OpenAI's latest flagship language model is GPT-3 (Generative Pre-trained Transformer 3). GPT-3 was introduced in 2020 and is a large-scale language model capable of performing a variety of natural language processing tasks.

Some key facts about GPT-3:

- It has 175 billion parameters, making it one of the largest language models ever created.
- It was trained on a massive amount of text data from the internet, giving it broad knowledge across many domains.
- GPT-3 can be used for tasks like text generation, question answering, summarization, translation, and more.
- It has shown impressive few-shot learning capabilities, meaning it can perform new tasks with just a handful of examples.
- Access to GPT-3 is controlled by OpenAI, and currently only available through their API to selected developers and researchers.

While GPT-3 is OpenAI's current flagship, the company is continuously working on improving and expanding their language model capabilities. However, they have not yet publicly released a successor to GPT-3 as their latest flagship model.
