What we cover in this episode
- Zero Gravity's mission: breaking down barriers to elite careers for disadvantaged UK students
- The "knowing-doing gap"—why students struggle to act even when they know what to do
- Why their first prototype (a job suitability summary) didn't create the "wow moment" they expected
- The decision to use text chat over voice input and why guided prompts beat empty text boxes
- Context management techniques: removing stale tool calls, summarizing history, exposing tools conditionally
- Using different models for different tasks (GPT-5 Nano for structured outputs, lighter models for quick replies)
- Safeguarding architecture: moderation endpoints plus external verification with Unitary
- Building a failure taxonomy through internal red team/green team exercises
- What's next: long-term memory management for multi-year student journeys
