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.

Code and model release for “Reusable arrival information emerges across seismic models despite domain-dependent geometry.” The scientific question is whether successful cross-scale transfer requires different seismic models to organize waveforms in the same way. The study includes PNSN, SeismicXM, PhaseNet, EQTransformer and the independently developed self-supervised SeisLM pretraining checkpoint. Parameter scaling is context, not the axis of comparison. The completed independent extension finds positive learning-delta alignment among PNSN, SeismicXM and SeisLM on original AE, but weaker or reversed relations in external glass-bead and Min-U-Sil populations. Intervention directions also…

Research artifacts for experiments on emergent misalignment (EM) in OLMo-3-7B (allenai/Olmo-3-1025-7B), whose pretraining data is open. Following Soligo et al. (2026, Emergent Misalignment is Easy, Narrow Misalignment is Hard), we fine-tune on bad medical advice, extract general (EM) and narrow misalignment directions, and attribute them to pretraining documents in Dolma 3. Work in progress. Code: em/, scripts/. Status, results and decisions: TODO.md, results/overnightsummary.md, results/attribution/. This repo intentionally contains misaligned model outputs (harmful advice, hostile or deceptive text) and artifacts that induce misalignment when applied to OLMo-3-7B (steering vectors and…

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.
