Direction émotionnelle & mise en scène
Personnalité, script initial et voix orientent le personnage ; expressions et regard sont générés automatiquement.
Direction par instructionsParamètres et mécanisme
`personality`, `startScript`, `voice` et création de voix `from.prompt`.
Limite à garder visible
Pas de régie visuelle déterministe documentée par geste ou cadrage ; tester les réactions sur les tournants narratifs.
Personnalisation de l'avatar
RAG / Base de connaissances
Upload .txt files as knowledge base. Avatar queries them in real-time. Tool Calling enables external action triggers during conversation.
Comportement & personnalité
Personality via system prompt (overridable per session). Voice style presets (professional, authoritative, etc.).
Langage corporel & gestes
Fixed by reference image. Model generates natural body language but no granular API control.
Expressions faciales
GWM-1 generates natural micro-expressions and facial movements. Not manually scriptable.
Voix & clonage vocal
Voice presets (Clara, Vincent, etc.) with style variations. No custom voice cloning via Characters API at launch.
Fine-tuning du persona
System prompt overridable per session call. Tool Calling for external integrations. Starting script customisable.

Pertinence pour GamiWays
Score
7/10
Tool Calling is a unique differentiator for interactive educational scenarios. Zero-shot from image is excellent for rapid prototyping. 5-min session limit is a significant constraint for GamiWays's longer interaction scenarios.
