Most .NET AI integrations stop at inference. LM-Kit.NET covers the full range of capabilities production applications actually need: agentic workflows with tool calling, planning, and memory; document intelligence with OCR and structured extraction; retrieval-augmented generation with built-in vector storage; multilingual speech-to-text; vision and multimodal understanding; text analysis with classification, NER, PII extraction, and sentiment; and text generation with translation, summarization, and constrained output. Ships in one NuGet package, runs in-process with no sidecar services, and works across all major hardware acceleration backends. Drop-in replacement for Semantic Kernel through its Microsoft.Extensions.AI compatibility layer. 29 Ratings Visit Website LTX LTX is an open foundation model for video, audio, and world simulation. You get full control over your AI: run LTX locally on your own hardware, fine tune it on your own IP, and generate video and audio as one unified output instead of stitching together separate tools. The latest model, LTX-2.5, is a 22B-parameter dual-stream diffusion transformer that generates native 4K video at up to 50fps, with synchronized audio and video produced in a single pass. Weights, code, and research are fully open, and independent benchmarking from Artificial Analysis ranks LTX among the top 3 AI video models globally. Access LTX three ways: download the open weights and run it yourself, license the model for on-premise deployment with enterprise support, or build on LTX Studio, the production suite for creative teams and studios. Teams at ElevenLabs, Asteria Film Co., Magnopus, and NVIDIA already build on LTX. LTX is production infrastructure for AI teams generating motion and physical environments inside their own pipelines, not a consumer app for one-off clips. 182 Ratings Visit Website Evertune Evertune is the Generative Engine Optimization (GEO) platform for enterprise brands that need to know -- and improve -- how AI models represent them. When buyers use ChatGPT, Gemini, Perplexity or AI Overviews to research a category, your brand either shows up confidently or it doesn't show up at all. Evertune closes the gap between knowing you have a visibility problem and solving it. We prompt across every major LLM at scale -- ChatGPT, Gemini, Claude, Perplexity, Meta AI, Copilot, DeepSeek, AI Overviews and AI Mode -- combining direct API access to foundational model knowledge, consumer app data and our 25M-person EverPanel of real internet users. That combination delivers statistically significant insights, not metrics that shift unpredictably from one query to the next. From there, Evertune translates data into action: identifying which pages on your site need optimization, generating content tailored to your brand voice and designed for AI visibility, surfacing the source U 1 Rating Visit Website Canditech Discover candidates’ real skills - not just their resumes - with Canditech’s candidate evaluation platform.
