✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Experiments show that ToolGrad models outperform those trained on expensive baseline datasets and proprietary LLMs.

C2weakest assumption

That the iterative process guided by textual gradients consistently produces valid and complex tool-use chains that generalize well to real user queries.

C3one line summary

ToolGrad inverts the standard tool-use dataset synthesis process by constructing valid tool chains first with textual gradients, producing a high-quality 500-example dataset with near-perfect validity and superior model performance.
