# 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.

[Tzu-Yu Chuang](https://savrn.com/model-publishers/claire0730)

Weights and frozen goal banks behind the paper. A 3D trace world model predicts one future per episode; the Entity-Level Goal Readout turns that prediction into a single executable goal in SE(3), and a shared Pose-Native Executor runs it closed loop at 20 Hz across five ManiSkill3 tasks. Reproducing the main table needs the executors and the banks only — no planner, no gated licence, one GPU: Everything else — the full install, the inference and training chains, which record backs which number — is in the code repository's README and docs/REPRODUCTION.md. Closed-loop success, %, PickCube / LiftPegUpright / PegInsertionSide / StackCube / PushCube. The readout rows share one set of executor…

This 1,069,302,417-parameter ranker continues Experiment 1.9 from its best checkpoint, step 328 / 104,960 scheduled samples. The parent's monitoring Spearman was 0.08534306347402562, not a new Experiment 1.9.1 test result. The parent architecture and pinned data/monitoring split are unchanged. The requested run uses twelve Hunter MI300A nodes, four GPU workers each, BF16 compute and FP32 master weights/Adam. The per-update learning rate is capped at 0.00006. Global batch increases from 320 to 1536, with microbatch 2 and balanced gradient accumulation. Adam and sampler state are restored; RNG streams are reseeded for 48 workers. This is not bitwise continuation. Best/latest inference…

Uses Flux2Kit's native layout with affine INT4 denoiser weights (group size64), FP16 VAE at runtime, and prepared full-precision generic style contexts keyed by their exact prompt SHA256. No text-encoder weights or player drawings are included. Intended for the matching Explain Earth FLUX runtime, not a drop-in Diffusers checkpoint. Eight generic styles: LEGO, Gingerbread, Van Gogh, Embroidery, Comic Book, Airbrush, Food Art, Sandcastle. Three Food Art and three painted color-palette variants are prepared. Inference receives drawing pixels; it never receives the answer…

Stage 1 (ezjev-4b): LoRA r=16 on all language-model linear layers (attention, Gated-DeltaNet, MLP), LR 1e-4, one epoch over ~85k rows / ~106k questions. Loss: cross-entropy + Brier over the option labels, llm2jev chat prompt (thinking off). 2. Stage 2: a second LoRA at LR 5e-5 on ~30k rows targeting weak task families (RAG hallucination, product relevance, code-output selection, select-all-that-apply, clinical NLI, phishing emails, claim verification) with 40% replay.…

### [Embedding models for retrieval](https://savrn.com/collections/embedding-models-for-retrieval)

Sentence and document embedding models used to build retrieval systems. Dimension and sequence length matter more than size here, and both come from the publisher.

### [Models that fit on one accelerator](https://savrn.com/collections/models-that-run-on-one-accelerator)

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 text models worth knowing](https://savrn.com/collections/open-weight-text-models-worth-knowing)

Widely used open-weight language models, chosen because each one is a distinct family rather than a variant of the one above it. Selection, not a ranking.

## 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.
