LemonSlice Flash - LemonSlice

Overview

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

Lowest time-to-first-byte (200-300ms 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 leading avatar providers.

Flash is available to users on Ultra and Enterprise tiers. See pricing.

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. Ensure there are no artifacts before pushing into production.
