# AI System Fact Sheet

Model card · Effective July 23, 2026

How Trooth's AI features work, so you can judge how far to rely on them. Updated as the systems change.

Contact: [hello@trooth.co](mailto:hello@trooth.co)

## What the AI does

Two features use AI: **Kyrie**, a conversational assistant, and **questionnaire drafting**, which proposes answers to security and vendor questionnaires. Both draft and explain; a person decides.

## Foundation models

Both run open-weight models, not trained by Trooth, on Cloudflare Workers AI inside the product's network, under terms excluding inputs and outputs from training; Cloudflare is a listed sub-processor. These commitments hold if the model changes.

## Feature by feature

Each model and its inputs, checked against running code on September 26, 2026. Cloudflare picks the location; no feature pins a region or falls back to another provider.

| Feature | Model | What the model sees | Stored by Trooth |
| --- | --- | --- | --- |
| Kyrie, the assistant on trooth.co | Workers AI: `@cf/baai/bge-base-en-v1.5` to find passages, `@cf/meta/llama-3.3-70b-instruct-fp8-fast` to write the answer | Your question, curated knowledge-base passages and, when you are signed in, your company's posture summary | A count of requests for rate limiting; not the question |
| Questionnaire drafting | Workers AI: `@cf/meta/llama-3.1-8b-instruct` | The question being drafted and your own workspace's witnessed evidence | The draft you keep, in your workspace |
| trooth_ask, the Model Context Protocol (MCP) knowledge tool | None: a fixed, curated knowledge base and a capability registry, matched by keywords | Not applicable | That a question was asked; not its text |

Anthropic is on the sub-processor list for internal use by Trooth's founder. No customer-facing feature sends customer data to it.

## What data the models see

A model sees **only what its task needs**: your prompt, witnessed evidence and posture data, and framework references. It does not receive credentials or integration secrets.

**Trooth does not use your data to train AI models,** and prompts are not contributed to provider training. The [AI Use Policy](https://trooth.co/ai-policy) states the full stance.

## Limitations

- Output reflects the evidence available at the time and can be out of date.
- Models reason over language, not a ground-truth audit, and can miss nuance in your environment.
- Drafts start security and compliance work; they do not replace professional judgment.

## Hallucination disclosure

Like all large language models, these can produce confident, inaccurate or fabricated output, so **a person should review it** before you rely on or submit it. Trooth labels AI content and keeps a person in control of real effects.
