What moved
GPT-6 Sol was the newest Sol-generation Codex model on ChatGPT Plus, Pro 5x and Pro 20x → GPT-6.1 Sol added to ChatGPT Plus, Pro 5x and Pro 20x - 15-160 local messages per 5h on Plus, 50 credits input / 2.5 cached / 250 output per 1M
OpenAI launched GPT-6.1 Sol across its Codex rollout: the models page states the launch rollout includes Plus, Pro, Business, Enterprise and Edu and that Free and Go are excluded, and the Codex pricing page lists it at 15-160 local messages per 5h on Plus (GPT-6 Sol: 15-150) at 50 credits input / 2.5 cached / 250 output per 1M (GPT-6 Sol: 50/5/250) - the same input and output for a cheaper cached read. Its API row is $2.00/$10.00 per 1M with a $0.10 cached read and $2.50 cache write. Free and Go keep GPT-6 Luna only. The Pro 5x / Pro 20x message tables published earlier are gone from the live page, which now states that Pro plans have no five-hour limit, so those two plans gain the model without a message figure.
