Arcee

Arcee AI announced its Series B funding round led by Vista Equity Partners, Cambium Capital, and Emergence Capital, valuing the company at more than $1 billion, with participation from AI10 Ventures, Hitachi, IAG, M12, P7, and Wipro. The company will use the investment to accelerate development of its next generation o The round follows a year of rapid technical progress, culminating in Trinity Large, a 400-billion-parameter sparse mixture-of-experts model with 13 billion active parameters per token. Arcee developed its entire 2025 model lineup, including Trinity Large, for approximately $20 million, demonstrating a capital-efficient

On August 7, 2026, the U.S. Department of Energy launched the Genesis Open Models Initiative at genesisopenmodels.anl.gov through Argonne National Laboratory, and Arcee AI is the industry partner that co-developed the first model, Genesis-Science-1. The program produces open-weight foundation models built specifically The contribution portal defines two tracks: a foundation-stage data track with applications due August 14, 2026 and delivery by August 28, 2026, and a post-training data/environments track with applications due August 25, 2026 and delivery by September 14, 2026, each recurring roughly every three months. The applicatio

The U.S. Department of Energy, via the Genesis Open Models Initiative hosted at Argonne National Laboratory (genesisopenmodels.anl.gov), announced Genesis-Science-1 as the first open-weight model in a new class of foundation models designed to accelerate scientific discovery. Developed in partnership with Arcee — named DOE opened a contribution portal seeking open-weight models, pretraining contributions of domain-specific scientific data, fine-tuning efforts for domain-adapted versions of Genesis-Science-1, and evaluations; first-round applications are due August 14, 2026. The portal page describes a broad ecosystem model in which n
