[FEAT]: Improve UX to let user know which LLM is actually going to be used

[kcalliauw]

What would you like to see?

As a user I tend to like to switch between LLMs often (this includes switching between Ollama models and OpenAI + Anthropic external models), and I currently find it very confusing / impossible to predict which of my LLMs are going to be chosen for a thread.

• LLM can be set in the Instance settings
• LLM can be set in the workspace settings
• LLM can be set in the workspace settings (but specific for agents)

As far as I can tell, if I change the chat agent in my workspace, the existing threads remain unaffected, which "feels" like a bug to me. I would expect (where possible) context to be carried over to the newly chosen LLM.

Ideally, like in various apps: ChatGPT or TypingMind, the LLM can be chosen inside the chat context/thread. For example, here are a few UX experiences I find to be very beneficial:

Just my 2 cents. Keep up the great work!
