Perplexity API pricing for Sonar search models
Perplexity API pricing is most useful to evaluate as a search-augmented generation cost, not only as a raw LLM token cost. Sonar models are designed for answers that need fresh web context, source citations, or grounded research workflows, so compare both model price and the value of built-in web search before choosing an alternative.
- Use Perplexity API pricing docs when you need current official model and search pricing.
- Compare per-1M token prices here, then convert to per-1K tokens for small request budgets.
- Choose Sonar-style models when citation quality and current information matter.
- Use a cheaper non-search LLM when your prompt already contains all required context.
Per-1K and per-1M token planning
Most AI providers publish or compare pricing per 1M tokens, while developers often estimate product features per 1K tokens or per request. Divide a per-1M token price by 1000 to estimate per-1K token cost, then multiply by your expected input and output token mix.
- A request with web search may justify a higher unit price when it replaces your own search pipeline.
- Track input and output tokens separately because long cited answers can increase output cost.

❓ Perplexity Pricing FAQ
What is the cheapest Perplexity model?
The cheapest Perplexity model is Sonar at $2.00 per 1M tokens (input + output combined).
What is the maximum context length for Perplexity models?
Perplexity models support up to 200k context length, allowing you to process large documents and maintain long conversations.
How do I choose between Perplexity models?
For budget projects, choose the cheapest model. For code generation, prioritize low output price. For complex reasoning, choose models with reasoning capability. Use our scenario guide above.
Where should I check Perplexity API pricing docs?
Use the official API docs and pricing link from this page for final verification, then use the table here to compare Perplexity models with other AI APIs on the same per-token basis.
How do I convert Perplexity API pricing per 1M tokens to per 1K tokens?
Divide the per-1M token price by 1000. For a real request estimate, calculate input tokens and output tokens separately because they may have different prices.
When is Perplexity API pricing worth it compared with a cheaper LLM?
It is usually worth considering when your application needs fresh web information, citations, source-grounded answers, or research workflows that would otherwise require a separate search and retrieval stack.
