QuantFactory/OpenThinker-7B-GGUF

This is quantized version of open-thoughts/OpenThinker-7B created using llama.cpp

Original Model Card

We have released a paper for OpenThoughts! See our paper here.

OpenThinker-7B

This model is a fine-tuned version of Qwen/Qwen2.5-7B-Instruct on the OpenThoughts-114k dataset dataset.

The dataset is derived by distilling DeepSeek-R1 using the data pipeline available on github. More info about the dataset can be found on the dataset card at OpenThoughts-114k dataset.

This model improves upon the Bespoke-Stratos-7B model, which used 17k examples (Bespoke-Stratos-17k dataset). The numbers reported in the table below are evaluated with our open-source tool Evalchemy.

We are fully open-source. Our model weights, datasets, data generation code, evaluation code, and training code are all publicly available.
