What moved
Go ['GPT-5.5'] · Plus ['GPT-6 Astra','GPT-5.6 Sol','GPT-5.5'] · Pro 5×/20× ['GPT-6 Astra','GPT-5.6 Sol Pro','GPT-5.6 Sol'] → Go ['GPT-5.6 Luna'] (GPT-5.5 dropped) · Plus + GPT-5.6 Terra + GPT-5.6 Luna · Pro 5×/20× + GPT-5.6 Terra + GPT-5.6 Luna
Compare-table sync: GPT-5.5 is not a named row and sits under "Legacy models" = Go No, so it is dropped from Go (its Luna row is Yes) while staying on Plus (Legacy = Plus Yes, own 15-80 Codex column). Terra (Plus Yes / Pro Unlimited*) and Luna (Yes everywhere) added to Plus and both Pro tiers; GPT-5 Thinking Mini (Go Yes) not stored — not in the model registry.
