# Decision models become selectable across hosted AI gateways

## Retrieval answer

Microsoft-Decision-1 is available in Foundry and Vercel AI Gateway, while LangSmith’s LLM Gateway supports the OpenAI Decisions API. Builders can route predefined-choice decisions through existing hosted gateway infrastructure. Before: Builders could use hosted gateways for model calls, but these items do not establish access there to the newly reported decision-model options and Decisions API. Enabling change: Microsoft-Decision-1 became available in

## Capability change

- Before: Builders could use hosted gateways for model calls, but these items do not establish access there to the newly reported decision-model options and Decisions API.
- Enabling change: Microsoft-Decision-1 became available in Microsoft Foundry and Vercel AI Gateway; LangSmith documented support for the OpenAI Decisions API.
- After: Builders can access decision-oriented models or APIs through multiple hosted AI gateway offerings.

Human consequence: Teams can evaluate and integrate decision calls through their existing model-access layer instead of relying only on generated text for such choices.

Bottleneck: The reports establish availability and gateway support, not interoperability, performance, or the quality of decisions on a particular task.

Buildability: B2. Verification: source-inspected. Related shift: [coding-agent-general-workbench](https://newruntime.com/shifts/coding-agent-general-workbench/).

The shift is concrete because separate reports place decision-oriented models or APIs in Foundry, Vercel AI Gateway, and LangSmith’s gateway. That offers builders more than a standalone model announcement: decision calls are appearing in existing hosted access layers.

A useful build is a small routing and evaluation layer that compares these decision options against the choices a workflow needs. The items do not show shared semantics or equivalent behavior across providers, so task fit and gateway compatibility remain to be verified.
