Carbon-500M GGUF

GGUF (bf16) conversion of HuggingFaceBio/Carbon-500M for use with llama.cpp.

Carbon is a hybrid DNA / English language model that switches between Qwen3-4B-Base byte-level BPE for natural text and fixed 6-mer chunking for DNA inside <dna>...</dna> tags.

Requires a recent llama.cpp

HybridDNATokenizer support was merged in ggml-org/llama.cpp#23410, so any build from master after that works:

git clone https://github.com/ggml-org/llama.cpp
cd llama.cpp && cmake -B build && cmake --build build -j

Usage

Download

hf download HuggingFaceBio/Carbon-500M-GGUF carbon-500m-bf16.gguf --local-dir .

Basic DNA completion

./build/bin/llama-completion -m carbon-500m-bf16.gguf \
    -p '<dna>ATGCGCTAGCTACGATCGATCGTAGCTAGCTAGCTAGCTACG' \
    -n 64 --temp 0 -no-cnv

As a draft model for speculative decoding

Carbon-500M shares the HybridDNA vocab with the larger models, so it makes an excellent draft model:

# 8B target + 500M draft -> ~2x speedup at temp=0
./build/bin/llama-speculative \
    -m  carbon-8b-bf16.gguf \
    -md carbon-500m-bf16.gguf \
    -p '<dna>ATGCGCTAGCTACGATCGATCGTAGCTAGCTAGCTAGCTACG' \
    -n 256 --temp 0
