Cloze: An Open Research Platform for Studying Human-AI Conversations in Mental Health Contexts
Researchers have developed Cloze, an open-source platform designed to facilitate controlled studies of human-AI conversations within mental health contexts. Unlike consumer-grade LLMs such as ChatGPT, Claude, and Gemini, Cloze offers researchers enhanced experimental control, consistent data export, and integrated safety measures. The platform allows for configuration of AI models, instructions, conversation scheduling, and safety constraints, while meticulously logging all messages with full provenance, including model versions and prompt configurations. Cloze supports various models, including those from OpenAI, Anthropic, Google, and locally hosted options via Ollama, and can be deployed in the cloud or on-premises to ensure data privacy. AI
