## 1.3 Overall training data size and characteristics

### 1.3.1 Size of dataset and characteristics

**1.3.1.A Text training data size:** 1 billion to 10 trillion tokens

**1.3.1.B Text training data content:** The training data for Phi-4-mini-reasoning consists exclusively of synthetic mathematical content generated by a stronger and more advanced reasoning model, Deepseek-R1. The objective is to distill knowledge from this model. This synthetic dataset comprises over one million diverse math problems spanning multiple levels of difficulty (from middle school to Ph.D. level). For each problem in the synthetic dataset, eight distinct solutions (rollouts) were sampled, and only those verified as correct were retained.

**1.3.1.C Image training data size:** Not applicable. Images are not part of the training data

**1.3.1.D Image training data content:** Not applicable

**1.3.1.E Audio training data size:** Not applicable. Audio is not part of the training data

**1.3.1.F Audio training data content:** Not applicable

**1.3.1.G Video training data size:** Not applicable. Videos are not part of the training data

**1.3.1.H Video training data content:** Not applicable

**1.3.1.I Other training data size:** Not applicable

**1.3.1.J Other training data content:** Not applicable

**1.3.2 Latest date of data acquisition/collection for model training:** February 2025

**1.3.3 Is data collection ongoing to update the model with new data collection after deployment?** No

**1.3.4 Date the training dataset was first used to train the model:** February 2025

**1.3.5 Rationale or purpose of data selection:** Datasets consist of synthetic mathematical problems and verified solutions generated by a stronger reasoning model to distill high-quality reasoning patterns and improve math problem-solving performance across difficulty levels
