Most AI tools only offer monthly subscription-based pricing, and as usage increases, they start imposing more and more limitations due to cost considerations. For example, ChatGPT Plus restricts GPT-4 to only 25 requests every 3 hours. Even users who don't use the service frequently have to pay a $20 monthly subscription fee. Meanwhile, users with high usage like myself find it inadequate. The traditional monthly subscription model does not allow everyone to access AI capabilities fairly based on their computing needs. Zecoba AI offers a pay-as-you-go option, allowing users and developers to pay only for the number of times they use the service without expensive subscription fees.
