OpenAI has released the new GPT-5.6 Sol version as a limited preview. It brings the newest upgrades to ChatGPT and also touches Codex. Entrance is now gated to pre-approved collaborators while proper authorities finish checks.
The preview welcomes only vetted teams working ahead of plans for wider release. OpenAI notes certain user groups are still restricted from trying the upgrade. Licenses for commercial use stay paused as oversight continues.
Final decisions rest with regulators vetting details. Once complete, OpenAI expects to open the doors much wider for everyone else.
