📄 About Live Avatar
Live Avatar is an advanced AI model designed for real-time avatar generation, enabling users to create lifelike talking avatars from static images with seamless audio synchronization. Leveraging state-of-the-art video generation technology, Live Avatar transforms a reference image into a dynamic, expressive character that responds to audio input, capturing natural face-to-face conversation nuances and gestures.
This model stands out by streaming infinite-length videos with immediate visual feedback, making it ideal for interactive applications. Users simply provide an image as the avatar's base, upload a driving audio file (WAV or MP3), and describe the desired scene or character. The AI then animates the image to speak and gesture in sync with the audio, producing high-quality video clips tailored to the user’s specifications. Advanced configuration options, such as the number of clips, frames per clip, guidance scale, and acceleration level, allow granular control over video length, smoothness, and production speed.
Live Avatar’s robust pipeline ensures avatars mimic natural speech and gestures, enhancing realism and emotional expressiveness. The technology is powered by configurable acceleration, offering options from none to high, to match different performance needs. For consistent results, users can set a random seed, and the built-in safety checker ensures generated content meets platform standards.
Ideal use cases include content creation for social media, personalized video messaging, virtual assistants, online education, customer support bots, and interactive marketing. Brands, educators, and developers can leverage Live Avatar to humanize digital experiences, create engaging presentations, or automate video-based communication at scale. The model supports a wide range of creative and professional applications, from animating fictional characters to bringing brand mascots to life.
With its intuitive input system and flexible output settings, Live Avatar empowers users to create compelling video content without advanced technical skills. The platform operates on a pay-as-you-go credit system, making high-quality avatar generation accessible and scalable for projects of any size. Whether you’re a marketer, educator, or developer, Live Avatar streamlines the process of producing custom, AI-driven talking avatars for any scenario.

Frequently Asked Questions
Live Avatar accepts standard image formats (such as JPG, PNG) for the avatar reference and common audio formats like WAV or MP3. For best results, use clear images and high-quality audio recordings.
The AI analyzes the provided audio file and animates the avatar’s mouth and facial gestures in real time, creating natural speech synchronization and expressive movements that match the audio content.
Yes, you can specify the number of clips and frames per clip to determine the video’s length and smoothness. The acceleration setting also lets you adjust production speed as needed.
Live Avatar includes an integrated safety checker that helps ensure generated content adheres to community and platform guidelines, promoting responsible use.
Pricing varies by model and is based on a pay-as-you-go credit system. You only pay for the resources you use, making it flexible for different project sizes.
Credit consumption depends on video length and quality settings. Each clip (approximately 3 seconds) consumes credits based on frames_per_clip and acceleration settings. A 10-clip video at 48 frames per clip with no acceleration typically uses more credits than the same video with high acceleration enabled. The exact cost appears in your JAI Portal dashboard before generation starts. For budget-conscious projects, start with fewer clips and moderate frame counts, then scale up once you've validated the output quality. Batch processing multiple avatars with similar settings can help you estimate costs accurately for larger campaigns.
Yes, all paid outputs from Live Avatar on JAI Portal include commercial-use rights. You can integrate generated avatar videos into marketing campaigns, product demos, customer service applications, educational content, or any revenue-generating project without additional licensing fees. This makes Live Avatar suitable for businesses creating branded video content, agencies producing client deliverables, or SaaS platforms embedding avatar features. Always ensure your input images and audio comply with applicable rights and permissions—JAI Portal grants commercial rights to the AI-generated output, but you remain responsible for source material licensing.
Live Avatar synchronizes facial animations to any audio input regardless of language. The model analyzes phonetic patterns and speech rhythms rather than understanding language content, so it works equally well with English, Spanish, Mandarin, Arabic, or any other spoken language. However, the prompt field for scene descriptions currently processes English most effectively. For multilingual projects, provide your audio in the target language and write prompts in clear English to describe expressions and gestures. This approach ensures accurate lip sync across global markets while maintaining consistent animation quality.
Live Avatar generates video in clips of approximately 3 seconds each, determined by the num_clips parameter. For longer videos, increase num_clips up to the maximum of 100, which produces roughly 5 minutes of content in a single generation. If you need videos longer than this limit, generate multiple batches and concatenate them using standard video editing software. The seed parameter helps maintain visual consistency across separate generations when you need to extend a video beyond the single-batch limit. For truly infinite-length streaming applications, consider integrating Live Avatar via API for continuous real-time generation.
Live Avatar outputs video at a resolution optimized for the input image dimensions and selected quality settings. The model maintains aspect ratio from your source image while ensuring facial features remain clear and detailed. Output format is typically MP4, widely compatible with social media platforms, video players, and editing software. For specific resolution requirements, start with a source image at your target dimensions—the model preserves input resolution during animation. If you need higher resolution output, upscale your reference image before processing, or use post-processing tools to enhance the final video resolution while maintaining Live Avatar's natural animation quality.
⚖️ How Live Avatar Compares
Live Avatar distinguishes itself through real-time streaming capabilities and infinite-length video generation, making it ideal for interactive applications where immediate visual feedback matters.
