About
NVIDIA NIM packages popular open models as ready-to-call APIs, and the free developer tier puts over 120 of them behind a single key. Chat models, embeddings, reranking, vision, and even audio and image generation, all OpenAI-compatible, so you stop juggling five providers and five key formats. The free tier runs about 40 requests per minute with no credit card, just phone verification at signup. When your agent needs a different model for a different subtask, you change one string instead of integrating a new provider.
