An unbiased developer launched LLM402.ai on March twenty fifth. It is a service that permits you to browse synthetic intelligence (AI) fashions by paying completely in Bitcoin (BTC) through the Lightning Community (LN).
No account, electronic mail, or API key required. The one requirement is that you simply pay a Lightning invoice per question. In response to the developer’s publication, the service is operational as of at the moment.
amongst them, 32 fashions By AI accessible DeepSeek-R1, Llama (varied variations), Qwen, Mistral, and extra, all of which might be accessed through: endpoint Suitable with OpenAI and Ollama codecs, essentially the most used requirements.
Charges for every session Dynamic and charged per request (pay per request). This primarily depends upon the mannequin chosen, the variety of enter tokens (textual content despatched in prompts and contexts), and the utmost output tokens configured (max_tokens). That value is transformed to SATOSHI utilizing the present value of Bitcoin.
As such, the worth of the greenback tends to be very secure, however the actual quantity of satsis depends upon the BTC value on the time. In response to the creators, the most cost effective session is about 10 satoshis, or the equal of cents on the present greenback.
How does LLM402.ai work?
The LLM402.ai service makes use of the L402 protocol, an ordinary created by Lightning Labs, which mixes the HTTP code 402 (“Cost Required”) with a Lightning bill and an authentication token known as .macarons‘, show your cost on LLM402.ai.
AI brokers utilizing LLM402.ai ship requests to this method and obtain Lightning invoices together with their tokens. macarons, Pay your invoice and resubmit your request with proof of cost.
This take a look at causes the service to offer a response for the mannequin. There isn’t any prior registration or id verification, and cost serves as the one authentication data.
This service is particularly designed for autonomous AI brokers, applications that function alone with out a human approving every motion.
For its makes use of, the writer signifies that LLM402.ai is suitable with lnget. It is a Lightning Labs instrument that automates all the L402 circulate to find, pay, and resubmit requests with out human intervention.
The service can also be listed within the 402 Index, a listing launched on March 22 this yr. Over 15,000 endpoint Variety of paid APIs for AI brokersmakes it simpler for different brokers to mechanically uncover you.
Bitcoin Lightning as AI Infrastructure: Background
As reported by CriptoNoticias, the launch of LLM402.ai comes at a time when AI brokers and Bitcoin Lightning micropayments are converging.
On January thirty first, the Lightning Allow workforce launched an open supply instrument that enables AI brokers to make funds in Lightning through the Nostr Pockets Join protocol. This limits programmable spending limits and funds to BOLT11 invoices, that are normal Lightning codecs with recipient signatures and glued quantities.
This instrument can also be constructed on L402 and targets the identical mannequin. Brokers who autonomously pay for digital companiesthere isn’t any human intervention in every transaction.
LLM402.ai differs from the Lightning Allow equipment and Lightning Labs L402 protocol in that LLM402.ai just isn’t a instrument or technical specification for constructing brokers, however fairly a A service that enables AI brokers to question language fashionspay with Satoshis and obtain a response with out a single line of further configuration.
Whereas Lightning Allow and Lightning Labs constructed the infrastructure, LLM402.ai makes use of it to ship synthetic intelligence as a commodity paid for with microtransactions. Every question is a whole Bitcoin transaction and is settled in seconds, with none banks, accounts or intermediaries.
