Together.AI
Together.AI is a cloud based platform serving many open-weight LLMs such as Google’s Gemma, Meta’s Llama 2/3, Qwen, Mistral.AI’s Mistral/Mixtral, and NousResearch’s Hermes models.
Although AutoGen can be used with Together.AI’s API directly by changing
the base_url to their url, it does not cater for some differences
between messaging and it is recommended to use the Together.AI Client
class as shown in this notebook.
You will need a Together.AI account and create an API key. See their website for further details.
Features
When using this client class, messages are tailored to accommodate the specific requirements of Together.AI’s API and provide native support for function/tool calling, token usage, and accurate costs (as of June 2024).
Getting started
First, you need to install the pyautogen package to use AutoGen with
the Together.AI API library.
pip install pyautogen[together]
Together.AI provides a large number of models to use, included some below. See the list of models here.
See the sample OAI_CONFIG_LIST below showing how the Together.AI
client class is used by specifying the api_type as together.
[
{
"model": "gpt-35-turbo",
"api_key": "your OpenAI Key goes here",
},
{
"model": "gpt-4-vision-preview",
"api_key": "your OpenAI Key goes here",
},
{
"model": "dalle",
"api_key": "your OpenAI Key goes here",
},
{
"model": "google/gemma-7b-it",
"api_key": "your Together.AI API Key goes here",
"api_type": "together"
},
{
"model": "codellama/CodeLlama-70b-Instruct-hf",
"api_key": "your Together.AI API Key goes here",
"api_type": "together"
},
{
"model": "meta-llama/Llama-2-13b-chat-hf",
"api_key": "your Together.AI API Key goes here",
"api_type": "together"
},
{
"model": "Qwen/Qwen2-72B-Instruct",
"api_key": "your Together.AI API Key goes here",
"api_type": "together"
}
]
As an alternative to the api_key key and value in the config, you can
set the environment variable TOGETHER_API_KEY to your Together.AI key.
Linux/Mac:
export TOGETHER_API_KEY="your_together_ai_api_key_here"
Windows:
set TOGETHER_API_KEY=your_together_ai_api_key_here
API parameters
The following Together.AI parameters can be added to your config. See this link for further information on their purpose, default values, and ranges.
- max_tokens (integer)
- temperature (float)
- top_p (float)
- top_k (integer)
- repetition_penalty (float)
- frequency_penalty (float)
- presence_penalty (float)
- min_p (float)
- safety_model (string - moderation models here)
Example:
[
{
"model": "microsoft/phi-2",
"api_key": "your Together.AI API Key goes here",
"api_type": "together",
"max_tokens": 1000,
"stream": False,
"temperature": 1,
"top_p": 0.8,
"top_k": 50,
"repetition_penalty": 0.5,
"presence_penalty": 1.5,
"frequency_penalty": 1.5,
"min_p": 0.2,
"safety_model": "Meta-Llama/Llama-Guard-7b"
}
]
Two-Agent Coding Example
In this example, we run a two-agent chat with an AssistantAgent (primarily a coding agent) to generate code to count the number of prime numbers between 1 and 10,000 and then it will be executed.
We’ll use Mistral’s Mixtral-8x7B instruct model which is suitable for coding.
import os
config_list = [
{
# Let's choose the Mixtral 8x7B model
"model": "mistralai/Mixtral-8x7B-Instruct-v0.1",
# Provide your Together.AI API key here or put it into the TOGETHER_API_KEY environment variable.
"api_key": os.environ.get("TOGETHER_API_KEY"),
# We specify the API Type as 'together' so it uses the Together.AI client class
"api_type": "together",
"stream": False,
}
]
Importantly, we have tweaked the system message so that the model doesn’t return the termination keyword, which we’ve changed to FINISH, with the code block.
from pathlib import Path
from autogen import AssistantAgent, UserProxyAgent
from autogen.coding import LocalCommandLineCodeExecutor
# Setting up the code executor
workdir = Path("coding")
workdir.mkdir(exist_ok=True)
code_executor = LocalCommandLineCodeExecutor(work_dir=workdir)
# Setting up the agents
# The UserProxyAgent will execute the code that the AssistantAgent provides
user_proxy_agent = UserProxyAgent(
name="User",
code_execution_config={"executor": code_executor},
is_termination_msg=lambda msg: "FINISH" in msg.get("content"),
)
system_message = """You are a helpful AI assistant who writes code and the user executes it.
Solve tasks using your coding and language skills.
In the following cases, suggest python code (in a python coding block) for the user to execute.
Solve the task step by step if you need to. If a plan is not provided, explain your plan first. Be clear which step uses code, and which step uses your language skill.
When using code, you must indicate the script type in the code block. The user cannot provide any other feedback or perform any other action beyond executing the code you suggest. The user can't modify your code. So do not suggest incomplete code which requires users to modify. Don't use a code block if it's not intended to be executed by the user.
Don't include multiple code blocks in one response. Do not ask users to copy and paste the result. Instead, use 'print' function for the output when relevant. Check the execution result returned by the user.
If the result indicates there is an error, fix the error and output the code again. Suggest the full code instead of partial code or code changes. If the error can't be fixed or if the task is not solved even after the code is executed successfully, analyze the problem, revisit your assumption, collect additional info you need, and think of a different approach to try.
When you find an answer, verify the answer carefully. Include verifiable evidence in your response if possible.
IMPORTANT: Wait for the user to execute your code and then you can reply with the word "FINISH". DO NOT OUTPUT "FINISH" after your code block."""
# The AssistantAgent, using Together.AI's Code Llama model, will take the coding request and return code

