Why Choose OpenAI o4-mini Interface?#
OpenAI's o4-mini model is its latest generation lightweight model, designed specifically for developers, balancing performance and cost. It excels in scenarios such as natural language processing, code generation, and data analysis, making it suitable for small and medium-sized enterprises and individual developers. Unlike the ChatGPT Plus subscription, the API interface allows for more flexible customized development, capable of seamless integration into your applications. However, applying for API access requires completing steps such as account registration, payment verification, and permission application, and domestic users may need to use specialized payment tools due to payment channel restrictions.
Challenges for Domestic Users Applying for OpenAI API Access#
Domestic users often encounter the following issues when applying for OpenAI API access:
- Payment Restrictions: OpenAI only supports international credit card payments such as Visa and MasterCard, and UnionPay cards issued domestically usually cannot be used directly.
- Network Environment: Access to the OpenAI official website may be unstable due to regional restrictions, requiring a stable overseas network environment.
- Account Verification: Some users may be rejected when binding payment methods due to risk control by payment channels.
To address these issues, WildCard has become an ideal choice for domestic users. It is a subscription card for overseas software services designed specifically for domestic users, supporting recharge through Alipay and WeChat, with simple and stable operations, avoiding the complex processes of needing to recharge through USDT like Dupay, VCard, PokePay, WasabiCard, or LocalCard.
