302.ai

302.AI is an enterprise-grade AI resource aggregation platform that brings together top AI models and services worldwide under an innovative zero-monthly-fee, pay-as-you-go model.

Core capabilities

• All-model API aggregation: One-stop access to nearly every mainstream large model, including OpenAI, Claude, Gemini, and DeepSeek, with unified interface management
• AI application marketplace: 40+ ready-to-use tools spanning AI chat, drawing, video, music, document editing, PDF processing, and more
• Model fusion innovation: The original "-web-search" suffix adds web search capability to any model, while "-r1-fusion" enables reasoning enhancement
• Separation of admin and usage: An innovative sharing model where admins configure once and share with one click, and users can start without logging in
• Open-source ecosystem: 55 open-source projects across domains, supporting private deployment and secondary development

Use cases Low-frequency AI users who do not want to pay monthly fees, users exploring multiple AI models to find the best fit, small-to-medium businesses that need AI capabilities on a limited budget, developers who need to integrate multiple AI model APIs quickly, enterprises that need team collaboration and sharing features, and users in China who struggle to access international AI services directly.

Unique strengths Compared with official platforms like OpenAI and Anthropic that require multiple registrations and subscriptions, 302.AI offers one-stop access with pay-as-you-go billing and balances that never expire. Compared with API aggregators like OpenRouter, it goes beyond APIs with ready-to-use online apps and its unique model fusion feature. It is exceptionally friendly to users in China, solving access and payment hurdles.

Editor's recommendation 302.AI's pay-as-you-go model breaks the subscription trap of "paying for what you don't use," offering outstanding value for low-frequency users. Tech media have praised it for "solving the last mile of putting AI into practice," and users consistently applaud its model coverage, convenience, and powerful sharing features. The platform's benchmark lab regularly publishes AI model evaluations, demonstrating professionalism. The only shortcoming: as a relatively new platform, documentation completeness and customer support still have room to improve. Rating: 4/5 stars.
