About Streamer-Sales

Streamer-Sales is an open-source large language model application built to generate sales pitches for livestream and in-store product promotion. Given a product's features, it produces narration intended to highlight selling points and encourage purchase, aimed at e-commerce sellers and streamers who want AI-assisted sales copy and presentation.

The model is instruction fine-tuned from InternLM2 using xtuner, and the system integrates several components around it: LMDeploy for accelerated inference, retrieval-augmented generation so pitches can draw on up-to-date product manuals without retraining, an agent that can look up shipping information online, text-to-speech generation with emotional tone, automatic speech recognition for voice interaction, and generation of a digital-human presenter video so the pitch is not limited to text.

The stack uses a Vue, Pinia and Element Plus frontend with a FastAPI, Uvicorn and PostgreSQL backend exposing RESTful APIs with JWT authentication, and Docker Compose for one-command deployment. It is written in Python and released under the AGPL-3.0 license.
