GPT-6 Sol launches only in Codex and ChatGPT Work

An unfortunate trend: new AI models launch for agents first, while chat gets treated as an afterthought. Grok 4.6 arrived in Grok Build and Cursor, but was missing from the Grok website and app. Now GPT-6 Sol is available in Codex and ChatGPT Work, but you still can't select it in ChatGPT Chat. I like agents. I also want to open a chat and talk to the new model: ask questions, explore ideas, and see how it responds without giving it a task to complete. A model launch feels unfinished when you can't do that in the company's main chat product!