from .autonotebook import tqdm as notebook_tqdm
# Start the chat, with the UserProxyAgent asking the AssistantAgent the message
chat_result = user_proxy_agent.initiate_chat(
assistant_agent,
message="Provide code to count the number of prime numbers from 1 to 10000.",
)
User (to Together Assistant):
Provide code to count the number of prime numbers from 1 to 10000.

Together Assistant (to User):
```python
def is_prime(n):
if n <= 1:
return False
for i in range(2, int(n**0.5) + 1):
if n % i == 0:
return False
return True
count = 0
for num in range(1, 10001):
if is_prime(num):
count += 1
print(count)
```
This code defines a helper function `is_prime(n)` to check if a number `n` is prime. It then iterates through numbers from 1 to 10000, checks if each number is prime using the helper function, and increments a counter if it is. Finally, it prints the total count of prime numbers found.

Tool Call Example
In this example, instead of writing code, we will have two agents playing chess against each other using tool calling to make moves.
Important:
We are utilising a parameter that’s supported by certain client classes,
such as this one, called hide_tools. This parameter will hide the
tools from the Together.AI response creation call if tools have already
been executed and this helps minimise the chance of the LLM choosing a
tool when we don’t need it to.
Here we are using if_all_run, indicating that we want to hide the
tools if all the tools have already been run. This will apply in each
nested chat, so each time a player takes a turn it will aim to run both
functions and then finish with a text response so we can hand control
back to the other player.
config_list = [
{
# Let's choose Meta's CodeLlama 34b instruct model which supports function calling through the Together.AI API
"model": "mistralai/Mixtral-8x7B-Instruct-v0.1",
"api_key": os.environ.get("TOGETHER_API_KEY"),
"api_type": "together",
"hide_tools": "if_all_run",
}
]
First install the chess package by running the following command:
! pip install chess
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: chess in /home/autogen/.local/lib/python3.11/site-packages (1.10.0)
Write the function for making a move.
import random
import chess
import chess.svg
from IPython.display import display
from typing_extensions import Annotated
board = chess.Board()
def make_move() -> Annotated[str, "A move in UCI format"]:
moves = list(board.legal_moves)
move = random.choice(moves)
board.push(move)
# Display the board.
display(chess.svg.board(board, size=400))
return str(move)
Let’s create the agents. We have three different agents: -
player_white is the agent that plays white. - player_black is the
agent that plays black. - board_proxy is the agent that moves the
pieces on the board.
from autogen import ConversableAgent, register_function
player_white = ConversableAgent(
name="Player White",
system_message="You are a chess player and you play as white. " "Always call make_move() to make a move",
llm_config={"config_list": config_list, "cache_seed": None},
)
player_black = ConversableAgent(
name="Player Black",
system_message="You are a chess player and you play as black. " "Always call make_move() to make a move",
llm_config={"config_list": config_list, "cache_seed": None},
)
board_proxy = ConversableAgent(
name="Board Proxy",
llm_config=False,
# The board proxy will only respond to the make_move function.
is_termination_msg=lambda msg: "tool_calls" not in msg,
)
Register tools for the agents. See the tutorial chapter on tool use for more information.
register_function(
make_move,
caller=player_white,
executor=board_proxy,
name="make_move",
description="Make a move.",
)
register_function(
make_move,
caller=player_black,
executor=board_proxy,
name="make_move",
description="Make a move.",
)
/home/autogen/autogen/autogen/agentchat/conversable_agent.py:2408: UserWarning: Function 'make_move' is being overridden.
warnings.warn(f"Function '{name}' is being overridden.", UserWarning)
Register nested chats for the player agents. Nested chats allows each player agent to chat with the board proxy agent to make a move, before communicating with the other player agent. See the nested chats tutorial chapter for more information.
player_white.register_nested_chats(
trigger=player_black,
chat_queue=[
{
"sender": board_proxy,
"recipient": player_white,
}
],
)
player_black.register_nested_chats(
trigger=player_white,
chat_queue=[
{
"sender": board_proxy,
"recipient": player_black,
}
],
)
Clear the board and start the chess game.
# Clear the board.
board = chess.Board()
chat_result = player_white.initiate_chat(
player_black,
message="Let's play chess! Your move.",
max_turns=4,
)
Player White (to Player Black):
Let's play chess! Your move.
