GPT-5 Is Already Here: From Orion Rumors to GPT-5.6
The earlier version of this page treated GPT-5 as an upcoming model and repeated unverified Orion and Spud release claims. That information is obsolete. OpenAI released the GPT-5 generation in 2025 and launched the GPT-5.6 family on July 9, 2026.

This page replaces an older version that contained outdated or unsupported claims.
Verified facts
GPT-5.6 is generally available across ChatGPT, Codex and the OpenAI API.
The GPT-5.6 family includes Sol as the flagship, Terra for balanced everyday work and Luna as the most cost-efficient option.
OpenAI's current announcement does not support the old claim that an upcoming GPT-5.5 product called Spud was weeks away.
Orion was associated with earlier reporting and should not be used as the current name for GPT-5.6.
What readers should do now
- Choose among the current GPT-5.6 models based on task difficulty, latency and budget rather than waiting for the rumored release described in the old article.
- Check the official model and API pages before committing to pricing, limits or a migration plan.
- Run your own evaluation set before changing a production model because capability and cost vary by workload.
