■ AI-SUMMARIZED FROM 1 SOURCE ▸ TIMELINE

An open-source CLI agent scored 65.2% on TerminalBench, surpassing Google's official Gemini-3-flash-preview result of 47.8% and the previous top closed-source model Junie CLI's 64.3%.

The developer behind the agent addressed concerns about benchmark integrity by confirming no cheating mechanisms were employed. The submission included no agent skill files or resource modifications, and was run in full compliance with leaderboard requirements. This result comes amid recent reports of deliberate cheating on TerminalBench 2.0, where some submissions have used unauthorized techniques to inflate scores. The developer's transparency about testing methodology underscores the importance of honest benchmarking practices in AI agent development. The open-source agent's performance suggests that publicly available models paired with effective prompt engineering can match or exceed proprietary alternatives on terminal-based task completion. The full benchmark details remain under review.
