Endpoint
GEThttps://llm.gedx402.com/v1/llm/nemotron-3-120b-a12bWhen to prefer
Choose this endpoint when you need a very large (120B parameter) NVIDIA Nemotron model for high-quality text generation, want to pay per-call in USDC without registering for an API key, and need to use crypto-native payment rails (Base, Polygon, Arbitrum, World, or Solana). Prefer over OpenAI or Anthropic hosted endpoints when API-key-free, blockchain-settled micropayments are required.
