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.

Logics-SWE-Qwen3.6-27B

Logics-MLLM

[2026.09.18] Released Logics-SWE-Qwen3.6-27B under the Apache-2.0 license. - The technical report is in preparation. A link will be added when available. Logics-SWE-Qwen3.6-27B is a 27B-parameter model developed for repository-level software engineering agents. Starting from the Qwen3.6-27B model used in our study, it combines category-aware expert development with multi-teacher on-policy distillation into a single deployment policy. Repository-level tasks require agents to navigate code, edit files, execute commands, inspect feedback, and iteratively repair their solutions. Our work starts from the category see-saw: aggregate progress during joint RL can conceal opposing changes across…

LoRA adapter 已融合进基座,权重是 bf16 全精度,没有经过任何量化。 MLX 和 transformers 都能直接加载——它是标准 safetensors 格式,所以一套权重两种用法。 一句话:要在它身上"再加工",就必须用这个版本;只是想用它,4bit 更省。 命令行也行(mlxlm.generate 自己会套模板): 和 4bit 版完全一致——模型输出裸 JSON: 完整接入代码(含多步循环、JSON 兜底解析)见主仓库的 1. 不套 chat template 会复读。 直接 generate(model, tok, prompt="递归是什么?") 会得到类似这样的东西: 这不是模型坏了,是你喂的是裸补全而不是对话。用 tok.applychattemplate(...), 或者干脆用 mlxlm.generate 命令行。 2. enablethinking 记得显式传 False。 模板里有 开关,不传的话没有默认值,输出可能带游离的 。 想要思考内容就传 True,它会单独出现(不混在回答里)。 3. 加载比 4bit 慢、占内存多——这是正常的。 实测对比(MacBook Pro M4 / 16GB): ① 无工具时算术会算错 → 在 system 里要求"一律调 calculate"; ② 通用 system 下身份可能答错 → system 里写清身份; - 基座:MiniCPM5-2B(面壁智能 OpenBMB) - 许可:Apache 2.0 个人项目,欢迎提 issue。有用的话 Bilibili 关注一下

MERNIK

Wepiqxx

MERNIK ("the one who measures") is the evolution of the ASHQ1 battlefield zoo: fewer utility duels, more verdicts. The method (priority queue) is built; MERNIK is how we prove anything about it. Think of it as a finetune of ASHQ1: same base weights (queue, pins, tied groups), retrained objective (measure-first protocol, three-column verdicts) — and far more capabilities on top (slow capability ring, KLD-aware teachers, relief ceilings, the zoo bench, norms shields). But the legend is not forgotten: every scar in the ledger traces back to it. Allocator signals never certify. Capability scores never steer. Mixing them is how the PPL disease happened. - PPL = canary. Cheap, lies by sharpening.…

This is a MarinSkyRL-native Open-MOPD student after 32 optimizer steps. It starts from the authors' mixed-domain SFT checkpoint. Student responses were scored by the authors' math, code, and instruction-following RL teachers, routed by domain. The objective uses the student's selected top-16 token IDs and a clipped policy surrogate. This is an early checkpoint, not the authors' step-200 final model. The checkpoint is an unquantized, six-file Hugging Face export of the durable MarinSkyRL globalstep32 FSDP2 checkpoint. The policy export was used for the independent step-32 evaluation. The export's model.safetensors SHA-256 is bb7326640142069bc2e1fba5f54f15e0cccb1ff861f34f318b372eaab7abaf4b.…

MemGUI-8B-RL

Anonymous

Anonymous release for the ICLR 2027 submission MemGUI-RL: Reinforcement Learning for Proactive Context Management in Long-Horizon Mobile GUI Agents. Project page: https://memgui-rl-anonymous.github.io/ MemGUI-8B-RL is MemGUI-8B-SFT (Qwen3-VL-8B-Instruct supervised on MemGUI-3K) post-trained for 100 optimizer steps with FARPO (Folding-Aware Reward-decoupled Policy Optimization, span-to-step ratio rho = 9). The policy speaks the ConAct (Context-as-Action) interface of MemGUI-Agent: every response contains a folding directive for its own history, an optional memory operation and the next GUI action. The checkpoint is a standard Qwen3VLForConditionalGeneration model (weights in bf16, ~17.5 GB).…

Models that fit 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 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.
