Solana MultiModal AI Agent is an open-source framework combining cutting-edge AI models—GPT for text, DALL·E for image, Whisper for audio transcription and synthesis, plus video generation—with the Solana blockchain. It provides a modular server architecture and RESTful API, enforcing per-request SOL payments on-chain. Developers configure their Solana wallet and OpenAI credentials, deploy the agent, then send multimodal requests via UI or API. Responses are delivered with associated transaction receipts. This design supports micropayments, auditability, and decentralized AI services, ideal for Web3 dApps and creative content platforms.
