This model card implements a finetune of Qwen/Qwen3-0.6B for the conversational infill task described in the ConvFill paper.

This model should be used respecting the original license of the base model, Qwen/Qwen3-0.6B. The dataset that was used to finetune this model can be found here.

Deploying responsive, multi-turn conversational voice agents with large language models poses a critical challenge: cloud-based foundation models utilize reasoning, information retrieval, and tool use for high-value tasks, but introduce latency that disrupts natural conversation. In contrast, small models can respond quickly but lack capabilities needed in real-world tasks. We propose conversational infill, a task where a small, local model generates prompt, contextually appropriate dialogue and seamlessly incorporates delayed, external knowledge produced in parallel by a foundation model backend. This finetune trains Qwen/Qwen3-0.6B to perform the conversational infill task.

This model is intended to be used with the infrastructure in the ConvFill repository.

This model is not explicitly tuned for guardrailed behavior. Please use with caution.

Use the code in the ConvFill repository to get started with this model.
