Hedra

The pricing page says to start free but lists no free plan and no free credit amount; the cheapest card is Basic at $20 a month. Its FAQ adds that a cancelled account keeps limited watermarked generations, so a free tier of some size exists, but this profile cannot say how large it is. Treat free use as unconfirmed until you sign up and read your own credit balance.

Hedra sells two separate things. Studio is a subscription (Basic $20, Pro $50, Ultra $100, Teams $75 a month) with monthly credits that reset each cycle; credit packs do not expire. The API is a prepaid dollar balance with no subscription, billed per second or per token, and the billing docs state Studio credits cannot fund it. Studio credits are charged by generated length, but the pages we read give no credit rate per second, so the cost of a finished clip has to be read inside the app. A rough API figure: 60 seconds of avatar video at the ‘from’ rate of 2.5 cents a second is $1.50, and the real rate depends on the model.

The homepage now leads with model infrastructure (inference, training and a World Model Runtime), while the Studio page describes the creative product: an agent that plans and generates video, image and speech across third-party models such as Kling, Veo, Seedance and ElevenLabs, with shared Spaces, saved Elements and Skills. Older write-ups describe Hedra mainly as a talking-avatar app; the Character-3 avatar model is still listed in the API docs, but Studio is now framed as an agent workspace.

The Terms say Hedra claims no ownership of inputs or outputs, and that you grant Hedra a broad licence to use them to run the service. The Acceptable Use Policy is the stricter limit for avatar work: it forbids photos, audio or video of anyone other than yourself, and deepfakes that mislead without consent. That reads as a barrier to avatars of customers, staff or public figures, so check it before planning a presenter series.

1. Write down the clip length, the model you want and how many revisions you expect.
2. Sign up, note the credit balance shown, and generate one short clip of that model.
3. Divide the credits spent by the seconds produced and multiply by your monthly seconds.
4. Compare the result with the 2,000 credits in Basic and the 7,200 in Pro.

Accept if the cost per second is visible before generation and fits one tier. Reject if revisions use up a month of credits. No result is recorded here.
