A compact base model that has been fine-tuned with DAPO (Direct Alignment from Preference Optimization), giving it a particular flavor compared to standard Qwen3 4B base weights. As a base model variant, it sits closer to raw pretraining than instruction-tuned counterparts, meaning it responds differently to prompts and may require more careful prompting strategies.

Glossary

AlignmentThe process of training a model to behave safely and according to human values and preferences, which base models typically lack.Base ModelA pretrained model that completes text patterns but hasn't been trained to follow instructions, serving as a starting point for customization through fine-tuning.Fine-TunedA pre-trained model further trained on a smaller, task-specific dataset to improve performance on that task.Instruction-TunedA model fine-tuned on instruction-response pairs so it follows user prompts more reliably.Model VariantA modified version of a base model that changes its size, capabilities, or behavior while maintaining the same core architecture.OptimizationThe process of adjusting model parameters to minimize errors and improve performance.Preference OptimizationA training method that learns from pairwise comparisons between solutions rather than explicit reward signals.PretrainingThe initial training phase where a model learns general patterns from a large dataset before being adapted for specific downstream tasks.WeightsThe numerical parameters inside a neural network that determine how it processes input and generates output.
