Apache-2.0 code includes synthesis and evaluation pipelines. Scores depend on a pinned Gemma judge, and AI21 reports only small out-of-benchmark gains.</p><p><strong>Why read: </strong>LIFT-Bench publishes code and data for scoped long-form instruction following, while judge dependence limits generalization.</p><p>Recommendation: TRIAL</p><p>Sources: <a href="https://www.ai21.com/blog/lift-bench-blog/">AI21 LIFT-Bench announcement</a> · <a href="https://github.com/AI21Labs/lift-bench">AI21 LIFT-Bench repository</a> · <a href="https://arxiv.org/abs/2610.28819">LIFT-Bench paper</a></p>
