Perplexity Computer has rolled out OpenAI’s GPT-5.6 model family across its platform, making Terra the default engine for subagents and Luna the go-to for automations. The integration, completed by July 12, was just three days after OpenAI made GPT-5.6 generally available on July 9.
What GPT-5.6 actually brings to the table
OpenAI’s GPT-5.6 isn’t a single model. It’s a three-tier family designed for different workloads and budgets.
Sol sits at the top, built for complex reasoning and coding tasks, priced at $5 per million input tokens and $30 per million output tokens. Terra occupies the middle ground, offering competitive performance at $2.50 input and $15 output. Luna is the budget option at $1 input and $6 output, optimized for speed over depth.
Perplexity selected Terra for its subagent workflows, where multiple AI agents collaborate on research, coding, and project management tasks. Luna handles the repetitive automation layer, the kind of work where raw speed matters more than nuanced reasoning.
Why crypto should be paying attention
Projects building decentralized AI agent frameworks are competing for the same fundamental use case that Perplexity just upgraded: orchestrating multiple AI models to complete complex, multi-step tasks. The difference is that Perplexity can integrate GPT-5.6 in three days. Decentralized alternatives face additional latency from consensus mechanisms, token-gated access layers, and smart contract…
