Fireworks AI vs Together AI comparison

Quick answer
Use Fireworks AI for access to large-scale llama-v3p3-70b-instruct models optimized for instruction tasks, and Together AI for a broader range of meta-llama models with strong community support. Both offer OpenAI-compatible APIs with similar usage patterns but differ in model availability and ecosystem.

VERDICT

For cutting-edge large LLMs with instruction tuning, Fireworks AI leads; for flexibility and community-driven models, Together AI is the better choice.

Key differences

Fireworks AI specializes in large instruction-tuned models like llama-v3p3-70b-instruct, optimized for complex reasoning and instruction following. Together AI offers a broader catalog of meta-llama models, including smaller variants, with a strong community and open-source focus. Both provide OpenAI-compatible APIs but differ in model naming conventions and ecosystem maturity.

Side-by-side example

Here is how to call the chat completion endpoint for a simple prompt using each provider's OpenAI-compatible API in Python.

python
import os
from openai import OpenAI

# Fireworks AI client
fireworks_client = OpenAI(
    api_key=os.environ["FIREWORKS_API_KEY"],
    base_url="https://api.fireworks.ai/inference/v1"
)

fireworks_response = fireworks_client.chat.completions.create(
    model="accounts/fireworks/models/llama-v3p3-70b-instruct",
    messages=[{"role": "user", "content": "Explain RAG in AI."}]
)
print("Fireworks AI response:", fireworks_response.choices[0].message.content)

# Together AI client
together_client = OpenAI(
    api_key=os.environ["TOGETHER_API_KEY"],
    base_url="https://api.together.xyz/v1"
)
together_response = together_client.chat.completions.create(
    model="meta-llama/Llama-3.3-70B-Instruct-Turbo",
    messages=[{"role": "user", "content": "Explain RAG in AI."}]
)
print("Together AI response:", together_response.choices[0].message.content)
output
Fireworks AI response: Retrieval-Augmented Generation (RAG) combines retrieval of documents with generative models to improve accuracy and context.
Together AI response: RAG integrates external knowledge retrieval with language generation to provide more informed and accurate responses.

Together AI equivalent

Using Together AI with a similar prompt and model, you get a comparable instruction-following experience but with a different model namespace and endpoint.

python
from openai import OpenAI
import os

together_client = OpenAI(
    api_key=os.environ["TOGETHER_API_KEY"],
    base_url="https://api.together.xyz/v1"
)

response = together_client.chat.completions.create(
    model="meta-llama/Llama-3.3-70B-Instruct-Turbo",
    messages=[{"role": "user", "content": "Summarize the benefits of RAG."}]
)
print("Together AI summary:", response.choices[0].message.content)
output
Together AI summary: RAG enhances language models by incorporating external knowledge retrieval, improving accuracy, relevance, and reducing hallucinations.

When to use each

Use Fireworks AI when you need access to the latest large-scale instruction-tuned Llama 3.3 models optimized for enterprise-grade tasks. Choose Together AI for flexibility, community-driven models, and experimentation with various meta-llama variants.
