FireworksAI

Fireworks AI provides blazing fast inference for open-source language models. Fireworks AI is accessible through OpenAI’s SDK via full API compatibility, allowing easy and portable integration with the Strands Agents SDK using the familiar OpenAI interface.

Installation

The Strands Agents SDK provides access to Fireworks AI models through the OpenAI compatibility layer, configured as an optional dependency. To install, run:

pip install 'strands-agents[openai]' strands-agents-tools

Usage

After installing the openai package, you can import and initialize the Strands Agents’ OpenAI-compatible provider for Fireworks AI models as follows:

from strands import Agent
from strands.models.openai import OpenAIModel
from strands_tools import calculator

model = OpenAIModel(
    client_args={
        "api_key": "<FIREWORKS_API_KEY>",
        "base_url": "https://api.fireworks.ai/inference/v1",
    },
    model_id="accounts/fireworks/models/deepseek-v3p1-terminus",  # or see https://fireworks.ai/models
    params={
        "max_tokens": 5000,
        "temperature": 0.1
    }
)

agent = Agent(model=model, tools=[calculator])
agent("What is 2+2?")

Configuration

Client Configuration

The client_args configure the underlying OpenAI-compatible client. When using Fireworks AI, you must set:

api_key: Your Fireworks AI API key. Get one from the Fireworks AI Console.
base_url: https://api.fireworks.ai/inference/v1

Refer to OpenAI Python SDK GitHub for full client options.

Model Configuration

The model_config specifies which Fireworks AI model to use and any additional parameters.

Parameter	Description	Example	Options
`model_id`	Model name	`accounts/fireworks/models/deepseek-v3p1-terminus`	See Fireworks Models
`params`	Model-specific parameters	`{"max_tokens": 5000, "temperature": 0.7, "top_p": 0.9}`	API reference

Troubleshooting

`ModuleNotFoundError: No module named 'openai'`

You must install the openai dependency to use this provider:

pip install 'strands-agents[openai]'

Unexpected model behavior?

Ensure you’re using a model ID compatible with Fireworks AI (e.g., accounts/fireworks/models/deepseek-v3p1-terminus, accounts/fireworks/models/kimi-k2-instruct-0905), and your base_url is set to https://api.fireworks.ai/inference/v1.
