+</div>
+
+**GoLongRL-4B** achieves strong long-context performance at the 4B scale. Our framework combines the following:
+
+1. **Capability-Oriented Dataset (23K samples, 9 task types).** Guided by a taxonomy of long-context capabilities, the dataset covers precise retrieval, comprehension, exhaustive retrieval, numerical reasoning, structured extraction, structured matching, graded ranking, sequence ordering, and summarization. Each task is paired with its natural evaluation metric (EM, Accuracy, F1, math_verify, IoU, SubEM, NDCG, Pairwise, ROUGE-L) as the reward function.
+
+2. **TMN-Reweight.** To address optimization challenges from heterogeneous rewards, we propose TMN-Reweight, which combines task-level mean normalization for cross-task reward scale alignment with difficulty-adaptive weighting for more reliable advantage estimation. It provides a modest but consistent improvement over vanilla GRPO.
+
+3. **Full Open Release.** We publicly release the complete dataset, the four-phase construction pipeline, and all training code.
+
+### Key Results
+
+- Under the same vanilla GRPO setup, our dataset alone outperforms the closed-source QwenLong-L1.5 dataset.
+- TMN-Reweight further improves average performance to 63.0 at 4B scale, surpassing QwenLong-L1.5 with its specialized AEPO algorithm.
+- General capabilities (MMLU-Pro, AIME24/25, GPQA) are preserved or improved, with substantial gains on dialogue memory (LongMemEval +13.6) and agentic memory benchmarks.
+
+## 🔍 Evaluation
+
+Evaluation uses **QwenLong-Benchmarks**, covering three capability dimensions:
+
+| Dimension | Benchmarks |
+|-----------|-----------|
+| **Long-Context** | LongBench-V2, MRCR (≤128K / 128K–512K / 512K–1M), Frames, LongBench QA, DocMath, CorpusQA (≤128K / ≤1M) |
+| **General** | MMLU-Pro, AIME 2024/2025, GPQA-Diamond |
+| **Memory** | BFCL-V4 (memory subset), LongMemEval |
