lnvariant · reddit · 2026-07-11
The post asks which model is actually better: GPT 5.5 Pro Extended or GPT 5.6 Sol Pro.
The author mentions they have been using gpt 5.5 pro extended thinking but are unsure about the actual performance of gpt 5.6 sol pro, especially since the latter seemingly lacks an extended thinking mode.
The core message is straightforward: it's an inquiry about the user experience of these two model versions, focusing on their capability differences and whether switching is worthwhile.
