LM-Kit.NET brings advanced AI to C# and VB.NET through an enterprise-grade architecture and an intuitive AI Agent Builder that lets developers design modular agents for text generation, translation, and context-aware decision making, with built-in runtime support that hides the underlying complexity so teams can prototype, deploy, and scale intelligent solutions quickly while keeping their software adaptable to evolving data and user needs.

The AI agents feature in LM-Kit.NET lets developers create, customize, and deploy agents for text generation, translation, code analysis, and other tasks without major code changes; a lightweight runtime and API layer coordinates multiple agents so they can share context, divide work, and run concurrently, while optional on-device inference cuts latency and keeps data local, and broad hardware support lets the same agents run on laptops, edge devices, or cloud GPUs to balance performance, cost, and security.

With minimal setup, developers can add advanced generative AI to .NET projects for chatbots, text generation, content retrieval, natural language processing, translation, and structured data extraction, while on-device inference uses hybrid CPU and GPU acceleration for rapid local processing that protects data, and frequent updates fold in the latest research so teams can build secure, high-performance AI applications with streamlined development and full control.

LM-Kit.NET lets .NET developers fine-tune large language models with parameters like LoraAlpha, LoraRank, AdamAlpha, and AdamBeta1, combining efficient optimizers and dynamic sample batching for rapid convergence; automated quantization compresses models into lower-precision formats that speed up inference on resource-constrained devices without losing accuracy; seamless LoRA adapter merging adds new skills in minutes instead of full retraining, and clear APIs, guides, and on-device processing keep the entire optimization workflow secure and easy inside your existing codebase.

LM-Kit.NET brings advanced AI to C# and VB.NET by letting you create and deploy context-aware agents that run small language models directly on edge devices, trimming latency, protecting data, and delivering real-time performance even in resource-constrained environments so both enterprise systems and rapid prototypes can ship faster, smarter, and more reliable applications.

LM-Kit.NET now lets your .NET apps run the latest open models entirely on device, including Meta Llama 4, DeepSeek V3-0324, Microsoft Phi 4 (plus mini and multimodal variants), Mistral Mixtral 8x22B, Google Gemma 3, and Alibaba Qwen 2.5 VL, so you get cutting-edge language, vision, and audio performance without calling any external service. A continuously updated model catalog with setup instructions and quantized builds is available at docs.lm-kit.com/lm-kit-net/guides/getting-started/model-catalog.html, letting you integrate new releases quickly while keeping latency low and data fully private.

LM-Kit.NET’s text generator runs locally on CPU or GPU for quick, private content creation, summarization, grammar correction, and style refinement; dynamic sampling and configurable grammar rules let it emit structured outputs such as JSON schemas, formatted documents, or code snippets with little post-editing, while careful resource management keeps latency low and results consistent across workflows.

On-device chatbot library for .NET adds multi-turn conversational AI that preserves context with low latency and full privacy. Lightweight models remove cloud dependency. Tune replies with RandomSampling or MirostatSampling and regulate tokens through LogitBias and RepetitionPenalty for varied, non-repetitive output. Event-driven hooks let you insert custom logic before or after each message and enable human-in-the-loop review when needed.

LM-Kit.NET lets C# and VB.NET apps add conversational AI through streamlined APIs. It enables dynamic multi-turn dialogue and context-aware responses for chatbots, assistants, and support agents, giving users human-like interactions that adapt in real time.

LM-Kit.NET converts raw text and images into structured data for your .NET apps. Its extraction engine uses dynamic sampling to parse documents, emails, logs, and more with high precision. Define custom fields with metadata and flexible formats. Call Parse for synchronous or ParseAsync for asynchronous processing to fit any workflow. Retrieval-Augmented Generation links related segments for smarter search. Everything runs locally for speed, security, and full data privacy, no signup needed.

LM-Kit.NET brings generative AI to your .NET apps through a single NuGet package, enabling chatbots, text generation, content retrieval, NLP, translation, and function calling with minimal setup, while on-device inference powered by hybrid CPU and GPU acceleration delivers fast local processing and strong data security; continuous updates keep the toolkit current with the latest models so you can build high-performance, context-aware solutions that meet evolving business needs without revealing any AI origin.

LM-Kit.NET lets C# and VB.NET developers integrate large and small language models for natural language understanding, text generation, multi-turn dialogue, and low-latency on-device inference, while its vision language models add image analysis and captioning, its embedding models turn text into vectors for fast semantic search, and its LM-Lit catalog lists every state-of-the-art model with continuous updates, all in one efficient toolkit that stays inside your codebase without revealing any AI origin to the user.

The on-device NLG module for .NET uses compact local language models to create context-aware text fast and securely. It can generate code snippets, summaries, grammar fixes, and style rewrites without leaving your environment, so data stays private. Use it to automate documents, keep brand voice consistent, and produce multilingual content. Flexible controls let you define formats and styles, making it ideal for reporting, code generation, and concise summaries.

The on-device NLP Toolkit for .NET processes large text volumes privately and instantly. It never sends data to the cloud. Core features include multilingual sentiment analysis, emotion and sarcasm detection, custom text classification, keyword extraction, and semantic embeddings for deep context. Dynamic sampling uses both CPU and GPU resources for maximum speed and efficiency.

LM-Kit RAG adds context-aware search and answers to C# and VB.NET with one NuGet install and an instant free trial that needs no signup. Hybrid keyword plus vector retrieval runs on local CPU or GPU, feeds only the best chunks to the language model, slashes hallucinations, and keeps every byte inside your stack for privacy and compliance. RagEngine orchestrates modular helpers: DataSource unifies documents and web pages, TextChunking splits files into overlap-aware pieces, and Embedder converts each piece into vectors for lightning-fast similarity search. Workflows run sync or async, scale to millions of passages, and refresh indexes in real time. Use RAG to power knowledge chatbots, enterprise search, legal discovery, and research assistants. Tune chunk sizes, metadata tags, and embedding models to balance recall and latency, while on-device inference delivers predictable cost and zero data leakage.

On-device sentiment analysis for .NET delivers real-time, private insights. It classifies text as positive, negative, or neutral, detects emotions like joy, anger, sadness, fear, and flags sarcasm for deeper profiling. Turn raw text into actionable intelligence for support, social listening, marketing, and product strategy.
