The Charm of Claude 4: Why It's Worth a Try?#

Claude 4 excels in language generation, logical reasoning, and contextual understanding, especially demonstrating higher accuracy and human-like expression when dealing with complex problems. Compared to the GPT series, Claude 4 takes safety a step further, effectively avoiding the generation of inappropriate content, making it particularly suitable for academic research, content creation, and enterprise-level applications. Even more exciting is that Claude 4 offers a free trial entry, allowing users to experience its powerful features without payment.

However, while the free trial is great, unlocking the full potential of Claude 4 (such as higher usage limits or API calls) requires subscribing to a paid plan or recharging the API. Since Claude's payment system mainly targets international credit cards, domestic users often face obstacles due to a lack of suitable payment methods. Traditional virtual cards like Dupay, VCard, PokePay, WasabiCard, or LocalCard often rely on USDT recharges, which are complex and carry exchange rate fluctuation risks. In contrast, the virtual credit card that supports Claude — WildCard, with its convenient Alipay/WeChat recharge method and stable payment channels, has become the top choice for domestic users.
