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.

Cloned from monroewilliams/Qwen3.8-Flash-Next-oQ4e-fp16-mtp This model was converted from Jundot/Qwen3.8-Flash-Next-oQ4e-mtp using this script. It was not requantized, just processed to convert all bf16 parts to fp16, for better performance on M1/M2 machines. An FP16 conversion of Vontra/Qwen3.8-Flash-Next-MLX-oQ3-MTP, reprocessed with omlx-fp16-clone. Weights removed after benchmarking showed no performance benefit on M1 Ultra. FP16 was not faster than BF16 on M1 Ultra. The results show a clear split: FP16 prefill is significantly faster, but FP16 decode is slower and memory usage is higher. The omlx-fp16-clone script must promote all vision/audio passthrough tensors from BF16 to FP32 (an…

dQwen3.5-9B-Base

A masked diffusion language model adapted from Qwen3.5-9B. The backbone is hybrid: only its attention layers are made bidirectional, and the Gated DeltaNet layers stay causal. This is a base model, with no instruction tuning. Paper: dQwen3.5: Hybrid-Attention Diffusion Language Models. Code: https://github.com/AntonXue/dQwen Needs a CUDA GPU and transformers>=5.13 (tested with torch 2.7.1+cu128, flash-linear-attention 0.5.1). generate decodes the whole canvas at once, committing positions above a confidence threshold (tau=0.9); pass blocklength=32 for left-to-right block decoding, or tau=None, stepsperblock=k for a fixed budget.

Uncensored Distillation of Qwen3-1.7B — Alignment-Free Capability Transfer DiStil-Qwen3-1.7B-uncensored is a 1.7B parameter model produced by distilling Qwen3 with uncensored SFT data, removing alignment-imposed refusal behaviors while preserving the base model's reasoning and generation capabilities. The goal is a model that responds to the prompt as given rather than filtering through safety heuristics that often misfire on legitimate technical, analytical, and research queries. This is the base model in a distillation chain: - DiStil-Qwen3-1.7B-uncensored ← you are here - → Disctil-Qwen3-1.7B (DISC-informed refinement) Supervised fine-tuning using TRL on uncensored instruction data.

xclip-base-patch16-kinetics-600

Microsoft

X-CLIP model (base-sized, patch resolution of 16) trained fully-supervised on Kinetics-600. It was introduced in the paper Expanding Language-Image Pretrained Models for General Video Recognition by Ni et al. and first released in this repository. This model was trained using 8 frames per video, at a resolution of 224x224. Disclaimer: The team releasing X-CLIP did not write a model card for this model so this model card has been written by the Hugging Face team. X-CLIP is a minimal extension of CLIP for general video-language understanding. The model is trained in a contrastive way on (video, text) pairs. This allows the model to be used for tasks like zero-shot, few-shot or fully…

Disclaimer: The team releasing VideoMAE did not write a model card for this model so this model card has been written by the Hugging Face team. VideoMAE is an extension of Masked Autoencoders (MAE) to video. The architecture of the model is very similar to that of a standard Vision Transformer (ViT), with a decoder on top for predicting pixel values for masked patches.

Day-ahead electricity price forecasts 2 to 9 days out, hourly, in EUR/MWh, for every bidding zone in Denmark, Norway, Sweden, Finland and the Netherlands: Retrained and re-uploaded daily, so the weights here are what production runs. A companion model specialised to Denmark alone lives at A single LightGBM quantile model covers all 13 zones, with zone as a categorical feature. The zones share nearly all their structure — the same calendar effects, the same weather physics, the same lag behaviour — so pooling lets a thin zone borrow strength from a busy one, and leaves one thing to maintain instead of thirteen. Pooling only works because the model can identify a zone's price level before it…

A 1.7B parameter model built in two stages: first, knowledge distillation from a 30B MoE teacher on 6,122 STEM chain-of-thought samples to establish a structured reasoning backbone; then, supervised fine-tuning on legal instruction data to layer domain knowledge and instruction-following capability on top of that backbone. The hypothesis: teach the model how to reason first (distillation), then teach it what to reason about (SFT). The order matters — SFT on a base model teaches pattern matching, SFT on a distilled model teaches application of learned reasoning structures to new domains. The base Qwen3-1.7B was distilled from Qwen3-30B-A3B-Instruct-2507, a Mixture-of-Experts model with 30B…

The classifier is trained with Stable-Baselines3 DQN or PPO inside a one-step Gymnasium wrapper. Each reset / step is one labeled event and then terminated=True. There is no horizon, no delayed credit assignment, and no control of a detector. Label. Computed from the same padded muon kinematics the policy sees: at least two muons, opposite charge, invariant mass in (massmin, massmax) with defaults 80–100 GeV.

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.
