Fireworks AI

Install

To use Fireworks AI, you need to either install pydantic-ai, or install pydantic-ai-slim with the openai optional group (as it uses an OpenAI-compatible API):

pipuv

pip install 'pydantic-ai-slim[openai]'

uv add 'pydantic-ai-slim[openai]'

Configuration

Go to Fireworks.AI and create an API key in your account settings.

You can set the FIREWORKS_API_KEY environment variable and use FireworksProvider by name:

from pydantic_ai import Agent

agent = Agent('fireworks:accounts/fireworks/models/qwq-32b')
...

Or initialise the model and provider directly:

from pydantic_ai import Agent
from pydantic_ai.models.openai import OpenAIChatModel
from pydantic_ai.providers.fireworks import FireworksProvider

model = OpenAIChatModel(
    'accounts/fireworks/models/qwq-32b',  # model library available at https://fireworks.ai/models
    provider=FireworksProvider(api_key='your-fireworks-api-key'),
)
agent = Agent(model)
...
