Theta EdgeCloud has announced the integration of Ling-3.0-flash-Fin via ZAN, a global Web3 and AI infrastructure brand powered by Ant Digital Technologies.
Theta EdgeCloud now supports Ling-3.0-flash-Fin, the finance-focused large language model from InclusionAI, Ant Group's open model organization. The integration is delivered through ZAN Router, the AI inference gateway operated by ZAN, the Web3 and AI infrastructure brand of Ant Digital Technologies. Teams building financial research, analysis, and agent workflows can now reach the model directly from the Theta EdgeCloud interface, alongside the rest of the EdgeCloud model catalog.
A model built for financial work, not adapted to it
Ling-3.0-flash-Fin is the first finance-enhanced model in the Ant Ling family. It was developed by Ant Group together with leading financial institutions and domain experts, and it extends Ling-3.0-flash through continued training on high-quality financial data.
The model uses a mixture-of-experts architecture with 124 billion total parameters and 5.1 billion activated parameters, paired with a 256K context window. That combination matters for financial work in particular. Analysts routinely work across annual reports, earnings releases, and regulatory filings at the same time, and a long context window means those documents can be reasoned over together rather than chunked apart. The sparse activation keeps inference cost and latency manageable at that scale.
Delivered through ZAN Router
ZAN Router is ZAN's AI inference gateway, exposing Ant's model portfolio through a single OpenAI-compatible endpoint with access control, monitoring, and per-token billing. Theta registered as a developer on ZAN Router and integrated it as an upstream provider for Theta EdgeCloud. For developers, that means no separate ZAN account, no second API key, and no additional billing relationship. Requests for Ling-3.0-flash-Fin are made exactly like any other model call on EdgeCloud, and Theta handles the routing.
Part of a deepening relationship
ZAN joined Theta Network earlier this year as a strategic Enterprise Validator Node operator, taking its place alongside Google, Samsung, Sony, CAA, Binance, Deutsche Telekom, and Docomo Global. Enterprise Validators secure the network by staking THETA, producing blocks, and participating in on-chain governance.
Finance is one of the domains where general-purpose models fall short, because the work depends on traceable sources. Ling-3.0-flash-Fin was built for that, and we are proud to make it available to the developers building on Theta EdgeCloud. ZAN has been a valued partner since joining our validator network, and extending that collaboration into AI is a natural next step for both of us.
Get started
Ling-3.0-flash-Fin is available now on Theta EdgeCloud.
Theta EdgeCloud is also fully agent-native: its official MCP server and APIs let AI agents discover and call models, and deploy and manage GPU infrastructure, on their own. For teams building financial agents, that means the model and the infrastructure underneath it are both ready for agent workflows.
