GPT-6 Sol rolls out within three days, with setup advice and observed changes
A leaker says most users will get Sol within three days and advises rebuilding custom instructions, citing stronger 3D reasoning, creative writing, long-conversation continuity and recall of old memories.
Over the next three days, most of you should start getting GPT-6 Sol, and I already have a few recommendations. First, partially reset the custom instructions you built around GPT-5.6 Sol. Some of them actually make 6 Sol worse. Rebuild them around the new model, update your memories, and tune its style for your own use cases. This makes a surprisingly huge difference, especially in writing. The new checkpoint also behaves differently in formatting. Some bolding disappears, some paragraph breaks change, and markdown can feel slightly less consistent until your instructions are adjusted. As for the actual improvements, the biggest ones I’ve noticed so far are: → much stronger 3D/spatial reasoning → significantly better creative writing and tone control → better continuity across long conversations → much stronger retrieval of old memories and details from months ago → better adaptation to your personal writing style over time Do not treat it like “5.6 Sol, but smarter.” It responds much better when you rebuild your setup around it.
