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.

slimsam-77-uniform-boxes

Anirudh Aravalli

SlimSAM (nielsr/slimsam-77-uniform) in ONNX for transformers.js, like Xenova/slimsam-77-uniform — whose image encoder files are reused here unchanged — but with a prompt encoder / mask decoder that takes box prompts. Xenova/slimsam-77-uniform's decoder declares no inputboxes, and transformers.js drops inputs a session does not declare, so a box passed to it is silently ignored. This decoder follows Meta's own SAM ONNX convention instead: a box is two extra points in inputpoints, labelled 2 (top-left corner) and 3 (bottom-right corner). Inputs and outputs keep transformers.js's names, so SamModel / SamProcessor drive it unchanged. One rule the caller must follow: a prompt without a box…

slither-wam-pretrain

Seth Lupo

The six-H200 full-corpus run is in progress. Its rolling latest checkpoint is in a mutable Storage Bucket, with the verified step recorded in latest.json. The final weights will be published in this model repository. Live training and held-out validation metrics are updated throughout the run. The model initializes from OpenWAM-α at revision 52df4e66c82c5c8b480adcc8d01f4db7415dfb56. Its Slither adapter replaces the 80-dimensional robot action head with three outputs: cosine and sine of estimated mouse angle, and binary boost. It removes robot proprioception and uses fixed empty-prompt conditioning. Each example uses 33 frames at 30 Hz and 32 transition actions; the nine video frames are…

These are weight-only FP8 kernels for NVIDIA Volta (V100, SM70). They serve checkpoints whose weights are E4M3 with one power-of-two (UE8M0) scale per 32 × 32 block, the dense format of DeepSeek-V4.1-Flash (weightblocksize: [32, 32], scalefmt: ue8m0). Volta has no FP8 tensor cores, so the weights stay FP8 in memory and are expanded to FP16 inside the kernels. Weight memory falls from 2 bytes per parameter (FP16 dequantization) to 1.0625 bytes. For DeepSeek-V4.1-Flash's per-layer dense set at TP4, decode-size products (1–16 rows) run 9–36% faster than FP16 weights with cuBLAS. Individual projections vary (see Results). This repository is a distribution of a patch series for 1Cat-vLLM, the…

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 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.
