Qwen3-4B Baseline (64k, 750 steps)
This model is Qwen3-4B trained with standard training (no TTT) on 64k context length for 750 training steps. This serves as the baseline for comparison with the In-Place TTT version.
🎯 Model Overview
- Base Model: Qwen3-4B (Qwen2.5-4B architecture)
- Training Method: Standard (no Test-Time Training)
- Context Length: 64k tokens
- Training Steps: 750
- Model Size: 8.3GB
- Format: HuggingFace Transformers (safetensors)
- Training Date: May 13, 2026
📊 Purpose
This is the baseline model for the In-Place TTT research project at 64k context length. It uses the same:
- Base architecture (Qwen3-4B)
- Training data (ProLong 64k)
- Hyperparameters
The only difference is that it does not use In-Place Test-Time Training.
🔬 Comparison
Compare this baseline with the TTT version to see the impact of In-Place TTT:
| Model | Type | Context | Steps |
|---|---|---|---|
| This Model | Baseline | 64k | 750 |
| 64k TTT | In-Place TTT | 64k | 1250 |
