Neptune
A metadata store for MLOps, helping data scientists log, organize, and compare their machine learning experiments and models.
TECHNICAL DEFINITION
Neptune.ai is a metadata store and experiment tracking platform for MLOps, designed to log, organize, compare, and share machine learning experiments, models, and datasets, facilitating reproducibility and collaboration in ML development.
BACKGROUND
OpenAI is an American artificial intelligence (AI) public benefit corporation headquartered in San Francisco. It develops proprietary generative AI models, particularly its GPT series of large language models (LLMs). Its release of ChatGPT in November 2022 has been credited with catalyzing the AI boom; as of 2026 ChatGPT is the fifth-most-visited website globally. OpenAI also releases Codex, an AI coding agent, and the GPT Image models. In April 2026, OpenAI closed a funding round with a post-money valuation of $852 billion.
