+## IntentGuard Model Family
+
+IntentGuard provides specialized intent classifiers for high-stakes verticals where chatbot misuse carries regulatory, legal, or safety risk:
+
+| Model | Vertical | Accuracy | Off-Topic Pass Rate | Link |
+|-------|----------|----------|---------------------|------|
+| **intentguard-finance** | Financial Services | **99.6%** | 0.00% | This model |
+| **intentguard-healthcare** | Healthcare & Clinical | 98.9% | 0.98% | [perfecXion/intentguard-healthcare](https://huggingface.co/perfecXion/intentguard-healthcare) |
+| **intentguard-legal** | Legal & Compliance | 97.9% | 0.50% | [perfecXion/intentguard-legal](https://huggingface.co/perfecXion/intentguard-legal) |
+

+
+## Overview
+
+### The Problem
+
+Enterprise chatbots in regulated industries face a critical challenge: users inevitably ask off-topic questions (sports, entertainment, relationship advice) that the underlying LLM will happily answer — exposing the organization to compliance risk, brand damage, and potential liability.
+
+Traditional keyword filters miss nuanced off-topic queries, while LLM-based guardrails are too slow and expensive for real-time inference.
 
-- **Architecture:** DeBERTa-v3-xsmall fine-tuned for 3-way classification
-- **Format:** ONNX (INT8 quantized)
-- **Version:** 1.0
-- **Vertical:** finance (Financial Services)
-- **Publisher:** [perfecXion.ai](https://perfecxion.ai)
+### The Solution
+
+IntentGuard uses a tiny, purpose-trained DeBERTa-v3-xsmall model (22M parameters, 2.5MB quantized) to classify user intent in <30ms on CPU. The three-way classification (`allow`/`deny`/`abstain`) enables precise control:
+
+- **Allow** — On-topic for the vertical, pass to the LLM
+- **Deny** — Clearly off-topic, block with a polite redirect
+- **Abstain** — Ambiguous, escalate to secondary classifier or human review
