OpenAI Agents with Fireworks

Small demo workspace for calling Fireworks AI through OpenAI-compatible APIs and the OpenAI Agents SDK.

What's here

• openai_agents_sdk.py - OpenAI Agents SDK demo. It creates a FileLister agent with a local list_files function tool and uses Fireworks for model inference.
• response_api.py - Minimal OpenAI-compatible Responses API call against Fireworks.
• setup_venv.sh - Helper script that creates venv312 with Homebrew Python 3.12 and installs openai-agents.
• requirements.txt - Pinned Python dependencies from the working environment.
• index.html - Standalone tic-tac-toe landing page/demo. Open it directly in a browser.

Setup

From this directory:

./setup_venv.sh
source venv312/bin/activate

Or, if you already have a virtual environment:

python -m pip install -r requirements.txt

Fireworks configuration

Both Python demos default to:

https://api.fireworks.ai/inference/v1
accounts/fireworks/models/glm-5p2

Before running, add your Fireworks API key in the Python file:

FIREWORKS_API_KEY = "ADD YOUR API KEY HERE!"

For shared code, prefer reading the key from the environment instead of committing it:

export FIREWORKS_API_KEY="your_fireworks_key"

Run the demos

Agents SDK tool-calling demo:

python openai_agents_sdk.py

Simple Responses API demo:

python response_api.py

Standalone HTML page:

open index.html

Notes

The Fireworks model ID contains slashes: accounts/fireworks/models/glm-5p2. If that string is passed directly as an Agents SDK model name, the SDK may interpret accounts as a provider prefix and raise:

agents.exceptions.UserError: Unknown prefix: accounts

openai_agents_sdk.py avoids that by constructing an explicit OpenAIChatCompletionsModel with an AsyncOpenAI client pointed at the Fireworks base URL.

Security

Do not commit real API keys. If a real key was ever saved in this folder, rotate it in Fireworks.
