Episode 1 · Ant Releases Ling-3.0-flash-Fin: 124B Finance Model, Free API Month, Open Weights Next Week (2026-08-28, 5 posts)

Ant Group released Ling-3.0-flash-Fin, a finance-enhanced version of Ling-3.0-flash with 124B total and 5.1B active parameters, developed with financial institutions and domain experts. The API is free for one month on Nous Portal and via OpenRouter, and weights are slated for open-sourcing next week.

Confirmed

  • Specs: 124B total / 5.1B active parameters, MoE architecture, positioned as a finance-tuned Ling-3.0-flash
  • Capabilities: long-report retrieval, research, valuation modeling and report generation, carrying definitions, sources and calculations across research materials and workbooks to counter context drift; benchmarked on FinFIRST, FinCRAF and others
  • Availability: free one-month API on Nous Portal and OpenRouter; weights to be open-sourced next week

Unconfirmed

  • Real-world performance: @WarInspiron wants to see whether it reads long filings, extracts correct figures and compares companies without hallucinating; more user testing is needed
  • @DesignerMouse6109 argues the more interesting question is its "human review boundary" framing—where a finance agent should stop and hand assumptions back to humans—whose effectiveness remains to be seen

Why it matters

  • Finance is one of the domains where hallucinations cost most; a model tuned for long-filing context drift with promised open weights gives research and fintech teams a low-cost option, and the free month lowers the barrier to hands-on evaluation.
