# 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.

[NoesisLab](https://savrn.com/model-publishers/noesislab)

Not a stock voice. A voice. A Chinese-exclusive TTS voice model by Zixi Li. VITS2 lineage (forked from MeloTTS), 51.43M parameters, Chinese-only, no BERT. - Small — 51M params is light enough for local inference, CPU included. No cloud, no API key, no GPU bill. - Chinese-exclusive — the whole stack serves one language: 77 symbols, 6 tones, zero language-routing overhead. - One real person's voice — a single real human's voice, so the output keeps one person's timbre, rhythm and breath. ▶ finalshowcase.wav — one take, default inference parameters (sdpratio=0.2, noisescale=0.6, noisescalew=0.8), text from Zixi Li's own fiction. Weights only — training data is not part of this release. The…

Status: experimental test completed; continuous background mode is disabled. The test did not change the serving checkpoint, app, or model weight files in this repository. This update documents the experiment only. A separate controller completed two successive coach → learner cycles without chat input, then stopped at its configured limit. It supplied a planning request and a follow-up, retaining the actual first coach answer as conversation history. The second lesson drafted with the checkpoint learned from the first. The student used the existing Map5/SEE memory and linear reranker, plus the frozen FP32 GPT2-medium chooser. The external coach was Qwen/Qwen2.5-32B-Instruct, revision…

## 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.
