Key Features

• System message support for model behavior control

• Message history for conversation context

• Image input support (GPT-4 Turbo, GPT-4o)

• Forced JSON output option (GPT models only)

• Citation control for Perplexity models

Citation Formats (Perplexity Models)

When using Perplexity models, you can control how citations are included in the response: 1. No Citations: Citations are completely omitted 2. Append to Text: Citations are added at the end of the response text 3. Separate JSON: Response is formatted as a JSON object:

{
    "content": "The AI-generated response text...",
    "citations": [
        "https://source1.com/article",
        "https://source2.com/reference",
        ...
    ]
}

Usage Tips

• Lower temperature (0.1-0.3) for factual/consistent responses

• Higher temperature (0.7-0.9) for creative content

• Use system messages to define role and constraints

• Chain responses using message history

• For structured data, enable JSON output and specify format in prompt

• When using Perplexity, choose citation format based on your needs:

• Use "Append to Text" for human-readable output

• Use "Separate JSON" for programmatic processing of citations
