The authors say this phase can take more than 90% of runtime when models produce long chain-of-thought outputs. Existing tools also force a trade-off. TRL, DeepSpeed-Chat and ColossalChat are approachable but weak at inference… 2. **[OpenCoder: The Open Cookbook for Top-Tier Code Large Language Models](https://md.research.elamur.ai/free/en/papers/huang-2025-opencoder-open-cookbook-top-tier/)** *(2025 · 81 citations)* Most open code LLMs publish only their weights. Their training data, cleaning pipelines and training recipes stay hidden, which makes it hard for researchers to reproduce results or build strong baselines. OpenCoder addresses this gap. It is a code LLM family released with everything needed to rebuild it: weights… ## All works 3 works of theirs in our library, the most cited first; 2 with a page here, the others link their original until we summarise them. 1.
