Dataset

FineDNA

Training corpus of the Carbon-X DNA language model for all three of its stages: mid-training on genomes, transcripts, biology text, English and instruction data, then supervised fine-tuning conversations and reinforcement-learning prompts.

No reviewed evaluations of this dataset are linked in this release.

Research readiness

0 of 4 readiness checks met. These checks assess whether the evidence supports a reproducible investigation; a source-checked score alone does not meet them.

Readiness describes the evidence in this release. Availability on your computer is checked separately when an investigation runs. Existing data exposure can prevent independent validation even when files are available.

Artifacts and reproduction

No verified artifact manifest is connected to this record yet. The gaps above identify what is needed before analysis can begin.

Dataset and evaluation context

A dataset supplies biological observations. The evaluation protocol defines how those observations are split, used and scored.

Evidence

Source checking verifies the cited claim or transcription. It does not establish independent reproduction.

Evidence table

Inspect claims, sources and review details

Trace each statement to its source and review. A context-only reference supports the record generally; it does not verify an individual field. Source checking does not reproduce an experiment.

One row per statement and cited source. Multiple citations are not independent evaluations. Shared locators are labelled explicitly.

Technical metadata and extraction receipts

Stable ID: finedna-20261101-data-finedna

areas: dna-genomes
contexts: research
reported name: FineDNA
version: Hugging Face commit e918c3649ffc614684d10e46e1eb5ba41170e7f9
repository: https://huggingface.co/datasets/HuggingFaceBio/FineDNA
access: Public download from Hugging Face; the mid-training configs total about 950 GB and are meant to be streamed.
species: Eukaryotes (fungi, protozoa, plants, invertebrates, mammals, other vertebrates) from GENERator; mRNA and prokaryote genomes (GTDB and IMG/PR) from OpenGenome2
population: Mid-training: 23 configs, 514.30B tokens, of which Carbon-X read 302B by weighted sampling (DNA 55%, biology text 15%, English 20%, instruction data 10%). SFT: 203,923 conversations (230.3M tokens) in eight domains, including 57,254 variant-effect prediction rows. RL: 98,433 verifiable prompts (61.1M tokens) in eight task groups, including bioreason (19,996), vepqa (7,426) and genomeqa (14,032) prompts.
split: Training data only. Biology-text mid-training configs carry a validation split held out to track loss; the SFT and RL configs are training rows in trainer order.
scope note: A training corpus, not an evaluation set: no result in this store is measured on it. It is recorded so that training overlap can be checked for evaluations of Carbon-X and of models trained on the same upstream data. mid_dna_mrna_splice holds 56.9 million OpenGenome2 mRNA sequences with splice and promoter context, with splice-junction markers removed.
reuse restrictions: Apache-2.0 for FineDNA; the mid-training configs come from GENERator, OpenGenome2, FineWeb-Edu, DCLM, FinePDFs-Edu, PubMed Central, bioRxiv, Biostars and Nemotron, which keep their own licences and terms.

review: method: source-hash-verification; automated-source-review; ai-assisted-source-review; reviewer: claude; reviewer note: Claude agent; no human review claimed. Extractor and reviewer were the same agent in the same session.; date: 2026-11-01; method note: Both cards re-read at their pinned commits with SHA-256 checked; build.py asserts each quoted count and statement against the card text.; note: Descriptive records only; no result.
