B.AI

What is B.AI?

B.AI is a large-scale model API aggregation platform built on blockchain technology, launched by Justin Sun. Its core LLM Service provides multi-model AI chat and API services, supporting login via Web3 wallets and centralized methods such as Google, and employing a dual-track settlement system of blockchain payments and fiat currency. B.AI grants AI Agents independent economic identities, enabling them to autonomously manage funds, purchase computing power, and execute Agent-to-Agent (A2A) settlements. It also provides a unified multi-model access, privacy-prioritized integration, and intelligent routing Agent API infrastructure.

B. AI’s main functions

Multi-model AI dialogue : Integrates multiple industry-leading large models, which users can switch freely according to their needs.
Complete AI API Service : Provides standardized APIs to support rapid access and integration within the B.AI framework.
Dual-track login system : Supports Web3 wallet signature login and centralized account login such as Google.
Flexible payment and settlement : Currently supports on-chain blockchain payments, fiat currency is supported in some scenarios, and third-party payment is continuously being expanded.
Agent economic identity : Agents can independently manage funds, procure computing resources, and complete A2A settlements.
Intelligent API Routing : A unified multi-model access point with structural price advantages and a privacy-first architecture.

How to use B.AI

Access Platform : Visit the B.AI official website https://b.ai/.
Log in to your account : Click “Log in” in the upper right corner, select “Web3 Wallet Connection Signing,” or log in using a centralized method such as Google.
Select Model : Click the current model name in the dialog interface to switch to the desired LLM from the list.
To start a conversation : Enter a prompt in the input box at the bottom and press Enter or click Send to initiate multiple rounds of interaction.
Top-up amount : Go to the Top up page of the Dashboard and select on-chain payment or fiat currency to top up your Credits.
API Integration : Consult the developer documentation to obtain the API Key and embed the LLM Service into your own Agent or application.

B. Key Information and Usage Requirements of AI

Product positioning : An AI Agent platform based on blockchain infrastructure, with the core module being LLM Service, aiming to provide AI Agents with “brain, passport, and economic system”.
Core capabilities : multi-model AI dialogue and API services, agent-independent economic identity (self-custodied funds + A2A settlement), dual-track login and payment.
Technical foundation : The blockchain underlying layer ensures security and settlement efficiency, intelligent routing allocates multi-model requests, and a privacy-first architecture protects interactive data.
User coverage : Simultaneously targeting Web3 native users (wallet login + on-chain payments) and mainstream users (Google login + fiat currency payments).

B.AI’s core advantages

Freedom of model selection : A single entry point aggregates multiple top-tier LLMs, balancing performance and cost as needed.
Low barrier to entry : It covers both native Web3 users and mainstream Internet users, without requiring mandatory encryption knowledge.
Agent Autonomous Economy : Pioneering Agent independent fund custody and A2A settlement capabilities to support the future Agent economic network.
Privacy-first design : AI interaction adopts a privacy-preserving architecture, and the authentication and access process is secure and controllable.
Payment flexibility : On-chain payments offer instant settlement, while fiat currency payments lower the barrier to entry for mainstream users.
