Search models

How Meridian routes queries to live search APIs.

Built-in providers

Meridian ships with native integrations for Perplexity Sonar, Brave Search, and Tavily. Each provider exposes a distinct model ID you can pass to the chat completions endpoint.

Perplexity & OpenAI compatibility

Perplexity Sonar models speak the OpenAI chat-completions wire format. If you hold your own pplx-key you can point any OpenAI-compatible client directly at https://api.perplexity.ai. Meridian does not bridge or proxy Perplexity traffic — customers bring their own keys and call Perplexity directly.

Model IDs

  • perplexity/sonar-pro — deep research with citations
  • perplexity/sonar — fast, cost-effective search
  • brave/search — web + news index
  • tavily/search — AI-optimized results
