Chong-Zhen ChatGPT Top-up is a service that enables users to purchase ChatGPT Plus and Pro subscriptions. It processes payments through Alipay and activates subscriptions within one to three minutes without requiring users to provide their account passwords or have a foreign credit card. The service offers multiple subscription tiers, including Plus and Pro with increased usage limits. Pro plans provide higher Codex quotas, with options for 10x and 20x the standard allowance. All plans include access to the latest OpenAI models, such as GPT-6-Astra and Image 2.5, and support for Codex across applications, command-line interfaces, and web platforms. The service includes a 30-day warranty and provides official invoices for corporate reimbursement. Typical use cases include individual users seeking convenient subscription top-ups and businesses requiring bulk purchases with corporate contracts. The workflow involves selecting a plan, completing payment via Alipay, and receiving confirmation through an order system that supports tracking and after-sales communication. The service is designed for users who need a streamlined process for managing ChatGPT subscriptions without direct payment methods.
