Getting started
Install
Install bridle-ai from PyPI and set up an Anthropic key.
Bridle requires Python 3.11 or newer.
Install
pip install bridle-aiThe PyPI distribution is bridle-ai; the import is bridle.
import bridle
print(bridle.__version__) # 0.1.0Set up Anthropic
v0.1.0 ships an Anthropic adapter. Set your key and call install() to register it:
import os
os.environ["ANTHROPIC_API_KEY"] = "sk-ant-..."
from bridle.models.anthropic import install
install()install() registers the Anthropic adapter as the active model client. Without it, the first step raises ConfigurationError.
Pick a model
Bridle ships zero default models. Choose a default for the process, an agent, or a single call. See model resolution for the full precedence rules.
import bridle
bridle.configure(model="claude-sonnet-4-6")Verify
A one-line smoke test:
import bridle
from bridle import step
from bridle.models.anthropic import install
install()
bridle.configure(model="claude-sonnet-4-6")
answer: str = step("reply with the single word: ready", schema=str)
print(bridle.resolve(answer)) # "ready"If this prints ready, you are set up.
