Live Twitch delivery is not accepted yet

The native OBS 31+ caption path still needs target-machine validation. Lumi will not present a local simulated caption as live Twitch success.

First usable path

Setup progress

Complete one clear step at a time. Existing server administration remains in Lumi; streaming-computer controls remain in Companion.

  1. Download and pair CompanionCreate a short-lived, single-use package for the streaming computer.
  2. Install the OBS integration<%= devices.some((device) => device.metadata?.bridge_installed) ? 'A paired Companion has verified its managed OBS bridge installation.' : 'Companion owns installation and repair; the bridge has no separate settings.' %>
  3. Load and benchmark a modelSmall English is the recommended starting point.
  4. Select and test a microphone<%= devices.some((device) => device.metadata?.path_test_valid) ? 'The saved voice-free path check is still valid for the current configuration.' : 'Run the short voice-free path check once after setup or a relevant configuration change.' %>

Inference health

Speech recognition runs on the Lumi server, never on the streaming computer.

The low-latency package targets <%= runtimeManifest.artifacts.find((artifact) => artifact.backend === 'cuda')?.minimum_gpu || 'a supported NVIDIA GPU' %> and newer. Runtime changes activate immediately when no transcription session is active.

Shared GPU awareness

Lumi warns and benchmarks when Lumi AI already occupies GPU memory. It never unloads AI models automatically.

Paired devices

Active credentials are shown first. Switch to revoked history when needed; revoked records are permanently removed after 30 days.

Audio privacy

Raw audio is held only in bounded memory and is never written to disk by default. Diagnostic caption text is retained for seven days unless disabled.
