fireworks-ai

Fireworks.ai Python library

Fireworks.ai Python Library provides a convenient API for accessing Fireworks supported LLMs. We are targeting our API to be very similar to OpenAI's API so you can replace OpenAI usage with minimal modifications

Installation

pip install --upgrade fireworks-ai

API definitions

Please check our completion and chat completion API reference for the arguments we support and the meaning of each arguments.

Example code

List

import fireworks.client
fireworks.client.api_key = "your-key"
print(fireworks.client.Model.list())

object='list' data=[Model(id="accounts/fireworks/models/llama-v2-7b", object="model", created=0), ...]

Completion

import fireworks.client
fireworks.client.api_key = "your-key"
completion = fireworks.client.Completion.create("accounts/fireworks/models/llama-v3-8b-instruct", "Once upon a time", temperature=0.1, n=2, max_tokens=16)
print(completion)

Streaming completion

import fireworks.client
fireworks.client.api_key = "your-key"
for completion in fireworks.client.Completion.create(
    "accounts/fireworks/models/llama-v3-8b-instruct",
    prompt="Once upon a time",
    temperature=0.1,
    n=2,
    max_tokens=16
):
    print(completion)

Async completion

import asyncio
import fireworks.client
fireworks.client.api_key = "your-key"
async def main():
    response = await fireworks.client.Completion.acreate("accounts/fireworks/models/llama-v3-8b-instruct", "Once upon a time", echo=True, max_tokens=16)
    print(response.choices[0].text)
asyncio.run(main())

then run the script

$ python test.py

import fireworks.client

print(completion)
