What is B.AI
B.AI is a large model API aggregation platform built on blockchain, launched by Justin Sun. Its core function, LLM Service, provides multi-model AI chat and API services, supports login via Web3 wallets and centralized methods such as Google, and adopts dual-track settlement with blockchain payments and fiat currency. B.AI gives AI Agents independent economic identities, enabling them to self-custody funds, procure computing power, and execute Agent-to-Agent (A2A) settlements, while also providing Agent API infrastructure with unified multi-model access, privacy-first integration, and intelligent routing.

Key information and usage requirements of B.AI
-
Product positioning: An AI Agent platform based on blockchain infrastructure, with LLM Service as its core module, aiming to provide AI Agents with a "brain, passport, and economic system".
-
Core capabilities: Multi-model AI chat and API services, independent Agent economic identity (self-custodied funds + A2A settlement), and dual-track login and payment.
-
Technical foundation: The blockchain foundation ensures security and settlement efficiency, intelligent routing distributes multi-model requests, and the privacy-first architecture protects interaction data.
-
User coverage: Serves both Web3-native users (wallet login + on-chain payment) and mainstream users (Google login + fiat payment).
B.AI's core advantages
-
Freedom of model choice: One entry point aggregates multiple top LLMs, balancing performance and cost on demand.
-
Low barrier to entry: Covers both Web3-native users and mainstream internet users, with no mandatory crypto knowledge.
-
Agent autonomous economy: Pioneering Agent independent fund custody and A2A settlement capabilities, supporting the future Agent economic network.
-
Privacy-first design: AI interactions adopt a privacy-preserving architecture, with authentication and access processes secure and controllable.
-
Payment flexibility: On-chain payments settle instantly, while fiat payments lower the barrier to entry for mainstream users.
