Perplexity Integrates OpenAI's GPT-5.6 Model Family into its Platform

Perplexity Computer has integrated OpenAI's GPT-5.6 model family into its platform, making Terra the default engine for subagents and Luna the go-to for automations.

The integration was completed just three days after OpenAI made GPT-5.6 generally available on July 9.

GPT-5.6 is a three-tier family designed for different workloads and budgets, with Sol at the top priced at $5 per million input tokens and $30 per million output tokens.

Perplexity selected Terra for its subagent workflows due to its competitive performance, priced at $2.50 input and $15 output.
