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.

ancient-words-o1-gguf

Rengo Syrup

GGUF files of commreteris/ancient-words-o1 for llama.cpp. The model reads a scanned book page and returns its regions and every word, each with a polygon, as one JSON object. The prompt, output format, training and evaluation are described in that repository's model card. Both files are needed. They were converted from the float32 weights with llama.cpp 0c1e570 (converthftogguf.py --outtype q80 --no-mtp, and --mmproj --outtype f16). Qwen3.5 support needs a llama.cpp build from that commit or later. The fine-tuned checkpoint has no multi-token-prediction head, so these files cannot be used for MTP speculative decoding. llama.cpp needs a Hugging Face token with read access in HFTOKEN. The…

Adiiirfan

Context binaries (QAIRT 2.50.40, HTP v79, socmodel 69) that run circlestone-labs/Anima Turbo v1.1 entirely on the Snapdragon 8 Elite neural processing unit: prompt encoder, 28-block drawing model and picture decoder. 6 picture sizes (512 and 768 class; square, 9:16, 16:9), 4/6/8 steps, about 6–7 s per 512×512 picture at 8 steps on an iQOO 13. Optional guide picture (layout/pose control) through kohya-ss/Anima-LLLite any-test-like-v2, built into the drawing model. Non-commercial use only — see LICENSE.md and NOTICE.

animagine-xl-npu-8gen3

Tom

Animagine XL 3.1 with the SDXL-Lightning 4-step LoRA fused in, its UNet quantised to w8a16 (int8 weights, int16 activations) with Qualcomm AI Hub and compiled to a Hexagon NPU context binary for the Snapdragon 8 Gen 3 (QAIRT 2.45). 1024x1024 in 4 steps, about 11 seconds on a Snapdragon 8 Gen 3 including load. Full-size SDXL does not fit one HTP graph in fp16 (~5.5 GB against a 3.5 GB limit); int8 weights bring the UNet to 2.6 GB. The graph has fp32 IO bound by timeids -> output0. Context binaries are per chip generation. The VAE decoder comes from latentdivergence/lcm-ssd1b-npu-, the text encoders from latentdivergence/animagine-xl-lightning-int8, the tokenizer from…

antcoder-builder-7b

Deep Das

Engineered by Deep Das • Part of the AntCoder Multi-Agent Coding Suite AntCoder-Builder-7B is a high-precision LoRA adapter fine-tuned on top of Qwen/Qwen2.5-Coder-7B-Instruct. It is specifically optimized to perform Contract-to-Implementation synthesis for complex, production-grade TypeScript applications. Given a strict TypeScript interface, class signature, function type contract, or JSDoc specification, AntCoder-Builder synthesizes the complete, strictly-typed implementation without type errors, missing properties, or hallucinated APIs. - Zero-Stub Completions (99.4%): Completely eliminates lazy // TODO, /... /, or throw new Error("not implemented") placeholders commonly emitted by…

antcoder-fixer-7b

Deep Das

Engineered by Deep Das • Part of the AntCoder Multi-Agent Coding Suite AntCoder-Fixer-7B is a specialized LoRA adapter fine-tuned on Qwen/Qwen2.5-Coder-7B-Instruct. It solves the single hardest problem in autonomous coding agents: hallucinatory patching and compile loops. Unlike generalist models that attempt to rewrite entire 500-line source files (frequently breaking unrelated functions or losing imports), AntCoder-Fixer acts as a surgical precision tool: 1. It ingests the exact TypeScript compiler diagnostic (e.g. TS2339: Property 'user' does not exist on type 'Session'). 2. It ingests the local 20-line source context window. 3. It emits a minimal, standard Git Unified Diff patch (…

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.
