OpenCodeReasoning-2
OpenCodeReasoning-2: A Large-scale Dataset for Reasoning in Code Generation and Critique
Dataset Description
OpenCodeReasoning-2 is the largest reasoning-based synthetic dataset to date for coding, comprising 1.4M samples in Python and 1.1M samples in C++ across 34,799 unique competitive programming questions.
OpenCodeReasoning-2 is designed for supervised fine-tuning (SFT) tasks of code completion and code critique.

Dataset Card for DRUID
Of the cmt-benchmark project.
Dataset Details
This dataset is a version of the DRUID dataset by Hagström et al. (2024). For this version, we have sampled 4,500 DRUID entries for which a "true target" (the factcheck verdict) and a "new target" (the stance of the context) could be found.
Dataset Structure
Thus far, we use two versions of the dataset: gpt2-xl and pythia-6.9b with corresponding validation (200 samples) and test splits… See the full description on the dataset page: https://huggingface.co/datasets/copenlu/cub-druid.cub-counterfact
Dataset Card for CounterFact
Of the cmt-benchmark project.
Dataset Details
This dataset is a version of the popular CounterFact dataset, originally proposed by Meng et al. (2022) and re-used in different variants by e.g. Ortu et al. (2024). For this version, the 899 CounterFact samples have been sampled based on the parametric memory of Pythia 6.9B, such that it contains samples for which the top model prediction without context is correct. We note that 546 samples in the… See the full description on the dataset page: https://huggingface.co/datasets/copenlu/cub-counterfact.cub-nq
Dataset Card for NQ
Of the cmt-benchmark project.
Dataset Details
This dataset is a version of the popular NQ dataset, originally proposed by Kwiatkowski et al. (2019). For this version, NQ samples have been obtained based on whether we can recover the gold passage from the original Wikipedia page and for which there is one short answer (less than 5 words in length). The context used in these samples is the correct gold context annotated by the original NQ annotators… See the full description on the dataset page: https://huggingface.co/datasets/copenlu/cub-nq.AXL-DATASET-1

que Cuban Spanish Conversational Sample (v0.3)
A synthetic sample that demonstrates the schema of the que conversational dataset for Cuban Spanish (es-CU). It accompanies the que white paper and shows prospective research partners what a que record looks like. This is synthetic demonstration data, not a collected corpus.
What this is
These records were constructed to the production schema to illustrate its shape. They stand in for data that has yet to be collected… See the full description on the dataset page: https://huggingface.co/datasets/que-app/cuban-spanish-sample.voice-agent-sft-v1
Voice-Agent SFT v1
Intended use: Downstream SFT fine-tuning for phone AI voice agents. NOT for pretraining.
This dataset targets models that must handle natural conversation + tool calling + function
calls (CRM lookups, web search, RAG DB queries) in a voice-agent context.
Built as a downstream specialization dataset for the
Cubix-AI diffusion-research project,
specifically for fine-tuning the Qwen3.5-4B-Base masked-diffusion LLM produced in Milestone 1.
