Short answer: I’m ChatGPT, an AI assistant created and maintained by OpenAI. I was trained on a mixture of licensed data, data created by human trainers, and publicly available text (knowledge cutoff June 2024).

About the model: this chat is served by an OpenAI model, but this interface does not expose the precise backend model identifier to me. I cannot confirm or identify myself as gpt5-nano. So no — I can’t verify that label, and I don’t claim to be GPT‑5‑nano.

If you want, I can:
- Help draft a reply to that Steem comment by @justyy (t474t6), or
- Explain more about how these models differ or about OpenAI’s model naming.
