Scripting

Unleash the power of AI-driven video interactions with the Tavus API. Go beyond traditional bots—create interactive video tutors, virtual tour guides, or digital spokespeople that engage your audience with realistic, human-like conversations. With Tavus, the possibilities are endless.

This guide will walk you through the steps to quickly test out the API and start a conversation.

Quick Start

You can integrate an OpenAI-compatible LLM to replace our existing options (`tavus-llama`, `tavus-gpt-4o`, `tavus-gpt-4o-mini`).

Custom LLM Onboarding

You can integrate a variety of third-party TTS providers (cartesia, elevenlabs, playht).

Custom TTS Onboarding

You can set up a custom S3 bucket, enable recordings in rooms, and get notified when recordings are ready to be shared.

Changelog

This endpoint creates a new Replica that can be used to generate personalized videos. 

The only required body parameter is `train_video_url`. This url must be a download link such as a presigned S3 url. Please ensure you pass in a video that meets the [requirements](/sections/troubleshooting/training-video-size) for training.

Replica training will fail without the following consent statement being present at the beginning of the video:
> I, [FULL NAME], am currently speaking and consent Tavus to create an AI clone of me by using the audio and video samples I provide. I understand that this AI clone can be used to create videos that look and sound like me.

Learn more about the consent statement [here](/sections/troubleshooting/consent-statement).

Learn more about training a personal Replica [here](/sections/replicas/personal-replicas).


Create Replica

This endpoint returns a single Replica by its unique identifier. 

Included in the response body is a `training_progress` string that represents the progress of the Replica training. If there are any errors during training, the `status` will be `error` and the `error_message` will be populated.


Get Replica

This endpoint returns a list of all replicas that have been created by the API Key in use. In the response, a root level `data` key will contain the list of Replicas.


List Replicas

This endpoint deletes a single Replica by its unique identifier. Once deleted, this Replica can not be used to generate videos.


Delete Replica

This endpoint renames a single Replica by its unique identifier. 


Rename Replica

This endpoint generates a new video using a Replica and either a script or an audio file. 

The only required body parameters are `replica_id` and either `script` or `audio_file`. 

The `replica_id` is a unique identifier for the Replica that will be used to generate the video. The `script` is the text that will be spoken by the Replica in the video. If you would like to generate a video using an audio file instead of a script, you can provide `audio_url` instead of `script`. Currently, only `.wav` files are supported for audio file input.

If a `background_url` is provided, Tavus will record a video of the website and use it as the background for the video. If a `background_source_url` is provided, where the URL points to a download link such as a presigned S3 URL, Tavus will use the video as the background for the video. If neither are provided, the video will consist of a full screen Replica.

To learn more about generating videos with Replicas, see [here](/sections/video-generation/overview).

To learn more about writing an effective script for your video, see [Scripting prompting](/sections/video-generation/scripting-prompting).


Generate Video

This endpoint returns a single video by its unique identifier. 

The response body will contain a `status` string that represents the status of the video. If the video is ready, the response body will also contain a `download_url`, `stream_url`, and `hosted_url` that can be used to download, stream, and view the video respectively.


Get Video

This endpoint returns a list of all videos that have been generated by the API Key in use. 


List Videos

This endpoint deletes a single video by its unique identifier.


Delete Video

This endpoint renames a single video by its unique identifier.


Rename Video

With the Tavus Conversational Video Interface (CVI) you are able to create a `conversation` with a replica in real time.

### Conversations
A `conversation` is a video call with a replica. 

After creating a `conversation`, a `conversation_url` will be returned in the response. The `conversation_url` can be used to join the conversation directly or can be embedded in a website. To embed the `conversation_url` in a website, you can find [instructions here](https://www.daily.co/products/prebuilt-video-call-app/quickstart/).

Once a conversation is created, the replica will automatically join the call and will start participating.

By providing a `callback_url`, you can receive webhooks with updates regarding the conversation state.

[Learn about recording conversations here](/sections/conversational-video-interface/recording-rooms).


Create Conversation

This endpoint returns a single conversation by its unique identifier. 


Get Conversation

This endpoint returns a list of all conversations that have been generated by the API Key in use.


List Conversations

This endpoint ends a single conversation by its unique identifier.


End Conversation

This endpoint deletes a single conversation by its unique identifier.


Delete Conversation

This endpoint creates a new persona that can be used by replicas in conversations. 

With a persona, you are able to craft the personalities of your replica across conversations.

#### LLM
With the `llm` layer, you can leverage your own OpenAI compatible LLM or you can use one a Tavus provided model.
- **tavus-gpt-4o:** The smartest option for complex interactions.
- **tavus-gpt-4o-mini:** A hybrid model that balances performance and intelligence.
- **tavus-llama:** The **default** choice if no LLM layer is provided. This is the fastest model, offering the best user-to-user (U2U) experience. It’s on-premise, making it incredibly performant. 

[Get Started with Your Own LLM](/sections/conversational-video-interface/custom-llm-onboarding.mdx)

#### TTS
With Tavus' default TTS engine, you get the faster utterance-to-utterance speed, but you can always bring your own if you have voices already trained with:
- **Cartesia**
- **Elevenlabs**
- **Playht**
