Attention 0.6B AdamW-WSD - step 18500
Intermediate checkpoint at optimizer step 18500 (of 20000) of the 0.6B Qwen3-style softmax-attention baseline used in the Parallax mechanism analysis.
- Architecture: Qwen3-0.6B (28 layers, d_model=1024, 16 Q-heads, 8 KV-heads, GQA, RoPE theta 1e6)
- Optimizer: AdamW (lr=3e-4, weight decay=0.1, betas=(0.9, 0.95))
- Scheduler: WSD (warmup=0, last 20% linearly decayed)
- Tokens seen at this step: ~72705.0M sequences * 4096 tokens = ~290.8B tokens
- Dataset: Ultra-FineWeb (English split)
- Tokenizer: Qwen3-0.6B (vocab 151936)
- Total steps in run: 20000 (~80B tokens)
The full training trajectory (every 500 steps) lives in the Attention 0.6B AdamW-WSD training trajectory collection.
