CHIMERA: Compact Synthetic Data for Generalizable LLM Reasoning

CHIMERA is a small (about 9,000 examples) but very carefully built synthetic dataset that teaches AI to solve hard problems step by step.

Composition-RL: Compose Your Verifiable Prompts for Reinforcement Learning of Large Language Models

Intermediate

Xin Xu, Clive Bai et al.Feb 12arXiv

This paper shows a simple way to turn many 'too-easy' questions into harder, still-checkable ones so that AI keeps learning instead of stalling.

Data Repetition Beats Data Scaling in Long-CoT Supervised Fine-Tuning

Intermediate

Dawid J. Kopiczko, Sagar Vaze et al.Feb 11arXiv

The paper shows that, when teaching a reasoning AI with step-by-step examples, repeating a small set many times can beat using a huge set only once.

Training LLMs for Divide-and-Conquer Reasoning Elevates Test-Time Scalability

Intermediate

Xiao Liang, Zhong-Zhi Li et al.Feb 2arXiv

The paper trains language models to solve hard problems by first breaking them into smaller parts and then solving those parts, instead of only thinking in one long chain.

Harder Is Better: Boosting Mathematical Reasoning via Difficulty-Aware GRPO and Multi-Aspect Question Reformulation

Intermediate

Yanqi Dai, Yuxiang Ji et al.Jan 28arXiv

This paper says that to make math-solving AIs smarter, we should train them more on the hardest questions they can almost solve.

Falcon-H1R: Pushing the Reasoning Frontiers with a Hybrid Model for Efficient Test-Time Scaling

Beginner

Falcon LLM Team, Iheb Chaabane et al.Jan 5arXiv

Falcon-H1R is a small (7B) AI model that thinks really well without needing giant computers.

Exploration vs Exploitation: Rethinking RLVR through Clipping, Entropy, and Spurious Reward

Intermediate

Peter Chen, Xiaopeng Li et al.Dec 18arXiv

The paper studies why two opposite-sounding tricks in RL for reasoning—adding random (spurious) rewards and reducing randomness (entropy)—can both seem to help large language models think better.
