OpenAI has released the new GPT-5.6 Sol version as a limited preview. Featuring cutting-edge enhancements to ChatGPT and also touches Codex. Entrance is now gated to pre-approved collaborators while a key review takes place.
The preview welcomes only vetted teams working ahead of plans for wider release. OpenAI notes some audience blocks remain off-limits from trying the upgrade. Licenses for commercial use stay paused as oversight continues.
Final decisions rest with government panels reviewing impact. Once complete, OpenAI expects to open the doors much wider for everyone else.
