Build applications, test prompts, compare models, generate embeddings, analyze images, and create AI workflows using an OpenAI-compatible API. **No credit card. No subscription. No complicated setup.** Just create your free NVIDIA Developer account, generate your API key, and start building. --- ## FREE AI API ### Powerful models. Zero API cost. NVIDIA provides free access to a large catalog of artificial intelligence models through its NIM platform. You can use models from Meta, DeepSeek, Qwen, Mistral, NVIDIA, and other leading providers through a single API. The API is compatible with the OpenAI SDK, which means you can migrate an existing project by changing only the API address, model name, and key. ```python from openai import OpenAI client = OpenAI( base_url="https://integrate.api.nvidia.com/v1", api_key="nvapi-YOUR_KEY" ) response = client.chat.completions.create( model="meta/llama-3.1-70b-instruct", messages=[ { "role": "user", "content": "Create an AI business idea." } ] ) print(response.choices[0].message.content) ``` --- # What You Can Build With NVIDIA’s free API, you can create: * AI assistants * Chatbots * Content generators * Automation systems * AI agents * Search tools * RAG applications * Embedding systems * Image-analysis applications * Model comparison platforms * Internal business tools * Educational applications * Prototypes and MVPs You can experiment, learn, validate ideas, and build real applications without starting with a large API bill. --- # More Than 100 Models Available Choose the right model for each task. The catalog includes models for: * General conversation * Advanced reasoning * Programming * Long-context analysis * Multilingual content * Image understanding * Tool use * Embeddings
