LingDT-Decision-1.0
By Ant Digital Technologies (蚂蚁数科) · Released 22 Oct 2026
Ant Digital Technologies' System One model for choosing answers to business questions, including native multi-select and decisions ordered by dependencies. IT之家 reported its 22 Oct 2026 launch in 4B and 27B versions for customer service, risk and finance. Ant's current DTMaaS listing describes the lingdt-decision-1.0 endpoint as a 4B test model.
Facts
- Sizes
- 4B and 27B announced, per IT之家; the current DTMaaS endpoint identifies itself as 4B
- Try it
- Open the DTMaaS model page and its API guide. Use an API key with POST maas-api.antdigital.com/v1/systemone and model lingdt-decision-1.0; send state, questions and optional DAG dependencies
- Limits
- Ant lists 32 questions per request, 255 options, DAG depth 3 and a default 60 requests per minute. Its English and Chinese descriptions disagree on whether the 16K context limit applies per question or per request.
- Price

- Jev and Microsoft-Decision-1 are hosted alternatives, each listed at $0.042 per million input tokens. LingDT's free-trial price covers a 4B test endpoint; these rates do not compare accuracy
