Google introduced DialogLab a new open-source prototyping framework, uses a human-in-the-loop control strategy to achieve realistic human-AI group simulation, offering a necessary alternative to fully autonomous agents.

Evaluations with domain experts found that its "Human Control" mode (where you can edit, accept, or dismiss real-time AI suggestions) was preferred in realism, effectiveness, and engagement.

DialogLab transforms dialogue design from rigid scripts to spontaneous, adaptable group dynamics.
