GPT 5.6 Terra and Luna are now live in Perplexity Computer.
Terra is the new default model for all Computer subagents, while Luna will serve as the primary model for scheduled automations.
Terra is also available as an orchestrator model in Computer.
GPT-5.6 Terra and Luna just got price cuts from @OpenAI.
OpenRouter is cheaper still. Our 50% exclusive discount applies on top, bringing Luna to $0.1/M in $0.6/M out and Terra to $1/M in and $6/M out.
Scale your workloads with luna:
GPT-5.6 Sol, running in Codex, helped make GPT-5.6 cheaper to run.
It rewrote production GPU kernels and helped improve the smaller model used to speed up generation.
Kernel improvements helped cut end-to-end serving costs by 20%.
GPT-5.6 Sol sets a new state of the art in cybersecurity on “The Last Ones” cyber range.
We’re already seeing that capability translate into defensive outcomes: helping teams find, validate, and fix vulnerabilities in real-world code.
Put it to work with Codex Security:
GPT-5.6 sol is half the price and ~twice as token efficient as fable in many cases for accomplishing the same task.
happy to deliver at one-quarter of the price.
GPT-5.6 is a major step forward for health intelligence.
Across the lineup, we’re delivering stronger performance at lower cost: GPT-5.6 Luna outperforms GPT-5.5 at its highest reasoning setting while costing 25x less.
Together, these advances raise quality while making advanced models accessible to more people globally.
