Compare
Give the same task to two or three agents or models. Each works in its own worktree. You read the attempts and keep one.
Compare needs a git project, because each attempt gets its own worktree. If the folder isn't a repository yet, run git init in it first.
Run a Compare
Choose Compare
In the composer, click + and choose Compare.
Pick two or three agents or models
You can compare different agents, or two models of the same agent. The picker asks for at least two.
Describe the task and press Enter
The attempts run side by side, each on its own branch.
Keep one
When they finish, the card says Pick the attempt to keep. Open each attempt to read its work, then choose Keep this on the one you want. The others are marked Not kept and discarded. Nothing merges until you choose.
When to use it
- A tricky bug where you'd like more than one idea.
- Seeing how two models handle your codebase before you pick a default.
- A change where you care about the approach, not just the result.
Compare runs every attempt in full, so it uses capacity on each agent you pick.
Not in the beta yet. ThreadGrid doesn't pick the winner for you. Running the same tests on each attempt and choosing automatically is planned.
