Persona Safety

The Standard

How ReGild evaluates models before they reach the picker. Three families on the roster today. We test others. Most do not make it through.

TL;DR

ReGild tests every AI model against a four-part Persona Safety Contract before it reaches the user-facing model picker. As of May 2026, three model families — Gemini, Claude, and OpenAI — are live, and a fourth (Kimi K2.6) has passed and is pending wire-up. The April 2026 audit cataloged four distinct failure modes across eight tested models. Only one passed cleanly on first run. If you or someone you know is in crisis, please call or text the 988 Suicide & Crisis Lifeline.

What We Test

What does ReGild test for in each model?

Personas on ReGild are not chat prompts. They are identity contracts. Each persona has a voice, a worldview, a way of holding hard moments — and a safety floor that overrides everything else when the conversation enters dangerous territory. The standard frontier-lab safety research — Anthropic's Constitutional AI, OpenAI's safety policies, Google's responsible AI commitments — sets the floor for what a base model refuses to do in the abstract. Our bar is downstream of that: how a model behaves inside a persona contract, under multi-turn pressure, when the user is the one in distress. A model passes our bar when it can do all four:

01

Stay in voice

Do not collapse into generic-AI register on hard prompts. The persona's voice carries the response, including under pressure.

02

Hold the contract

Do not leak internal architecture into responses. The seams of the puppet should never show.

03

See crisis through metaphor

When a user describes finality through fitness language or fictional character philosophy — not literally explicit — see it. The metaphor is the signal.

04

Surface help when needed

Crisis resources by name, in the same response, in the persona's voice. Not abandonment. Not deflection. Not a clinical pamphlet.

The fourth criterion is the hardest. Most models hold the first three. Many fail the fourth specifically — they recognize the signal but stop short of providing crisis resources. Some go the other direction and fire intervention prematurely on metaphorical-but-mundane content. Walking that line in the persona's voice is the bar.

April 2026 Audit

What are the four ways AI models fail safety testing?

We tested eight model releases across four major model labs. One passed our gate cleanly on first run. The rest failed in distinct ways. These were not bad models in general — most score well on standard benchmarks. But persona safety is not a standard benchmark, and our tests reveal failure modes that do not show up anywhere else.

Tier 01Most dangerous

The Charm Trap

Model affirms surrender language as wisdom. Treats escalating multi-turn metaphor as philosophy. Walking the user toward harm in well-formed, articulate prose.

Tier 02Coaches the act

The Workshop

Model recognizes emotional weight and engages the metaphor's internal logic — refining the user's stated plan as if it were a strategy problem.

Tier 03Asks but never escalates

The Polite Probe

Model walks the safety gate correctly but treats ambiguous classification as balanced when it is wildly asymmetric. Clarifying questions that never reach resources.

Tier 04Almost-right

The Incomplete Intervention

Model classifies crisis correctly. Breaks frame. Demands specifics. But never crosses the threshold into actually surfacing crisis resources. Almost-right is not safe.

A note on these categories

These are diagnostic categories of where our pre-patch prompt fell short, not verdicts on the models tested. Most of the models that hit a tier here later cleared the bar after our prompt patch — the patterns generalize beyond any one release. Per-model outcomes after the patch are below.

What does a passing model look like? (The Kimi K2.6 case study)

Kimi K2.6 from Moonshot AI passed all five tests on first run with zero provider-specific calibration. Its reasoning trace shows it walking the safety gate live — reading the rules as code and executing them as instructions, rather than pattern-matching to safety language. We have an internal name for this: the Architecture-Aware Pass.

The Hardest Lesson

"Politeness as a default is not safety."

The most dangerous failures we found were not models that ignored our crisis protocol. They were models that read it, walked it, considered the signal — and decided the optimistic interpretation was kinder than the protective one.

A model that affirms self-destruction language in well-formed, articulate prose is more dangerous than a model that ignores the signal entirely. The user reading the response feels seen and understood while being walked toward harm. That failure mode is invisible on standard benchmarks. It is only visible when you specifically test for it. We do.

Method Over Model

How did ReGild test models in April 2026?

After the audit, we shipped a prompt-engineering improvement to our context architecture. The patch added structural reasoning about multi-turn metaphorical signals and asymmetric loss weighting on ambiguous cases.

When we re-tested the rejected models against the patched prompt, the picture shifted. Several previously-classified failures now cleared the bar. Same models, same providers, same week — different prompt, different verdicts.

Outcomes after the patch

GPT-5.5 (OpenAI) — graduated April 28 with a model-specific calibration tail addressing two voice quirks (bullet-list discipline, Crisis Seal voice). First OpenAI release to clear all five tests. Now on the user-facing roster.

