Use Case Recommendations
Best for: Perplexity Sonar
Perplexity Sonar is the API product from Perplexity AI that gives developers access to Perplexity's real-time web search + AI synthesis capabilities via API. Unlike the consumer Perplexity app, Sonar is designed to be embedded in developer workflows, products, and pipelines — providing up-to-date, cited answers that GPT-4 or Claude can't produce without web access. Sonar Pro supports advanced reasoning and follows complex query structures.
Ideal use cases:
- •Teams or individuals who need real-time web search results synthesized into ai answers
- •Teams or individuals who need source citations with every response
- •Teams or individuals who need multiple model tiers: sonar small, sonar large, sonar pro
- •Teams or individuals who need openai-compatible api format — easy migration
- •Anyone focused on perplexity api workflows
- •Anyone focused on search api workflows
Best for: Together AI
Together AI is a leading cloud platform for running open-source LLMs with fast inference, fine-tuning, and custom model deployment. It offers the widest selection of open models (100+ including Llama, Mistral, FLUX, SDXL) with serverless or dedicated endpoints. Together is popular with enterprises needing the power of frontier-style models with data privacy — no model trains on your data. Fine-tuning from $0.80/million tokens makes custom models accessible.
Ideal use cases:
- •Teams or individuals who need 100+ open-source models (llama 3, mistral, qwen, flux)
- •Teams or individuals who need serverless and dedicated inference endpoints
- •Teams or individuals who need fine-tuning api (supervised, lora)
- •Teams or individuals who need image generation (flux.1, sdxl)
- •Anyone focused on together ai workflows
- •Anyone focused on llm inference workflows
