Product overview

Aspose.LLM for .NET is a library for integrating large language models (LLMs) into your .NET applications. You run models on your own infrastructure (on-premise or controlled cloud) and interact with them through a simple API: create an instance from a preset, start chat sessions, send messages, and optionally save or load conversation state.

Why Aspose.LLM?

• Preset-based setup — Use built-in presets for popular models (Qwen 2.5, Qwen 3, Gemma, Llama, Phi, and others) or customize parameters via PresetCoreBase.
• Chat sessions — Start a new chat with StartNewChatAsync, send messages with SendMessageAsync or SendMessageToSessionAsync, and keep multi-turn conversations.
• Session persistence — Save and load chat sessions to disk with SaveChatSession and LoadChatSession to resume conversations later.
• Optional multimodal input — Pass optional media (e.g. image bytes) with messages for vision-capable presets.
• Single instance — One AsposeLLMApi instance per process; create it with AsposeLLMApi.Create(preset).
• Licensing — Apply a license with License.SetLicense; check status with License.IsLicensed.
