Release notes: https://www.mef-llm-studio.com/en/changelog/#app-0-2-0 . Website updates are listed separately on that page. Education Education::Teaching & Training Tools Windows 10 20H1 build 19041 or later, or Windows 11, x64. A compatible NVIDIA GPU is required for GPU language-model training. Supported linked models may use optional CPU inference; Vision device support and memory requirements depend on the model. Internet access is needed for optional runtime/model downloads; allow at least 10 GiB for environment and caches. Microsoft WebView2 Runtime is required for the Explorers. 83975984 82008 80.09 N language model,LLM,education,Brain Explorer,Wiki,Explain,Vision,diffusion,tokenizer,training,fine-tuning,sampling,PyTorch,Windows Learn how language models work locally. Explore LLMs and image generation in an educational Windows desktop app. Educational Windows app for learning how language and image models work. Explore token-by-token generation in Brain Explorer, look up concepts in Wiki, and follow image denoising in Vision Explorer. Local experiments, no scripting. M.E.F LLM Studio connects learning chapters and local experiments in a Windows desktop app. Train small language models, compare checkpoints, explore token-by-token generation in the 2D Brain Explorer, and read Wiki explanations beside the interface. Generate images locally and inspect denoising, feature maps and selected cross-attention in Vision Explorer. Fine-tuning includes SFT, DPO and ORPO; supported local Llama/Qwen2 models can be linked. M.E.F LLM Studio is a Windows desktop learning program for people who want to understand how language models work by trying the steps themselves. It is not a production model-training system. The app places short learning chapters and a multilingual Wiki beside local experiments. Turn text into tokens, train a small decoder-only model, follow Loss and checkpoints, and compare generation settings in Sampling or Chat. Brain Explorer shows recorded token-by-token generation in 2D, with playback, token lanes and A/B inputs. Explain describes visible terms; Visual Explorer opens the underlying calculations. Fine-tuning introduces SFT, DPO and ORPO. Supported local Llama and Qwen2 Safetensors models can be linked without copying their weights and run with an explicit CPU or supported NVIDIA GPU profile. Manual A/B comparison keeps the two outputs separate and does not declare a winner. Vision generates images locally and opens their denoising recordings in Vision Explorer. Inspect state before, noise prediction and state after, numerical feature maps and one selected cross-attention site. Train a small 32 x 32 pixel learning model on image-caption pairs or compare small captioning training runs. Runtime, model and dataset downloads require confirmation. Toerken points to the next useful step; working drafts can be restored locally after a restart. Version 0.2.0 is an experimental Alpha for non-commercial evaluation, not production or safety-critical use. Language-model GPU training requires a compatible NVIDIA GPU. Vision device support and memory needs depend on the selected model. Keep independent backups. https://www.mef-llm-studio.com/en/ https://www.mef-llm-studio.com/images/app-learn.en-dark.png https://www.mef-llm-studio.com/favicon.ico https://www.mef-llm-studio.com/pad.xml https://www.mef-llm-studio.com/downloads/MEF-LLM-Studio-0.2.0-setup.exe Software catalog operators may list M.E.F LLM Studio and link to the publisher-hosted installer.
