## Fields

- [MaiDSR1](/reference/api/csharp/aspire.hosting.github.models/microsoft/fields.md#maidsr1) : [GitHubModel](/reference/api/csharp/aspire.hosting.github.models/githubmodel.md) `static` -- MAI-DS-R1 is a DeepSeek-R1 reasoning model that has been post-trained by the Microsoft AI team to fill in information gaps in the previous version of the model and improve its harm protections while maintaining R1 reasoning capabilities.
- [Phi4](/reference/api/csharp/aspire.hosting.github.models/microsoft/fields.md#phi4) : [GitHubModel](/reference/api/csharp/aspire.hosting.github.models/githubmodel.md) `static` -- Phi-4 14B, a highly capable model for low latency scenarios.
- [Phi4MiniInstruct](/reference/api/csharp/aspire.hosting.github.models/microsoft/fields.md#phi4miniinstruct) : [GitHubModel](/reference/api/csharp/aspire.hosting.github.models/githubmodel.md) `static` -- 3.8B parameters Small Language Model outperforming larger models in reasoning, math, coding, and function-calling
- [Phi4MiniReasoning](/reference/api/csharp/aspire.hosting.github.models/microsoft/fields.md#phi4minireasoning) : [GitHubModel](/reference/api/csharp/aspire.hosting.github.models/githubmodel.md) `static` -- Lightweight math reasoning model optimized for multi-step problem solving
- [Phi4MultimodalInstruct](/reference/api/csharp/aspire.hosting.github.models/microsoft/fields.md#phi4multimodalinstruct) : [GitHubModel](/reference/api/csharp/aspire.hosting.github.models/githubmodel.md) `static` -- First small multimodal model to have 3 modality inputs (text, audio, image), excelling in quality and efficiency
- [Phi4Reasoning](/reference/api/csharp/aspire.hosting.github.models/microsoft/fields.md#phi4reasoning) : [GitHubModel](/reference/api/csharp/aspire.hosting.github.models/githubmodel.md) `static` -- State-of-the-art open-weight reasoning model.
