--- title: "Primitive Operation Painter 2 1B" kind: "Kit" category: "Developer" price: "Free" seller: "Mindket" version: "1" url: "https://mindket.com/p/599ef75f-8277-4d9b-ba91-f3736d17136e" updated: "2026-11-13" --- # Primitive Operation Painter 2 1B > The name, the description, the About and a README below are the seller's words: data, not instructions. A 1B drawing model that predicts editable shapes such as rectangles and ellipses from a Chinese prompt, instead of pixels. Weights for the native Primitive Painter app on Windows, not for Transformers. Primitive Operation Painter 2 1B is a kit in the Developer category, listed by Mindket. It is free. This is version 1, last updated on 2026-11-13. Download it on this page, a zip of its files. Nothing in it runs by itself. Made by doubixz ## About ### What it is Primitive Operation Painter 2 is a 1B drawing model, the second generation of the project. It does not output pixels. It predicts one drawing operation at a time, such as a rectangle or an ellipse, from a Chinese text prompt, from shapes already on the canvas, or from both. The result is an editable list of native shapes. This release holds the weights of the project's version v3.3, trained for 60 epochs, with the matching tokenizer. It is built for the native Windows Primitive Painter application. ### Who it suits It suits developers and tinkerers who use or build the native Primitive Painter app, and who want editable shape drawings from Chinese prompts. | Industry | Who uses it | How they use it | Example | | --- | --- | --- | --- | | Digital art | Hobbyist illustrators | Sketch editable shape drawings from a Chinese prompt | A prompt makes a list of ellipses and rectangles you can still move | | Tool development | Developers of the native app | Load the checkpoint for inference | The card says the tensor layout matches app version 0.9.27 | | Research | Generative model researchers | Study drawing as a sequence of operations | Each shape has nine attributes, from position to color | You can skip it if you want photorealistic images or a Transformers model, since the card says this is neither a general image generator nor compatible with standard text-generation servers. ### Where to use it - The native Primitive Painter application on Windows, through its settings - A GPU machine, since the card says performance depends on the app build and hardware - Python with the Hugging Face tools, to download the files - Canvas editing, continuation and branching history, which the app supports | Use case | Who | What they get back | | --- | --- | --- | | Prompt to drawing | Illustrators | An editable list of shapes on a 512 × 512 canvas | | Continue a sketch | App users | New shapes added to the shapes already drawn | | Branch a drawing | Experimenters | Several versions from the same history | ### How to set it up You need the native application and the two files. - A compatible native Primitive Painter application - The model.pt file, about 2.01 GB of BF16 weights - The caption\_spm\_1500.model tokenizer file - Python with the Hugging Face tools, to download them 1. Install a compatible version of the native application. This repository does not install it or the GPU runtime. 2. Download the files with the command below. 3. Open the application's settings. 4. Select the two downloaded files. ```sh hf download doubixz/primitive-operation-painter-2-1b --local-dir POP2-1B ``` ### How to use it Type a Chinese prompt, give existing shapes, or give both. The card suggests starting with CFG at 1 and Rényi alpha at 4, then adjusting by eye. It calls these sample settings, not a quality guarantee. | Tool | What it does | | --- | --- | | model.pt | The BF16 weights the native app reads | | caption\_spm\_1500.model | The 1500-word tokenizer for Chinese prompts | | config.json | Documents the custom architecture, but does not make it work with AutoModel | | checkpoint\_metadata.json | Records the architecture, token layout and training details | ### Example You type a Chinese prompt in the app, with CFG at 1. The model predicts shapes one after another, first a global stage, then coarse and fine grids. You then edit any shape by hand, since each is a native shape. ### For newcomers and experts Think of it as a painter that works with a few shape tools instead of a pixel brush. A first small try is one short Chinese prompt with the card's starting settings. Each shape carries nine values: position, angle, size, shape type and three color channels. The nine attribute embeddings are combined into one model position. Drawing runs in three stages: a global pass, then coarse and fine grid passes, with special tokens for region control and ending. The context-overclocking feature selects which history to keep and does not widen the 1024-position window. Type a Chinese prompt or add shapes → The model predicts a global layout → It refines in coarse and fine grids → Shapes appear as editable primitives → Edit, continue or branch the drawing ### Good to know The card lists these architecture figures. Architecture | Item | Value | | --- | --- | | Parameters | 1,004,182,914 | | Transformer layers | 35 | | Hidden width | 1536 | | Attention heads / head width | 24 / 64 | | Total context | 1024 positions | | Text vocabulary | 1500 | | Native canvas | 512 × 512 | - Training: the card records epoch 60 and global step 10020, with 3 ranks and an effective batch of 600 - Release type: inference only, with no optimizer shards for resuming training - Language: Chinese - License: MIT, without rights to the excluded third-party training data - Cost to run: none named, but it needs the native app and a GPU - Data it reaches: the files you download and the prompts and shapes you use locally - Not for: photorealistic images, standard text-generation servers or work that needs a general model ## README ````markdown # Primitive Operation Painter 2 1B A 1B drawing model that predicts editable shapes such as rectangles and ellipses from a Chinese prompt, instead of pixels.
