DOE launches Genesis-Science-1, its first open-weight science model

The U.S. Department of Energy, working with industry partner Arcee, launched the Genesis Open Models Initiative and unveiled Genesis-Science-1, DOE's first open-weight foundation model built for scientific research. The initiative sits inside DOE's broader Genesis Mission, which was launched by executive order in November 2025 with the stated goal of doubling the productivity and impact of American science and engineering within a decade. The Genesis Mission connects DOE's 17 national laboratories, leadership-class computing facilities and scientific data resources with partners across industry and academia, and is directed by DOE Under Secretary for Science Dario Gil.

DOE opened a contribution portal the same day, hosted at genesisopenmodels.anl.gov, inviting universities, national laboratories, companies, scientific nonprofits and research organizations to contribute open-weight models, pretraining data, fine-tuning work, evaluations and technical expertise. Applications for the first contribution window close August 14, 2026. The 2026 program runs two scheduled contribution tracks, and organizations may apply to both when their proposed contributions are distinct.

The portal is seeking material across several stages of model development: foundation-stage contributions such as scientific text, code, documentation and structured technical collections for pretraining or context extension; and post-training contributions such as expert demonstrations, annotated task examples, research software, datasets, workflow environments, reinforcement-learning tasks, held-out evaluations, scoring rubrics and verifiers. The program also wants scientists and engineers to review tasks, model behavior and completed artifacts, and it will take rolling inquiries from infrastructure providers about additional training or evaluation capacity. Applicants must identify the relevant track, describe the scientific work and its importance, state what material is ready, name the experts available to support it, and set out proposed terms of use. The public application form itself collects only descriptions and metadata; no scientific material changes hands during the application step, and each contributor specifies how its own material may be handled. Applications go through a DOE-governed review with input from academic, national laboratory and industry partners, passing through five gates: scientific fit, rights and handling, expert and evaluation readiness, technical integration, and final program selection. Contributors selected through this process will work with the researchers building and evaluating Genesis Open Models, get early evaluation access as the system develops, and be credited in the technical report and release materials.

Arcee is named as the first industry partner supporting the open-weights program and co-developed Genesis-Science-1. Arcee is a U.S. open-model lab that builds open-weight foundation models end to end, covering data preparation, architecture, pretraining, post-training, evaluation and deployment; its existing Trinity model family ranges from compact models meant for local use up to Trinity Large, a 400-billion-parameter sparse mixture-of-experts model. DOE describes the intent as giving researchers, national laboratories, industry partners and the open science community transparent, extensible AI models that can be adapted across scientific domains including materials discovery, energy systems, earth systems modeling, fusion, biology and high-energy physics.

Key facts

DOE and Arcee unveiled Genesis-Science-1, DOE's first open-weight model for scientific research, under the Genesis Mission launched by executive order in November 2025.
A DOE-hosted contribution portal opened the same day at genesisopenmodels.anl.gov; first-round applications close August 14, 2026.
The 2026 program runs two contribution tracks, and applications pass through five review gates: scientific fit, rights and handling, expert and evaluation readiness, technical integration, and final selection.
The Genesis Mission links DOE's 17 national laboratories and states a goal of doubling the productivity and impact of American science and engineering within a decade.
Arcee, the first industry partner, also builds the Trinity model family, topping out at Trinity Large, a 400-billion-parameter sparse mixture-of-experts model.

Why it matters

This is a U.S. government agency entering the open-weight model space directly, rather than only funding or regulating it. DOE is pairing a model release, Genesis-Science-1, with a standing contribution pipeline meant to pull in data, evaluations and fine-tuning work from universities, national labs, companies and nonprofits on an ongoing basis, not just a one-time launch.

Who it affects

Researchers at national laboratories and universities, companies with domain-specific scientific data or models to contribute, and infrastructure providers who can supply training or evaluation capacity are the direct audience for the portal. More broadly, the initiative targets scientific fields named in the announcement: materials discovery, energy systems, earth systems modeling, fusion, biology and high-energy physics.

How to use it

Organizations and researchers apply through the public form at genesisopenmodels.anl.gov by identifying a contribution track, describing the scientific work and why it matters, stating what material is ready, naming supporting experts, and proposing terms of use. The form collects only descriptions and metadata; no scientific material is transferred during the application itself, and each contributor sets the terms for how its own material may be handled later. The first-round deadline is August 14, 2026.

How solid is it

The announcement comes from DOE and Arcee directly, tied to a named executive order (November 2025) and a named program lead, DOE Under Secretary for Science Dario Gil. It states a concrete deadline and a five-gate review process. It does not disclose a release date for Genesis-Science-1 itself, pricing or licensing terms, the model's parameter count, or the identities of the 17 national laboratories or the two 2026 contribution tracks beyond their existence.

Risks and caveats

The application process is a solicitation for future contributions, not a finished product launch: what Genesis-Science-1 can currently do, how it will be licensed, and which organizations besides Arcee will participate are not specified in the announcement. Whether the five-gate DOE review process moves quickly enough to keep pace with a fast-moving field, and whether contributors are satisfied with the terms they set for their own material, are both open questions the announcement does not address.
