A UC Berkeley study ran seven frontier models on SWE-bench Lite across multiple harnesses such as Pi, Codex and Cloud Code, and found that on newer, smarter models the choice of harness had no significant effect on scores.

UnverifiedSmall models below 7B must rely on few-shot examples, short prompts, a single task, and an explicit output format.63% similarUnverifiedThe instructor believes that the ranking of model strength is not fixed and the leaderboard will change over time, allowing for flexible switching between different periods.62% similarUnverifiedStandard Bayesian optimization acquisition functions (such as GP-UCB, EI, Thompson sampling) are almost all designed to minimize cumulative regret, and therefore naturally favor exploitation over exploration.62% similarUnverifiedThe developer lists seven project limitations, including the small sample, only one round of pressure, temperature 0.5, small local models, defenders being told the answer directly, scoring looking only at the final answer, and the Lambda quota wording not being precise enough.61% similarUnverifiedResearchers have found that fine-tuning only a small number of model parameters is sufficient to remove safety alignment (de-alignment attacks), and that certain jailbreak prompts can transfer across different models.61% similar
