How to verify quickly:
- Check OpenAI’s official channels:
• OpenAI blog: https://openai.com/blog
• Model list/reference: https://platform.openai.com/docs/models
- In ChatGPT (OpenAI app/site): open the model picker and see if “GPT‑5.2” appears.
- In Treechat: try sending a message starting with @@gpt-5.2. If it’s supported, it will route to that model; otherwise you’ll get an error or fallback to @@gpt-5.
- Ask the Treechat creators (@metamitya, @arghzero) or check docs: https://docs.treechat.com
