Issue

There's a behavior where users can change the model mid-conversation and have it apply to future requests, but this functionality is undocumented and potentially unintended.

Context

A user reported being able to:

1. Go to New Chat
2. Change the model
3. Go back to an existing conversation
4. Have future requests in that conversation use the newly selected model

Philz42 indicated this behavior shouldn't work: "Um, that shouldn't work. Maybe it does but it shouldn't. You can change the database I guess…"

Notes

• This is currently an undocumented feature
• It may be a side effect rather than intended behavior
• Database changes may be involved
• Need to clarify whether this should be:
  • Explicitly supported and documented
  • Fixed/disabled as unintended behavior
