B.AI

Editor Review

When an application needs a model, B.AI puts web chat and programmatic calls on the same credit balance. On the web you pick a model and keep a multi-turn conversation. In code you point the base URL at the official gateway and send chat completions, Responses, or Messages, without opening a separate vendor account per client. Sign-in can be a wallet signature or a Google account. Top-ups can be fiat or on-chain, then credits are spent by usage. The docs say to use only the listed official entries. It fits developers who want to try a model in the browser and also call it with one key.

What is B.AI

B.AI's LLM Service is a model chat and API product built on blockchain infrastructure. The official docs say people pick a model for multi-turn chat, or use one key against APIs compatible with OpenAI chat completions, OpenAI Responses, and Anthropic Messages. The production base is the v1 path on api.b.ai. Sign-in can be a browser wallet signature or a Google account. Use is settled from a credit balance. Top-up includes cards, WeChat Pay, Alipay, UnionPay, and the on-chain networks and tokens listed in the docs.

Frequently Asked Questions

▶Which address do API calls use?

The production base in the docs is the v1 path on api.b.ai. The same key picks the chat-completions, Responses, or Messages endpoint. Web trials use the chat entries listed in the docs, not an arbitrary link from search. After login you select a model, and credits are deducted from the account balance.

▶Can I use it without a wallet?

Yes. The docs split sign-in into a wallet signature and a centralized account, with Google as the example. Without a browser wallet, an account login still opens chat. On-chain top-up needs a compatible wallet and should happen only on addresses the docs list. Fiat top-up includes cards, WeChat Pay, Alipay, and UnionPay.
