Hugging Face Bio has released Carbon-X, an Apache 2.0 decoder-only model with 14.8B parameters that processes raw DNA and English in a single token stream and answers in natural language. Built on Qwen3-14B with a hybrid tokenizer adding 5,515 DNA tokens over 6-mers, it was trained in four stages and runs on one 80GB GPU or quantized GGUF builds. Hugging Face reports a 66.7% average across five DNA benchmarks, leading on BioReason Coding at 74.9% but weaker on GenomeQA splice-site questions at 2
Why it matters: It gives readers a concrete, openly licensed DNA model with weight-level access, deployment guidance and self-reported benchmarks for judging practical use.
