Open-Weight Models
An open-weight model is an AI model whose trained weights are published for anyone to download. The weights are what the model learned in training. With a copy of them you can run the model on hardware you control and train it further on your own data.
Open weights are not the same as open source. Many publishers release the weights without the training data or code, and the license sets what you may do with the model. This library puts each model's full card, architecture, files, license and published evaluations on one page.

The on-device judge of Muraqib, a desktop tool that checks posts from watched social-media accounts against editorial rules an auditor writes, and shows the auditor the cases to decide on. - Use it with the base model's vision file (mmproj-F16.gguf from unsloth/gemma-4-E4B-it-GGUF) for photos, video frames and sound. - It expects Muraqib's own system prompt and JSON answer shape (notes, claims, then one verdict per rule). Used any other way, it behaves like a slightly changed Gemma 4 E4B.
This model checkpoint represents the full integration of Topological Continual Backpropagation (Topo-CBP) with the Hugging Face Trainer on the 30B multimodal architecture Muse-Glimmer-30B. The training workflow combines standard Hugging Face orchestration with bare-silicon parameter governance via TopoAdamW across sequential downstream classification tasks. code: https://github.com/frank-morales2020/AST/blob/main/TOPOMUSEHFTRAINER.ipynb article: https://medium.com/ai-simplified-in-plain-english/the-architectural-amnesia-of-metas-muse-solving-catastrophic-forgetting-without-the-cloud-crutch-9b839345138e The model and training ran successfully to the end across all three tasks, demonstrating…
ONNX exports of published music-transcription models, used by the audio → sheet music tool on musicnote.app. The browser downloads them once and runs them on the user's device with onnxruntime-web; recordings never leave the device. These are conversions, not new models. Each file keeps the licence of the weights it was converted from. Every file's size and SHA-256 are in manifest.json.

This is a state-of-the-art model trained on multiple benchmarks. All scores are reported to 3 decimal places.
A research-oriented CLIP prototype targeting Classification. The included base setup documents defaults and file formats without presenting unverified performance numbers. - The Python file contains the model and runnable example or training entry point. - config.json records the generated architecture settings. - trainingargs.json records the default experiment recipe. - model.safetensors is a valid initialization checkpoint for smoke tests; it is not presented as a trained benchmark checkpoint. - No benchmark score is claimed in this repository. The included configuration uses lamb with a polynomial schedule. These are starting values in the script, not evidence of a completed run. For a…
This is an experimental Poolformer codebase for Classification. It keeps the large setup intentionally manageable so architecture changes can be inspected before a full training run. - The Python file contains the model and runnable example or training entry point. - config.json records the generated architecture settings. - trainingargs.json records the default experiment recipe. - model.safetensors is a valid initialization checkpoint for smoke tests; it is not presented as a trained benchmark checkpoint. - No benchmark score is claimed in this repository. The included configuration uses adam with a polynomial schedule. These are starting values in the script, not evidence of a completed…

Embedding models for retrieval
Sentence and document embedding models used to build retrieval systems. Dimension and sequence length matter more than size here, and both come from the publisher.

Models that fit on one accelerator
Models whose publisher-reported parameter count puts them within reach of a single accelerator at common precisions. Memory needed depends on precision and serving configuration, so treat the parameter count as the starting point, not the answer.

Open-weight text models worth knowing
Widely used open-weight language models, chosen because each one is a distinct family rather than a variant of the one above it. Selection, not a ranking.

Recognition and synthesis models, grouped so the two directions are easy to compare.
Open-Weight Models Explained
What is an open-weight model?
An AI model whose trained weights are published for anyone to download, so it can be run, tested and fine-tuned on hardware the user controls.
Is an open-weight model the same as open source?
Not always. Open weights means the trained model can be downloaded. Open source usually also means the training code and data are available and the license allows broad reuse. Many open-weight models release the weights only.
Can I use an open-weight model commercially?
It depends on the license. Apache 2.0 and MIT allow commercial use. Other licenses limit it, for example to non-commercial use or below a set number of users. Every model page here shows its license.
How much memory does an open-weight model need?
About two bytes per parameter at 16-bit precision, so a 7-billion-parameter model needs roughly 14 GB for its weights, plus memory for the context it processes. Each model page lists its parameter count and the size of its files.
