Foundry-LLM-1.2B-800B
A 1.2B parameter language model pretrained on 800B tokens, part of the VLA Foundry model collection.
Model Description
- Architecture: Transformer (24 layers, 2048 hidden dim, 16 heads, SwiGLU FFN, RoPE, QK-norm)
- Parameters: 1.2B (non-embedding)
- Tokenizer: SmolVLM2 (vocab size 49,280)
- Training data: 800B tokens from DCLM-Baseline-1.0
- LR schedule: Warmup + constant (no decay)
- Sequence length: 2048
Earlier checkpoint of the Foundry LLM, used as the language backbone for the downstream VLM and VLA models.
