jukofyork / DeepSeek-R1-0528-CODER-DRAFT-0.6B-v1.0

A 0.6B parameter draft (speculative decoding) model for use with deepseek-ai/DeepSeek-R1-0528 and deepseek-ai/DeepSeek-R1 .

NOTES :

• This is a draft model for the full-sized DeepSeek-R1-0528 / DeepSeek-R1 models and not the smaller "distilled" models!
• This version (unlike the previous jukofyork/DeepSeek-R1-DRAFT-0.5B-v1.0 ), was trained from jukofyork/DeepSeek-V3-0324-CODER-DRAFT-0.6B-v1.0 rather than from scratch.
• This version (unlike the previous jukofyork/DeepSeek-R1-DRAFT-0.5B-v1.0 ), doesn't trim the heads down from 14 to 12.

See jukofyork/DeepSeek-R1-0528-CODER-DRAFT-0.6B-v1.0-GGUF for the models in GGUF format.

How the model was created

1. The initial model was created from jukofyork/DeepSeek-V3-0324-CODER-DRAFT-0.6B-v1.0 using transplant-vocab :

python ./transplant_vocab.py \
        DeepSeek-V3-0324-CODER-DRAFT-0.6B \
        DeepSeek-R1-0528-BF16 \
        DeepSeek-R1-0528-CODER-DRAFT-0.6B-UNTRAINED

2. The following datasets were merged to create a fine-tuning dataset of ~2.5B tokens:

• open-thoughts/OpenThoughts-Unverified-173k
• https://huggingface.co/datasets/cognitivecomputations/dolphin-r1 (300k reasoning samples from DeepSeek-R1 only)

formatted using the proper DeepSeek-R1 Jinja template (ie: with <think> tags added around the reasoning, etc).

3. The model was then trained using qlora-pipe for 1 epoch with a batch size of 120 and a sequence length of 32k (~4M tokens per step):

resume_from_checkpoint = false

{
    "train_micro_batch_size_per_gpu": 1,
    "gradient_accumulation_steps": 20,
    "gradient_clipping": 1.0,
    "steps_per_print": 1
}

I used six RTX A6000 GPUs over three nodes and hence the 120 batch size ( 6 x 20 gradient accumulation steps = 120 ).
