Ant opens a 124B-parameter finance model

Ant Group open-sourced Ling-3.0-flash-Fin, a 124B-parameter mixture-of-experts model that activates 5.1B parameters per token and carries a 256K context window. Its model card positions it for source-grounded financial search, valuation models, spreadsheets, and long-horizon workflows, with FinFIRST released for evaluation. Builders working on research automation budgets should treat it as a specialized open-weight option to benchmark—not a substitute for professional review of investment conclusions.
