epic: Jan's Default Assistant can be customized

[dan-homebrew]

Goal

• Jan has a default assistant (which is initially called Jan)
• User can customize Jan's default assistant (similar to how ChatGPT can be customized)
  • Name
  • Avatar
  • System prompt
  • Model (?)
• Changes to Jan's default assistant are global and persisted across Threads
• User can change thread-level settings in the Right Panel, but these are not persisted to Jan's default assistant

Tasklist

• [ ] Wireframes
• [ ] Assistant API spec
• [ ] UI changes
• [ ] Merge original changes from #3560
• [x] https://github.com/janhq/jan/issues/2894

Resources

Design

For Design, I would like us to move the Assistant out from the right panel (which is thread specific and not persisted)

• Can explore using the Left Ribbon
• Can pop up a screen that is a mix of ChatGPT's Custom GPT creation and Custom Instructions

User stories:

• User can set Avatar
• User can set Assistant name
• User can set System Prompt or Instruction

ChatGPT Custom Instructions

@imtuyethan I'm moving this to Sprint 21, as I don't think the team will be able to go to this this sprint. However, we should start working on wireframes (I will have more time to go through next week)

My Assistant page

• Similar to My Models page, My Assistant page allows users to customize the assistant's avatar, name & default instructions.
• Currently, there's only one assistant; it makes sense that we keep the assistant settings on the Settings page.

• Remove "Save Instructions for New Threads"

When there're multiple assistants

This is not a complete design, just bring up an idea first.

• We will have My Assistant page similar to My Models page where users manage all of their assistants as well as create new ones.

• User can see Assistant Menu next to Model Menu in threads
• They can switch assistants from there, as well as create new ones.
