Perplexity's Agent API adds Claude Sonnet 5.5
By Steven Van ·
Claude Sonnet 5.5 costs $2 per million input tokens and $10 per million output tokens, and Anthropic requests must set max_output_tokens.
The Agent API in Perplexity now supports Claude Sonnet 5.5, listed in the Agent API Models reference under the model ID anthropic/claude-sonnet-5-5.
Perplexity lists it at $2.00 per million input tokens and $10.00 per million output tokens, with cache reads at $0.20 per million. It uses default processing only, with no optional service tiers.
Requests to any anthropic/* model must include max_output_tokens. If it is left out, the API returns HTTP 400.
