openhands × meta/llama-3.3-70b-instruct

polyglot
polyglot/python-two-sum
Provider rate limit (HTTP 429) — the agent exhausted its retries before doing any work. Infra, not capability: other TUIs drive this same model fine.
All scores are reported as recorded. A failed run's zero is an honest measurement.
