LemonSlice Flash - LemonSlice

Overview

LemonSlice Flash is our fastest avatar model, optimized for latency-sensitive interactive applications:

Lowest time-to-first-byte (200+ ms faster per response than our standard model)
Same capabilities as our standard model — zero-shot from a single image, any character style, gestures, and emotion control
No per-avatar fine-tuning or training required

See our blog post for a quantitative latency analysis demonstrating Flash as the fastest among competing avatar providers.

Flash is an enterprise-only feature. Contact support@lemonslice.com to get access.

Usage

Set the optional model parameter to "flash" when starting a session.

avatar = lemonslice.AvatarSession(
    agent_image_url="...",
    model="flash",
)

const avatar = new lemonslice.AvatarSession({
  agentImageUrl: "...",
  extraPayload: { model: "flash" },
});

transport = LemonSliceTransport(
    ...
    session_request=LemonSliceNewSessionRequest(
        agent_image_url="...",
        model="flash",
    ),
)

We recommend testing your avatars with Flash before switching from the standard model in a production environment.
