Open-LLM-VTuber
A voice-first virtual character app with interruption-friendly conversation and Live2D avatars, connected to hosted or local LLMs.
What it is
Open-LLM-VTuber is a self-hosted app that lets a virtual character listen, speak, and respond in character. It connects speech recognition, an LLM, speech synthesis, and a Live2D avatar in one interaction flow, aimed at AI VTuber or desktop-character setups. It does not provide the language model itself: users still choose and configure a compatible hosted API or local model and speech components.
Core mechanisms and capabilities
It supports hands-free voice conversation and interruption, with replies tied to Live2D expressions and motion. Multiple hosted and local model backends are supported; the experience depends on the selected model, speech services, and avatar assets.
Editorial take
It merits inclusion as a highly followed, runnable AI VTuber project rather than a model or SDK. The maintainers are planning a v2.0 rewrite while focusing current work on v1 fixes. Licensing differs across components: the frontend has additional commercial-use conditions, and bundled Live2D samples have separate terms.
Who it suits
Best suited to users who want AI conversation presented through an on-screen or streaming character and can configure model, speech, and avatar components.
Deployment and technical requirements
The project is primarily self-hosted, with a server and web frontend as well as an Electron desktop client. Official quick-start and update instructions are available, but model, ASR/TTS engine, and operating-system choices affect dependencies. It is not a hosted service with a ready-to-use model.
Runtime requirements
An LLM, speech-recognition, and speech-synthesis backend must be configured. For microphone access from another device, the project notes that the browser needs a secure context such as HTTPS or localhost. Live2D assets may have separate licensing terms.
Users connect a supported LLM and configure speech recognition and synthesis, using local or hosted options. GPU needs, cost, and response quality depend on the chosen models and speech services; avatar assets also require separate terms checks.
Limitations and considerations
The README says v1 is being maintained while v2.0 is planned, so users should watch for migration-related configuration changes. GitHub identifies the repository license as Other: from v1.2.0 the frontend uses a custom license with additional conditions, while the backend remained MIT at that release. Commercial hosting, rebranding, and redistribution require checking the applicable terms.
