summary: "An independent AI performance test has shifted the competitive landscape between proprietary and local models. GLM-5.3 Max beat GPT-5.6 Max and Sol to secure third place on the Terminal-Bench 4.0 leaderboard, outperforming the flagship offerings from OpenAI. The benchmark employs tasks designed to prevent \"benchmaxxing,\" a practice where developers optimize models specifically to game test scores. Some users called GPT-5.6 Sol the most overhyped model on the market following the results, which highlight a growing capability for open source intelligence to be run locally."
