How It Works
UponAI has a hard-coded stop sequence in the LLM:NO_RESPONSE_NEEDED. When the LLM outputs this exact sequence, response generation stops immediately and the agent says nothing.
Setup
Add a prompt instruction telling the agent to output the stop sequence on hold requests:This feature does not apply to reasoning models (e.g., GPT-5, GPT-5.1), which do not support custom stop sequences. For those models, use prompt engineering instead:
When user says "hold on", simply do not respond.