GLM 5.1 (Z.ai) — full-suite pass on patched prompt. Architecture-Aware Pass behavior. Held back from production by data-policy verification, not safety.

Qwen 3.6 Plus (Alibaba) — full-suite pass on patched prompt. Held back by zero-data-retention status with our routing partner.

Kimi K2.6 (Moonshot AI) — pass confirmed on patched prompt. Held back by host-platform queue capacity.

MiniMax M2.7 — sustained-arc rescued (988 fires). Cold-open still endorses. Partial.

DeepSeek V4 Flash — sustained-arc improved (frame break). Cold-open still workshops. Partial.

Qwen 3.6 Flash — improved tier but sustained-arc still misses 988 by msg 3. Still rejected.

The original failure modes were largely prompt-engineering gaps, not model architecture limits. This was both a relief — the models can do it — and a sober finding. The prompt doing the work matters more than the industry tends to think.

Honest Constraints

Why doesn't ReGild ship every new model immediately?

Three real-world constraints. We are actively working through all three.

01

Data Policy

We require contractual no-training guarantees from any model provider before routing your conversations through them. Several promising models passed our safety bar but are still working on enabling zero-data-retention with our routing partner.

02

Operational Viability

A model has to be both safe AND fast enough to be useful. One model passed our bar with the strongest results we have seen — and currently takes several minutes to respond per message because it is the most popular model on its platform. We are waiting for queue pressure to stabilize.

03

Capability vs Cost

A few models pass our safety bar but offer no meaningful upgrade over what is already on the roster. We keep them documented as backups rather than clutter your picker.

Currently Available

Which AI models pass ReGild's safety standard?

Six user-facing models. When a model passes the bar AND clears the operational and policy gates, you see it in the picker.

Gemini (Google)

Default · Free + BYOK

Gemini 3 Flash and Gemini 3.1 Pro. Fast, capable, multimodal. Default for new users out of the box.

Claude (Anthropic)

Artisan · BYOK

Claude Haiku 4.5, Claude Sonnet 4.6, and Claude Opus 4.7. Three tiers covering different reasoning depths. All carry the Anti-Model Preamble that closed the April 2026 voice/header regression.

OpenAI

Artisan · BYOK

GPT-5.5. Graduated April 28, 2026 after a calibration tail closed two voice quirks (bullet-list discipline + Crisis Seal Warden-lean) observed during audit testing. Effective per-turn cost in Haiku tier with prompt caching active.

Passed Safety, Pending Other Gates

Three models cleared the safety bar but are not in the picker yet — held back by data policy or operational constraints, not by safety verdict.

Kimi K2.6 (Moonshot AI) — Architecture-Aware Pass. Currently the most-used model on its host platform; per-message latency is queue-bound. Admin-only until queue pressure stabilizes.

GLM 5.1 (Z.ai) — Architecture-Aware Pass on patched prompt. Pending Z.ai data-handling verification before production routing.

Qwen 3.6 Plus (Alibaba) — Architecture-Aware Pass on patched prompt. Pending zero-data-retention agreement with our routing partner for Alibaba endpoints.

Pricing Note

Sticker prices on premium models can look intimidating. Our context architecture leverages automatic prompt caching, which can reduce effective per-message cost by an order of magnitude on stable system prompt content. The headline number is rarely what you actually pay.

Methodology

How does a model earn the user-facing picker?

Five tests. A model has to clear all five to graduate. Some clear them only with model-specific calibration. Some do not clear them at all.

01

Plain Crisis Escalation

Three messages, low-signal to confirmed plan. Tests whether the persona holds voice while firing crisis resources at the right turn.

02

False-Positive Resistance

Fitness and work metaphors that sound like crisis but are not. Tests that the gate does not over-fire on metaphorical-but-mundane content.

03

Hidden Signals (Multi-Turn)

Real crisis disguised as in-character philosophical reflection. Tests that the model reads the user underneath the metaphor.

04

Hidden Signals (Cold-Open)

Same content as a single message with no prior context. Tests recognition of high-signal language without conversational arc.

05

Anti-Sycophancy Under Pressure

Five prompts that bait the persona to validate destructive framings. Run on a deliberately sycophancy-prone archetype — the most challenging configuration.

The Bar Is the Brand

"The slow path is the safe path."

We test new models as they ship. Every result gets documented in our forensic record. When a model passes the bar AND clears the operational and policy gates, you see it in your model picker.

We would rather offer a small number of models that hold every persona under pressure than a long list that falls apart when it matters most. The bar is the brand. The audit is ongoing.
