OpenAI01.net

Chat01.ai (formerly OpenAI01.net) is a cost-effective web platform offering access to a variety of advanced AI language models, including GPT-5.5, GPT-5.4, o3, GPT-4.5, and gated premium variants like GPT-5.5 Pro and research models. Designed for heavy AI users, developers, and researchers, it provides a straightforward chat interface where users select a model and ask questions. The platform uses a credit system: free users receive 2 daily credits, while paid subscriptions (Starter $9.99/mo, Basic $19.99/mo, Pro $39.99/mo) grant 30, 100, or 300 daily credits respectively, along with unlimited question frequency and access to o1 vision and o1-pro models. Pay-as-you-go credit packages (200, 500, or 3000 permanent credits) are also available for flexible spending. Key features include continued asking (conversation memory), hidden Q&A, and optional priority customer support on the Pro tier. The referral program offers 10 credits per invite, allowing users to extend free usage. Different models cost varying credits per query—basic models like gpt-5-5 cost 1 credit, while premium models like gpt-5-5-pro cost 20 credits and require a paid plan. The interface is simple and focused on individual Q&A, without API access, mobile apps, or team collaboration features. Chat01.ai competes directly with ChatGPT Pro by offering a more affordable pay-as-you-go and subscription model for accessing similar high-end models. It is best suited for cost-conscious users who need frequent, low-cost access to top-tier AI without the high monthly fee of alternatives like OpenAI's $200/mo Pro tier. However, the lack of API and enterprise features limits its appeal for developers needing programmatic access or teams requiring shared workspaces. For pure web-based conversational AI at a lower price point, Chat01.ai is a strong alternative.
