Anam Cara-4 Director Notes vs Sume scene prompts and silence

Sume has no counterpart to Director Notes or an Expressivity dial in the docs cited here. What a Sume request can direct is the scene (a prompt or a photo), the pacing (silence beats and duration) and the quality tier.

Anam facts are from its Cara-4 post; Sume facts from Generate avatar video, read 2026-10-01.

What are Director Notes?

Anam says Director Notes, in beta with Cara-4, set the performance with a preset style (such as warm, supportive, angry or distressed) or a short custom prompt, and an Expressivity control sets how strongly the model follows it. During a session the LLM can add performance cues as it streams the spoken response. Cara-4 is available through the API with avatarModel: "cara-4".

What can I direct in a Sume avatar video?

scene takes { "type": "prompt", "prompt": "..." } or { "type": "photo", "image_url": "https://..." } for scene direction. Multi-scene video_inputs suit hooks, demos or silence beats. A voice.type: "silence" scene is a non-speaking beat and needs a duration. quality is standard, plus (default) or max; max is the highest tier with slower turnaround.

Does this change when the output is live or rendered?

Yes. Anam's controls act during a live session. Sume renders a finished clip from a script you wrote, so direction is settled before submit. For voice pace and mood, see avatar emotion and speaking speed.
