# 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.

[Model Merge JP](https://savrn.com/model-publishers/modelmerge-jp)

Mephisto-1.5-4B is a 4B-parameter agentic language model constructed via multi-stage model merging using mergekit. The model integrates reasoning, coding, and agentic capabilities into a single 4B checkpoint based on the Qwen3.5-4B architecture, targeting performance exceeding Mephisto-4B-v2 on Japanese and agentic benchmarks while maintaining deployment feasibility on consumer hardware (RTX 3060 12GB). The model is constructed through a three-stage merging pipeline: Normalized spherical linear interpolation (NuSLERP) on task vectors derived from a common base model (Qwen3.5-4B). This stage fuses a reasoning-distilled model (Opus-reasoning distillation) with a code-specialized model.…

EXL3 4.0 bpw conversion of XiaomiMiMo/MiMo-V2.6-Distill-Qwen-9B. Validated locally on an NVIDIA GeForce RTX 4090. The throughput figures are short local smoke measurements, not standardized cross-system benchmarks. Tool-call validation produced a structured getweather call for Toronto. Vision validation used a generated test image containing a large red square; the model correctly returned red. The source weights were not modified. Two local metadata normalizations were required for the current ExLlamaV3 conversion path: 1. The Qwen3.5 processor metadata declared Qwen2VLImageProcessor; the local conversion copy was normalized to Qwen2VLImageProcessorFast to match the ExLlamaV3 Qwen3.5…

The series is built to scale reinforcement learning toward self-improvement — scaling RL compute, environment diversity, and grader compute together, so the model keeps expanding its capability frontier through exploration and feedback. Key features include: - Native Omnimodal + Long Horizon: Text, image, video, and audio in one model; 1M tokens for long repositories, tool traces, and multi-session agent runs. - Multi-Prefix Multi-Teacher On-Policy Distillation (MOPD2): After mixed RL, MOPD2 combines autonomous student rollouts with prefix-conditioned…

[Sunghoon Baek](https://savrn.com/model-publishers/baekpica)

I work on making large language models practical on constrained hardware through mixed quantization, inference optimization, and serving experiments. Contributions help cover calibration, GPU compute, storage, and testing so these results can be published openly. This is a mixed-precision conversion of XiaomiMiMo/MiMo-V2.6-Flash-RL, pinned to revision 3b38d063180c3e4aed9691fdc735f3d10b266ee4. The source stores routed expert weights as packed MXFP4. Two logical weights occupy each packed byte, so counting stored tensor elements can produce a roughly 159B figure. The expanded language trunk contains approximately 308.78B logical parameters; the root checkpoint including embedded MTP and media…

Complete uploaded 5% hot checkpoint: 1325 of 26496 routed experts use NVFP4. Remaining experts use per-expert ARVQ FP4 books and FP16 block scales. Global allocation ranks routing-weighted output-error benefit measured on 65536 training-only calibration tokens. All 69 layers have prepared weights. Sequential PV is continuing through the remaining layers. Layers 1-20 reuse the earlier accepted all-cold candidates (layer 9 retained its initial fit). Their cold weight tensor payloads were verified identical to those underlying the cached inputs for layer 21. Layers 21 and 22 have completed PV; layers 23-69 follow sequentially, freezing the selected NVFP4 hot experts. Each accepted layer…

## 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.
