Safety Warning

⚠️ AI-driven UI automation may produce unpredictable results since it can control EVERYTHING on the screen. Please evaluate the risks carefully before use.

Model Setup

Midscene requires models with strong visual grounding capabilities (accurate UI element localization from screenshots).
Because of this, you need to prepare model access and configuration separately from skill installation.

Make sure these environment variables are available in your system. You can also define them in a .env file in the current directory, and Midscene will load them automatically:

MIDSCENE_MODEL_API_KEY="your-api-key"
MIDSCENE_MODEL_NAME="model-name"
MIDSCENE_MODEL_BASE_URL="https://..."
MIDSCENE_MODEL_FAMILY="family-identifier"

Example: Gemini (Gemini-3-Flash)

MIDSCENE_MODEL_API_KEY="your-google-api-key"
MIDSCENE_MODEL_NAME="gemini-3-flash"
MIDSCENE_MODEL_BASE_URL="https://generativelanguage.googleapis.com/v1beta/openai/"
MIDSCENE_MODEL_FAMILY="gemini"

Example: Qwen3-VL

MIDSCENE_MODEL_API_KEY="your-openrouter-api-key"
MIDSCENE_MODEL_NAME="qwen/qwen3-vl-235b-a22b-instruct"
MIDSCENE_MODEL_BASE_URL="https://openrouter.ai/api/v1"
MIDSCENE_MODEL_FAMILY="qwen3-vl"

Example: Doubao Seed 1.6

MIDSCENE_MODEL_API_KEY="your-doubao-api-key"
MIDSCENE_MODEL_NAME="doubao-seed-1-6-250615"
MIDSCENE_MODEL_BASE_URL="https://ark.cn-beijing.volces.com/api/v3"
