OpenAI quietly updated its ChatGPT Pro page, renaming tiers to Pro Standard and Pro More while removing specific usage multipliers in favor of vague promises. A new Pro Max tier, potentially priced at $500 monthly, is expected to launch at DevDay, offering ultra-fast performance for GPT-6 Astra. While some view this as necessary tiered pricing for resource-intensive models, critics argue the lack of transparency reduces existing user benefits. The official unveiling of Pro Max remains the key focus ahead of Tuesday's developer conference.
