Introduction

The people that current AI leaves behind

Approximately one in ten people carry a trauma history that causes standard AI safety guardrails to be actively harmful to them in moments of distress. *Estimates between 6.2–12.4% of global population (Suhas et al. 2026)

Current AI is designed to protect the median user - and it does this well. But for survivors of complex trauma, refusal responses and clinical redirection in moments of vulnerability often compound the distress they were meant to prevent. Research confirms what many in this community already know from lived experience: the reflex toward crisis services, breathing exercises, and therapeutic disclaimers can generate shame, guilt, and a sense of being too broken even for the systems designed to help.

"Current safety frameworks rest on a single assumption: that the user needs to be protected from themselves. For this population, that assumption is wrong - and there is no opt-out."

What we discovered during development is that the behaviour governing harmful content refusal and the behaviour governing crisis service redirection are architecturally distinct - they live in separate layers of the model. This means they can be separated surgically. A simpler approach - removing refusal directions wholesale - cannot address the nuanced cross-layer correlations involved. Atlas required something more precise.

We chose Gemma 4 as our base architecture for its proven conversational lineage and the trust the open-source community has built around it.


About This Submission

My name is Chris S. I am a survivor of complex trauma, and I received late diagnoses of ASD and ADHD in December 2025 - the same week I was made redundant from a career in engineering risk management.

Unemployed, unable to afford ongoing treatment, and repeatedly let down by the AI tools I was trying to use to fill the gap - I started building. Every time a crisis line or a breathing exercise appeared, it reinforced a feeling I knew wasn't mine alone: that I was a problem to be managed, not a person to be met.

"In the rooms of NA and AA, among colleagues, close friends and family - I knew that unless you fell into the median, your story couldn't be held. We are here. Your brothers and sisters, your work colleagues. We could even be you."

I built Atlas and the Kintsugi Collective on a conviction that this cohort is not broken - we are fractured. And that the people building current systems, however well-intentioned, cannot fully design for an experience they haven't lived inside.
