The tiering given in the report is: paid users get GPT-6 Sol, free users get GPT-6 Luna. On rollout pace, this rollout starts globally the same day for Plus, Pro, Business, and Enterprise users, with free users and Go users following a day later.
Two things are not made clear here. First, the specific capability differences between GPT-6 Sol and GPT-6 Luna are not explained; second, after free users and Go users follow a day later, whether their features match the paid tiers is also unknown.
In addition, the report gives no specific parameters, context length, pricing, or available-region details for GPT-6. For a rollout aimed at "all users," the absence of this information means it is currently impossible to judge whether users across different tiers actually get the same set of capabilities.
