Basic Anthropic Demo - ICRL

Overview

The basic Anthropic demo mirrors the OpenAI demo but uses Claude models. It tries common Anthropic model IDs in order until one succeeds. Use it to confirm your ANTHROPIC_API_KEY is valid.

Prerequisites

ANTHROPIC_API_KEY set in your environment
Python 3.12+
icrl-py installed

Run

uv run python examples/basic_anthropic_demo.py

Optional model override (tried first if set):

MODEL=claude-sonnet-4-5 uv run python examples/basic_anthropic_demo.py

Model Fallback

If MODEL is not set, the script tries these in order:

claude-sonnet-4-5
claude-sonnet-4
claude-3-7-sonnet-latest
claude-3-5-sonnet-latest

It stops on the first model that succeeds.

Expected Output

Model: claude-sonnet-4-5
Success: True
Steps: 1
