HeyGen
Developer of avatar rendering and speech models, with identity-based image generation and a MiniMax-derived audiovisual model.
Current and legacy Avatar III are separate. Avatar IV/V, Video 1, Image 1, Voice 1/Turbo, Starfish and Panda are documented; Dolphin and Mockingbird are managed engines with unresolved base-model provenance. LiveAvatar and earlier versions remain under review. LiveAvatar real-time rendering and historical Instant Avatar 2.0 are now explicitly cataloged as managed components; unverified version equivalences and native checkpoint identities remain open.
Start with the job your model needs to do. Then narrow by capabilities, provider and price.
Compare every model with the same request.
Estimate = (input tokens × input price + output tokens × output price) / 1,000,000. Include conversation history in input and billed reasoning in output. Input-only decision models ignore the output setting; enter all billed input for one decision, including its question and criteria. Media, tools and discounts are separate.
