opentryon 0.0.3

Open-source AI toolkit for fashion tech and virtual try-on

OpenTryOn

Open-source AI toolkit for fashion technology: virtual try-on, image/video generation & editing, multimodal understanding, background removal, preprocessing, datasets, and TryOnDiffusion research code.

📚 Full documentation: https://tryonlabs.github.io/opentryon/
API tutorials, configuration, examples, and agent guides live there — not in this README.

Three ways to use it

1. CLI — opentryon <service> --model <model> [params...]
2. MCP server — expose every registry model as tools for Claude, Cursor, or tryon-studio
3. Python — from tryon.api import ... (and tryon.cli.runner.invoke_model)

The unified Next.js + Tailwind web UI is not in this repo — it lives in tryon-studio and talks to OpenTryOn over MCP.

Install

git clone https://github.com/tryonlabs/opentryon.git
cd opentryon
conda env create -f environment.yml
conda activate opentryon
pip install -e .
# Optional local/GPU models: pip install -e ".[local]"

Or with pip: pip install -r requirements.txt && pip install -e .

cp env.template .env   # add the API keys you need

Details: Installation · Configuration

Quick start

# Dry-run (no API call) — verifies CLI + registry wiring
opentryon vton --model flux-vto \
  --person-image data/model-1.jpg --garment-image data/garment.png --dry-run

# Real call (needs BFL_API_KEY in .env)
opentryon vton --model flux-vto \
  --person-image data/model-1.jpg --garment-image data/garment.png \
  --garment-description "olive green bomber jacket"

# Multimodal understanding (needs MOONSHOT_API_KEY)
opentryon understand --model kimi-k3 --image data/model-1.jpg \
  --prompt "Describe this outfit for a product listing." --reasoning-effort high

from tryon.api import KimiUnderstandAdapter

adapter = KimiUnderstandAdapter(model="kimi-k3")
result = adapter.understand_image(
    "data/model-1.jpg",
    prompt="Describe this outfit.",
    reasoning_effort="high",
)
print(result["text"])

CLI services

opentryon <service> --model <model> [params...]
opentryon understand --help                    # list models
opentryon understand --model kimi-k3 --help    # list that model's flags

Service	Purpose	Example models
vton	Virtual try-on	flux-vto, p-image-tryon, fashn-tryon-max, …
generate	Text-to-image	nano-banana-pro, flux2-pro, gpt-image, …
edit	Image editing	nano-banana-2, flux2-flex, gpt-image, …
understand	Image/video understanding	kimi-k2.6, kimi-k3, kimi-vl, …
video-generate	Text/image-to-video	veo, sora, gemini-omni, …
bg-remove	Background removal	ben2

Models marked local need pip install opentryon[local]. Full table and flags: Unified CLI.

MCP server

cd mcp-server
pip install -r requirements.txt
python server.py                                    # stdio (Claude Desktop / Cursor)
python server.py --transport http --host 127.0.0.1 --port 8000

Tools are generated from tryon/cli/registry.py — the same registry as the CLI. See mcp-server/README.md.

Demos & notebooks

This package ships Gradio demos and Jupyter notebooks only:

python run_demo.py --name extract_garment   # also: model_swap, outfit_generator

Notebooks: notebooks/. Web UI: tryon-studio.

When contributing docs or APIs: put long tutorials in docs/, not this README. Keep README as the project front door only.
