Hugging Face Bio’s Carbon-X, an open DNA-and-English model, is public with publisher-reported benchmark scores.

Hugging Face Bio released Carbon-X, a decoder-only model started from Qwen3-14B and trained jointly on DNA and natural-language text. It answers DNA questions in English, including variant-effect and next-base tasks, using a hybrid tokenizer that encodes DNA as 6-mers. The publisher reports 66.7% across five DNA benchmarks with thinking disabled, 27 points above Qwen3-14B and just under a cited GPT-6.1 Sol score, at far lower inference cost. The model card lists 14.8 billion parameters; MarkTechPost describes Carbon-X as a 14-billion-parameter model. Weights are released for local serving with Transformers v5 or later and vLLM.

Key facts
  • Architecture is 40 layers, hidden size 5120, and a 40,960-token context.
  • Mid-training used 302B tokens, then supervised fine-tuning and reinforcement learning.
  • Publisher reports 66.7% versus 67.5% for GPT-6.1 Sol at about 1/1,800 the cost.
  • Lab estimates analysing ClinVar’s 2.4 million uncertain variants would cost about $300.
  • It fits on one 80 GB GPU in bfloat16, according to the publisher.
