HeyGen
Avatar V (April 2026)
. HeyGen's most advanced avatar model. Records identity from a 15-second consent clip and separates it from appearance, change outfits, backgrounds, and scenes without re-filming. Face Similarity benchmark score of 0.840, the highest published figure for any avatar AI. Long-form stability up to 60 minutes on Business plan with phoneme-level accuracy across 175+ languages.
Avatar IV
. The diffusion-inspired audio-to-expression engine launched May 2025. Analyzes vocal tone, rhythm, and emotion to generate photorealistic facial movements with hand gestures matched to the voice track. Supports front-facing, angled, and profile photo input. Best results under 7 minutes; expression loops become noticeable on longer content.
Photo Avatar
. Generates talking avatar videos from a single still photograph. Works on human headshots, cartoon characters, animals, and 3D model renders. Three steps: upload photo, add script or audio, generate. Useful for quick sales personalization where a full digital twin recording is impractical.
Video Translation
. Translates spoken video content into 175+ languages with AI lip-sync resynchronization and voice cloning that preserves the original speaker's vocal characteristics. Two modes: Speed Mode (rapid, sentence-level) and Precision Mode (video-aware, multi-speaker, better proper-noun handling). Precision Mode adds 30-to-60 minutes to processing time but produces markedly better brand-name sync.
LiveAvatar (Real-Time Streaming)
. WebRTC-based real-time streaming avatar available at liveavatar.com as a separate enterprise platform. Full Mode (HeyGen manages LLM, voice, and avatar) and Lite Mode (bring your own LLM, HeyGen provides the avatar layer). Sub-second latency. Used for customer support agents, sales demo presenters, and interactive onboarding assistants embedded in SaaS products.
Voice Cloning
. Clones a speaker's voice from a 90-second audio sample. Preserves pacing, breath placement, and tonal inflections across unlimited future renders. Used in the translation pipeline to maintain speaker identity across language versions and in personalized sales video to scale one recorded voice into thousands of individualized renders.
Video Agent
. Prompt-to-video pipeline launched September 2025. Describe the video in plain language and the agent drafts a script, selects an avatar, and assembles scenes. Video Agent API available via the API tier for programmatic workflows triggered by external systems.
SCORM Export
. Available on Business plan ($149/month), not gated to Enterprise. Exports as SCORM packages compatible with major LMS platforms including Workday Learning and Cornerstone. A structural price advantage over Synthesia, which requires a custom Enterprise contract for the same feature.
Brand Kit
. Available on Creator and above. Stores logos, color palettes, and font presets applied consistently across video outputs for brand-controlled production at scale.
CRM and Workflow Integrations
. HubSpot, Salesforce, Clay, Zapier, Make, and n8n integrations included on Business plan without a separate API subscription. The HeyGen + Clay combination is the documented canonical workflow for high-volume personalized sales video campaigns.
