# XO GPT User Query Paraphrasing Model

<Badge icon="arrow-left" color="gray">[Back to XO GPT Model Specifications](/ai-for-service/generative-ai-tools/xo-gpt-module#xo-gpt-model-specifications)</Badge>

The XO GPT User Query Paraphrasing model improves NLP accuracy by expanding and rephrasing user queries using conversation context. It resolves co-references and ambiguities before the query reaches downstream NLP components, enabling more accurate intent detection and entity recognition.

***

## Challenges with Commercial Models

| Challenge | Impact |
| - | - |
| **Latency** | High processing times affect user experience in real-time or high-volume scenarios. |
| **Cost** | Per-request pricing scales poorly for large deployments. |
| **Data Governance** | Sending queries to external models raises privacy and security concerns. |
| **Lack of Customization** | General-purpose models aren't tuned for specific industries or use cases. |
| **Limited Control** | Minimal ability to correct or refine model behavior for incorrect outputs. |
| **Compliance Constraints** | Some industries have regulatory requirements that commercial LLM providers don't fully support. |

***

## Key Assumptions

* Designed for text-based conversations only.
* Paraphrases the user query only when it references or co-refers to details from prior conversation context. Other queries are passed through unchanged.

## Benefits

### Contextual Communication

Adapts user queries to the conversation context, enabling accurate intent interpretation for meaningful interactions. See [Model Benchmarks](#model-benchmarks) for performance insights.

### Cost-Effective

For Enterprise Tier customers, XO GPT eliminates commercial model usage costs. Example comparison (100 input tokens/conversation, 10,000 daily interactions, 15 tokens/response):

| Model | Input \$/MTok | Output \$/MTok | Input \$/Year | Output \$/Year | Total \$/Year |
| - | - | - | - | - | - |
| GPT-4 Turbo | \$30 | \$60 | \$10,950 | \$3,285 | \$14,235 |
| GPT-4 | \$10 | \$30 | \$3,650 | \$1,643 | \$5,293 |
| GPT-4o Mini | \$0.15 | \$0.60 | \$54.75 | \$32.85 | \$87.60 |

### Enhanced Security

No client or user data is used for model retraining.

**Guardrails:** Content moderation, behavioral guidelines, response oversight, input validation, and usage controls.

**AI Safety:** Ethical guidelines, bias monitoring, transparency, and continuous improvement.

<Note>
  Performance, features, and language support may vary by implementation. Test thoroughly in your environment before production use.

## Use Cases

| Domain | Use Cases |
| - | - |
| Customer Support | Simplify complex queries for accurate intent detection; remove ambiguous references; enable contextual continuity across turns |
| Healthcare | Simplify complex patient inquiries; eliminate co-references for precise understanding of patient history or treatments |
| Banking & Finance | Clarify account action queries; simplify follow-up queries about previous interactions; clarify ambiguous product inquiries |
| Education | Clarify multi-part or context-heavy student queries; simplify questions about schedules or course content |
| Human Resources | Clarify ambiguous HR questions about benefits or leave policies; rephrase workplace policy questions |
| Legal | Simplify user queries about legal contracts or policies; clarify complex legal questions |
| E-commerce | Rephrase follow-up queries about orders or shipments; eliminate ambiguities in return/refund queries |
| Social Media | Clarify questions about flagged content or platform policies; simplify account settings or privacy queries |
| IT Support | Rephrase vague or context-dependent technical queries; eliminate co-references in user-reported issues |
| Travel & Hospitality | Clarify multi-part or ambiguous booking inquiries; simplify questions about changes to travel plans |

## Sample Output

**Conversation:**

```
User: Hi, can you help me select a University for studying Physics?
AI Agent: Sure, here are some top universities for Physics:
         1. Harvard University  2. MIT  3. Stanford  4. University of Cambridge.
         Which sounds best to you?
User: Which one is best in fee structure?
AI Agent: Generally, the most affordable undergraduate tuition for Physics is at Stanford.
User: Ok, I'll choose that one.
```

**Paraphrased query:**

> User: Ok, I will choose to apply at Stanford University for a Physics course.
