Route mode sends requests containing PII to a local LLM. Requests without PII go to OpenAI or Anthropic.

​
How It Works

Request with PII

Routed to Local LLM (Ollama, vLLM, llama.cpp, etc.)PII stays on your network.

Request without PII

Routed to OpenAI or AnthropicFull performance.

​
When to Use

  • Have local GPU resources
  • Need complete data isolation for sensitive requests
  • Must prevent any PII from leaving your network

​
Configuration

mode: route

providers:
  openai:
    base_url: https://api.openai.com/v1

local:
  type: ollama
  base_url: http://localhost:11434
  model: llama3.2
In route mode:
  • No PII detected → Request goes to OpenAI or Anthropic
  • PII detected → Request goes to local LLM
For Anthropic requests, the local LLM must support the Anthropic Messages API (e.g., Ollama with Anthropic API compatibility).

​
Local LLM Setup

​
Ollama

local:
  type: ollama
  base_url: http://localhost:11434
  model: llama3.2

​
vLLM

local:
  type: openai
  base_url: http://localhost:8000/v1
  model: meta-llama/Llama-2-7b-chat-hf

​
llama.cpp

local:
  type: openai
  base_url: http://localhost:8080/v1
  model: local

​
LocalAI

local:
  type: openai
  base_url: http://localhost:8080/v1
  model: your-model-name
  api_key: ${LOCAL_API_KEY}  # if required

​
Response Headers

Route mode sets these headers on responses: When a request is routed to local: 
X-PasteGuard-Mode: route
X-PasteGuard-Provider: local
X-PasteGuard-PII-Detected: true
X-PasteGuard-Language: en
When routed to OpenAI or Anthropic: 
X-PasteGuard-Mode: route
X-PasteGuard-Provider: openai
X-PasteGuard-PII-Detected: false
X-PasteGuard-Language: en
If the detected language wasn’t configured and fell back to fallback_language: 
X-PasteGuard-Language-Fallback: true
