K-quants are produced with --token-embedding-type Q8_0 --output-tensor-type Q8_0 so the sensitive embedding/output tensors stay at Q8_0 precision (important for this model's tight DNA-vs-text logit margins).

How to use

Click Use this model > llama.cpp on this page for a ready-made snippet. To install llama.cpp, follow llama.app or download a prebuilt binary from the releases page.

Carbon-8B is a base DNA model, not a chat model, so use text completion rather than the chat UI. Start the prompt with <dna>:

llama completion -hf HuggingFaceBio/Carbon-8B-GGUF:Q8_0 -p '<dna>ATGCGCTAGCTACGATCGATCGTAGCTAGCTAGCTAGCTACG' -n 128 --temp 0

llama serve -hf HuggingFaceBio/Carbon-8B-GGUF:Q8_0 serves the same model over HTTP; send raw prompts to its /completion endpoint.

  • Metadata conditioning: prefix the prompt with tags, e.g. <vertebrate_mammalian><protein_coding_region><dna>ATGCGCTAG.
  • Speculative decoding: add -hfd HuggingFaceBio/Carbon-500M-GGUF:Q8_0 to use Carbon-500M, which shares the vocabulary, as a draft model (about 2x faster at temperature 0).
  • Long context: for up to 65k tokens (about 393 kbp), add -c 65536 --rope-scaling yarn --rope-scale 4 --yarn-orig-ctx 32768.
  • Likelihoods: llama perplexity -hf HuggingFaceBio/Carbon-8B-GGUF:Q8_0 -f dna.txt gives corpus perplexity. For per-sequence log-likelihoods, use the Python score() from the source card.
