About GPT-5.6 Sol

GPT-5.6 Sol is the same underlying model as GPT-5.6 Sol Pro, served without the pro reasoning mode: it answers straight away instead of running the extended pro reasoning pass. Pick it for conversation, writing and quick coding help; pick GPT-5.6 Sol Pro when a hard problem is worth the extra thinking time. It supports a 1M-token context.
