OpenAI is the AI research and deployment company founded in San Francisco in 2015. It ships the GPT series of large language models, ChatGPT (its consumer product), DALL-E (image generation), Whisper (speech-to-text), and Sora (video generation).
OpenAI's API is the most widely used commercial LLM platform. In 2026 it ships GPT-5 for general use, o-series reasoning models for complex tasks, and text-embedding-3 for embeddings. Major competitors: Anthropic (Claude), Google (Gemini), Meta (Llama), Mistral.
Nagro Solutions integrates OpenAI's API in production RAG systems, agents, and content generation pipelines — chosen based on quality-per-dollar for the specific use case rather than provider loyalty.
