Kilo Code v7.5.6 lets you pick a separate, cheaper model just for compaction.

Compaction is a summarization job that rarely needs the frontier model you're paying for, and until now it silently ran on whatever you'd selected. The same release adds a searchable @ picker for referencing other Agent Manager worktrees, sharing paths, branches and session IDs without attaching diffs or chat history, and /review worktree covering committed and uncommitted changes. The parallel JetBrains v7.1.1 build fixes compaction recovery replaying requests, looping, or dropping pending tool progress, and fixes subagents returning empty task responses instead of real results. A subagent silently returning nothing is the worst failure mode in a multi-agent run, because the orchestrator treats it as a completed step. (GitHub)
