About

Trinity Large Thinking is a frontier open source reasoning model developed by Arcee AI, designed specifically for complex, multi-step problem solving and autonomous agent workflows that require long-horizon planning and tool use. Built on a sparse Mixture-of-Experts architecture with roughly 400 billion total parameters but only about 13 billion active per token, the model achieves high efficiency while maintaining strong reasoning performance across tasks such as mathematical problem solving, code generation, and multi-step analysis. It introduces extended chain-of-thought reasoning capabilities, allowing the model to generate intermediate “thinking traces” before producing final answers, which improves accuracy and reliability in complex scenarios. Trinity Large Thinking supports a very large context window of up to 262K tokens, enabling it to process long documents, maintain state across extended interactions, and operate effectively in continuous agent loops.

About

Trinity POS is school nutrition software for K-12 districts, charter networks, and child-nutrition operators running NSLP, School Breakfast, SFSP, CACFP, and CEP. Point of sale: a cashier app on tablet, phone, or web with serving lines, offline capability for weak Wi-Fi, duplicate-serve protection, and eligibility privacy built in - the cashier never sees whether a student is free, reduced, or paid (7 CFR 245.8). Eligibility: online and paper free/reduced applications in English, Spanish, and Vietnamese, income determinations, Direct Certification imports, letters, and verification sampling. Parent portal: families add funds online, set automatic top-ups and spending limits, and view balances and menus. Deposits settle to each school's own bank account. Claims: reimbursement claim worksheets built from recorded serves, with edit checks, export, and submission history. Trinity does not file with the state on your behalf.
