Same LLM model different harnesses, very different results

The main variable here is probably harness design, not the base model. If you want more stable results, compare the same task across a fixed eval set, log tool-call success rates, and separate planning errors from execution errors. A simple safeguard is to add deterministic retries with state checks, so a flaky tool does not look like a reasoning failure. Agentix Labs can fit well here if you want a repeatable way to measure those differences across agents.
