# GPT-5.6 Series Launch: Official Relay + CodexReverse Groups

> OpenAI's GPT-5.6 trio (gpt-5.6-sol / terra / luna, released July 9) is live on APIYI at official price parity ($5/$30, $2.5/$15, $1/$6 per 1M tokens). The default relay group gets up to a 20% recharge bonus (~17% off), and the CodexReverse group carries a default 0.7x discount.

**2026/7/10 10:47 (UTC+8)** · New Model · OpenAI

🚀 **The three-tier GPT-5.6 series is live · open on both the official-relay and CodexReverse groups**

OpenAI's new model family, released 2026/7/9: flagship `gpt-5.6-sol` (\$5/\$30), balanced `gpt-5.6-terra` (\$2.5/\$15 — GPT-5.5-class at half the price), and lightweight `gpt-5.6-luna` (\$1/\$6, per 1M tokens). All three are priced identical to official rates and speak the OpenAI-compatible format — just change the `model` name.

Two groups to choose from, by need:

* Default official-relay group (default / svip): official API resources at official parity; recharge bonus up to 20%, effectively about 17% off
* `CodexReverse` group: Codex reverse-engineered economy channel with a default 0.7x discount; availability tracks official Codex
