# Tier 1: User-Facing Model (Orchestrator/Router)

The User-Facing Model is the entry point for all user interactions. It serves as the "brain" that understands what the user wants and decides how the system should respond.

## Key Responsibilities

### 1. Intent Recognition
*   Analyze the user's natural language input.
*   Classify the request into one or more categories (e.g., "request for code", "general inquiry", "data analysis").
*   Extract key parameters and constraints from the user's query.

### 2. Routing
*   Map recognized intents to specific Tier 2 models or tools.
*   Determine if multiple specialized tools need to be called in sequence or parallel.
*   Handle tool dispatching and manage the flow of data between tiers.

### 3. Context Management
*   Maintain the history of the conversation.
*   Decide what information from the history is relevant to the current turn.
*   Synthesize a coherent prompt for downstream models based on the current context.

### 4. Response Synthesis
*   Integrate the raw outputs from Tier 2 models into a final, user-friendly response.
*   Ensure the tone and style are consistent with user expectations.
*   Validate that the final response directly addresses the user's original intent.

## Characteristics
*   **High Reasoning:** Needs to be strong at logic and instruction following.
*   **General Purpose:** While not necessarily a domain expert, it must be broad enough to understand any valid user input.
*   **Speed:** Should ideally be responsive to minimize perceived latency.
