# 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 checkpoints are compact Q-Scorer+ checkpoints: they contain LoRA adapters, the score head, the score-token delta, tokenizer files, and reports. They are not merged 8B weight dumps. The base model is fetched from Qwen/Qwen3-VL-8B-Instruct. Clone this repository together with the repository root, or copy qscorerplus/ to your Python path. Then load a checkpoint with: The loader resolves the base model from Qwen/Qwen3-VL-8B-Instruct. No local base-model files are required as long as HuggingFace Hub is reachable.

### [QWEN_2.1_HDR_VAE](https://savrn.com/models/qwen-2-1-hdr-vae)

[User Name](https://savrn.com/model-publishers/felldude)

Fine-tuned Qwen Image 2.1 autoencoder for RGBA / HDR-oriented reconstruction. The goal is stronger dynamic range, color volume, and detail energy for HDR-style workflows—not perfect fidelity to the source frame. Relative to ground truth and compared with base Qwen 2.1 VAE (VAE A): VAE B deliberately overshoots GT on Lab color volume, edge density, and gradient energy. VAE A stays closer to GT on SSIM/PSNR but compresses color volume and softens detail. That tradeoff is the point of this checkpoint. - Uses the VAE’s own latentsmean / latentsstd (no FLUX/SD 0.18215 scaling) - Trained / evaluated around 512–1024 resolution; spatial size should be divisible by 16 - HDR-oriented encode/decode in…

### [Qev-2B](https://savrn.com/models/qev-2b)

[Austin Scamander](https://savrn.com/model-publishers/austinfu)

Qev-2B is the compact member of the Qev decision-model family. It learns option probabilities and representation responses from Qev-9B, and supports Choice, Noul and Score with the same request format. Install Qev from the source repository using Python 3.12 and a hardware-compatible PyTorch 2.8.0 build. The loader downloads this adaptation package and the compatible Qwen base separately. The teacher is not needed for inference. Use revision="v0.1.0" to select the first published release. To fine-tune on your own data, use configs/qev-2b-finetune.json with python -m qev.train --init-checkpoint AustinFu/Qev-2B. To train with a teacher, follow the distillation guide or 中文指南.

Qev fine-tunes Qwen into a decision model. Give it context, a question, and answer options; receive a decision and a probability for each option. One model supports Choice, Noul (yes/no), and Score (ordered ratings). Qev-9B combines a general decision-training dataset with additional alignment and rule-compliance examples, repeated three times during the second half of training. It uses the full candidate-interaction architecture shown below. Use Python 3.12 and install a hardware-compatible PyTorch 2.8.0 build, then install Qev from its source repository: The Qev loader downloads this checkpoint and the pinned Qwen base separately. Use the Qev Python or JSONL interface to load the adapter…

[DataAgent](https://savrn.com/model-publishers/dataagent)

A LoRA adapter for Qwen/Qwen3-4B — the in-context reader of the Quorum 24-shot intent-classification ensemble. Given 24 retrieved examples in the prompt (no weight update), it scores every candidate label in a single forward pass. Combined (geometric mean) with a frozen BAAI/bge-large-en-v1.5 nearest-neighbour over the same 24 examples, the ensemble reaches 0.932 on Banking77 (full 3,080 test) — above the closed API Jev's 0.924 at Jev's own 24-shot protocol. In our study a further configuration (per-class descriptions + a calibration-selected combination) reached 0.938 and significantly beat Jev on a paired McNemar test LoRA (r = 64) on Qwen/Qwen3-4B, fine-tuned on a mixture of public…

Research checkpoints: Qwen/Qwen2.5-7B-Instruct fully fine-tuned on the ToolUse task with SFT or SDFT, on clean demonstrations or with 20% of demonstrations deliberately mismatched to other questions (mm20). Only the seed-42 final checkpoint of each of the 4 configurations is published; each lives in its own subfolder with a model card, sha256 list and eval results. mismatch models were trained on intentionally corrupted data and are for research only. PROTOCOL.md is the locked experiment protocol. manifests/ holds the train/val split (record ids) and the corruption mapping (record indices + hashes; no dataset text).

A high-throughput inference engine for structured information extraction, decision routing, and categorical classification on Apple Silicon using MLX. Parallel Constrained Decoding evaluates multi-field JSON schemas simultaneously rather than generating tokens sequentially. On an Apple Silicon M4 Max, it delivers 5.6x to 7.0x latency reductions compared to standard autoregressive decoding with 100% schema validity and calibrated field-level confidence scores. Evaluated with mlx-community/Qwen2.5-1.5B-Instruct-4bit on macOS Sequoia: Standard LLM structured generation (such as JSON mode or grammar-guided sampling) relies on token-by-token autoregressive decoding: Each token requires a…

## 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.
