No plan. No credit tiers.
Make one clip or a thousand. Add credits when you need them and spend them on any avatar, voice or video model, with no monthly plan to pick.
Hedra: Starts free, then monthly plans with a set number of credits, and generation speed depends on the plan.
The right model for every shot
InfiniteTalk for long talking and singing takes, Seedance 2.5 and LongCat Avatar for lifelike presenters, SCAIL-2 to make a character follow your own performance.
Hedra: Talking-character video is built on its own avatar models, such as Character 3.
Re-voice the video you already have
Not just still portraits: InfiniteTalk can lip-sync an existing clip to new audio, so you can dub or update a video without reshooting.
Hedra: Character 3 animates a start image with your audio.
One key for studio and API
Every avatar and voice model is one REST call away at the same per-run price, on the same balance as the studio.
Hedra: API access runs through a separate developer platform.
More than characters
Cinematic video, images, music, 3D and LLMs too, all on the same account and key.
Hedra: Its studio covers video, image and speech, with music listed as coming soon.

Frequently asked questions
Is WaveSpeedAI a good Hedra alternative?
Yes. Turn a portrait and an audio track into a lip-synced talking or singing video with InfiniteTalk, Seedance 2.5 or LongCat Avatar, create the voice with ElevenLabs, Gemini or Qwen3 TTS, and pay per run, with no monthly plan.
How do I make a talking video from a photo?
Open the avatar generator, upload a portrait and an audio track, and hit generate. Only have a script? Create the voice in the audio generator first, then use that file.
Can my character sing?
Yes. Upload a song instead of speech: InfiniteTalk and LongCat Avatar follow singing as well as talking, keeping the lips in time with the vocals.
Do I need a subscription?
Never. Add credits when you want and spend them on any model. No monthly fees, no commitments, nothing to cancel.
Can I try it for free?
Yes. Eligible new accounts get $1 in free credits, and you can sign up without a credit card. Some premium models may not be available with trial credits.
Is there an API?
Yes. Every avatar and voice model is one REST call away with a single key, at the same per-run price shown on its model page.
