# Why Polygon StarLLM uses Polygon PoS as a low-cost, developer-friendly settlement layer for AI inference payments. Polygon is suitable for AI inference credit settlement because it provides low transaction costs, fast finality, deep DeFi and NFT infrastructure, and a mature ecosystem of wallets, developer tools, and on-chain services. For StarLLM, Polygon is not only a token deployment target. It is the settlement layer that connects real AI inference consumption with programmable on-chain credits. Through this integration, Polygon developers can: * Top up AI inference balance using Polygon-based assets * Use STAR credits for real OpenAI-compatible model calls * Build AI agents that pay for inference through wallet-based flows * Integrate StarLLM into dApps, wallets, games, and agent frameworks * Verify payment and deposit records on Polygonscan --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
