?? GPT-4o: Fast, Multimodal, and Free for Everyone
GPT-4o is the default Perplexity AI model for free users. It's capable of understanding and responding to text, image, and code inputs with impressive coherence and creativity. Unlike its predecessors, GPT-4o operates at turbo speed and is optimized for real-time interaction.
Use GPT-4o when you're:
? Engaging in natural conversation or AI chat
? Analyzing charts or diagrams
? Generating social media content
? Translating languages on the fly
?? Claude 3.5 Sonnet: Logical Brilliance & Research Strength
The Claude 3.5 Sonnet model, released by Anthropic in 2025, is considered one of the most reliable models for tasks that require step-by-step reasoning and high factual accuracy. It's also known for being more "humanlike" in tone and less prone to hallucination, making it ideal for academic or technical writing.
Perfect for:
? Deep Q&A and literature summaries
? Writing documentation or technical guides
? Handling large input contexts with accuracy
?? Mistral Models: Lightweight and Open-Source
Perplexity AI includes support for both Mistral 7B and Mixtral models — two of the leading open-source LLMs designed to be fast and efficient. These are well-suited for users who prioritize cost-efficiency and open architectures.
Choose Mistral if you're:
? Running simple code generation tasks
? Conducting quick information retrieval
? Working in resource-constrained environments
?? Command R+: Retrieval-Augmented Generation Expert
Cohere’s Command R+ is specifically optimized for Retrieval-Augmented Generation (RAG), making it an ideal Perplexity AI model for enterprise-level document summarization or contract analysis. When you ask a question, it pulls verified answers directly from referenced documents or links, reducing the risk of misinformation.
Best for:
? Legal and financial document summarization
? Transparent sourcing and citations
? Search-based writing with references
?? Performance Comparison of Perplexity AI Models
| Model | Best For | Speed | Accuracy |
