      "content_text": "The Wiki can now be read on the website. The app remains at Alpha 0.2.0; Wiki content is maintained independently.\n\n- 117 topics in DE/EN/RO from the same content source as the app Wiki, with an independent Wiki revision and official references for the new tooling basics.\n\n- Explain opens short explanations beside the clicked term, with subtle highlighting, hover hints and keyboard support.\n\n- More compact search and topic filters; focus outlines appear for keyboard navigation only.\n\n- Corrections and new topics can be submitted privately for editorial review after explicit consent. Unreviewed suggestions are deleted after 90 days; no automatic publication.\n\n- CPU options and limits, installer signing and the developer’s background are explained more visibly.\n\n- Demo Explorer replays a supplied Qwen recording with the same Brain Explorer interface as the app: generation, A/B, input-pass inspection, Explain and a guided tour without running a model on the webserver.\n\n- The Web view offers approved examples only; saving and opening local files remain app features. The current demo recording does not yet contain additional Lab results.\n\n- A compact header avoids orphaned navigation links, uses a collapsible menu at narrower widths and shortens navigation labels to Download and Demo Explorer.\n\n- Three equal starting paths directly below the introduction lead to the Web Wiki with Explain, your own model in the Windows app, and Demo Explorer with an additional Vision guide. The personal origin story follows afterwards.\n\n- Wiki suggestions can only be sent after checking the permission box. Explain also recognises tokenizer without marking ordinary step-by-step wording twice as a training term.",

      "content_text": "Alpha 0.2.0 adds a 2D Brain Explorer, a multilingual Wiki and learning tools for image generation and image captioning.\n\n- A reorganized learning pipeline separates source text, tokenization and dataset preparation; the published GPT-2 vocabulary is available as an optional download.\n\n- A multilingual Wiki adds search, related topics and concept explanations in Learn and supported app text, including recognition of word forms and plurals.\n\n- A new 2D Brain Explorer follows context through attention and MLP to probabilities, sampling and appending the next token.\n\n- Recorded generation supports playback, pause and step-by-step inspection. A/B views compare two inputs through the same model.\n\n- Token lanes distinguish input from generated text. Inspect attention, individual heads, vector slices and, for supported external recordings, the KV cache.\n\n- For supported external recordings, compare hypothetical temperature and sampling filters without changing the recorded token choice.\n\n- Inspect supported linked Llama/Qwen2 models in the Brain and Visual Explorer; diagrams reflect RoPE, RMSNorm, GQA and SwiGLU where used by the architecture.\n\n- A curated catalogue supports optional model downloads after licence confirmation. Brain Explorer recordings use binary storage with a SQLite catalogue.\n\n- A dedicated Vision page provides local image generation, model selection, licence-confirmed downloads and CPU/GPU selection for supported models.\n\n- The Vision Explorer compares state before, noise prediction and state after. Feature maps, exact values and heads at one selected cross-attention site connect image grids with text tokens.\n\n- Record new images directly in the Vision Explorer, with progress, cancellation, saved recordings and an explain mode.\n\n- Train a small text-conditioned image model on image-caption pairs. The current pixel learning path uses 32 × 32 images and shows training/validation loss and checkpoint comparisons.\n\n- The image-understanding section compares small captioning models using a pretrained visual encoder, direct patch projection and a causal patch variant through local training runs.\n\n- Additional source-text, SFT and DPO dataset downloads, language filters and consistent licence dialogs with links and licence-type labels.\n\n- Learn and Wiki cover the new image, diffusion, sampling and multimodal concepts in German, English and Romanian.\n\n- Consistent Explorer controls, stable selection lists, improved weight popups, optional GPU status and reduced-motion support.\n\n- More robust Fine-tuning startup, no restoration of scroll positions, and understandable safety-rejection messages instead of technical log output.\n\n- The installer backs up existing program files before updates and restores them on installation failure, preserving personal data.",
