options
- Resolutions: 480p, 720p, and 1080p HD quality
- Frame rate: Smooth 24fps playback
- Duration: Up to 10 seconds of footage
- Aspect ratios: 6 different options for various platforms
Superior Multilingual Support
Wan 2.5 excels where many competitors struggle. The model reliably processes prompts in:
- English
- Chinese (including various dialects)
- Russian
- Spanish
- And other languages
Unlike some alternatives that display “unknown language” errors on mixed-language inputs, Wan 2.5 handles multilingual production seamlessly—perfect for global content creation.
Custom Audio Integration
Bring your own voice or music to the generation process:
- Supported formats: WAV, MP3
- Audio length: 3-30 seconds

Performance That Outpaces the Competition
Alibaba reports significant improvements over previous versions:
- 25% faster generation speed
- 30% better visual quality
- 40% improved semantic accuracy
- 35% enhanced motion fidelity
In testing, the model has produced “breathtaking” results—cinematic close-ups with realistic lighting, particle effects catching sunlight, and subtle facial expressions that feel genuinely human.
