hello_world

Hello World

The simplest Google GenAI + Temporal sample: one generate_content call. The call runs as a Temporal activity, so it gets durable retries, timeouts, and crash recovery, and the Gemini credentials never enter the workflow.

What This Sample Demonstrates

• Wiring GoogleGenAIPlugin onto the worker with a real genai.Client
• Constructing a TemporalAsyncClient inside a @workflow.defn
• Calling client.models.generate_content(...) durably

Running the Sample

Prerequisites: install dependencies, set GOOGLE_API_KEY, and start a Temporal dev server (temporal server start-dev). See the suite README for details.

# Terminal 1
uv run google_genai/hello_world/run_worker.py

# Terminal 2
uv run google_genai/hello_world/run_workflow.py
