Branching chats

Branch from any message

Pick a message and branch. Koshra starts a new thread from that point, with everything before it, and leaves the original untouched.

Try another model

Combine a branch with the model picker to see how a different model handles the same point in the conversation. Every reply shows its model, cost and time, so the comparison is plain.

Read about models and cost

Keep what works

Carry on in whichever thread worked better. Nothing is merged or overwritten for you.
