Together.AI

Together.AI 是一个基于云的平台，服务于许多开放权重的LLMs，例如Google的Gemma，Meta的Llama 2/3，Qwen，Mistral.AI的Mistral/Mixtral，以及NousResearch的Hermes模型。

尽管通过更改base_url为他们的URL可以直接将AutoGen与Together.AI的API一起使用，但它并未处理消息传递之间的一些差异，因此建议使用如本笔记本中所示的Together.AI Client类。

您将需要一个Together.AI账户并创建一个API密钥。请参阅他们的网站了解更多详情。

功能

当使用此客户端类时，消息会根据Together.AI的API的具体需求进行定制，并原生支持函数/工具调用、令牌使用和准确的成本计算（截至2024年6月）。

入门

首先，您需要安装autogen-agentchat~=0.2包，以便使用AutoGen与Together.AI API库。

pip install autogen-agentchat[together]~=0.2

Together.AI 提供了大量可使用的模型，其中一些列举如下。查看完整模型列表。

请参阅下面的示例 OAI_CONFIG_LIST，展示了如何通过指定 api_type 为 together 来使用 Together.AI 客户端类。

[
    {
        "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"
    }
]

作为配置中api_key键和值的替代方案，您可以将环境变量TOGETHER_API_KEY设置为您的Together.AI密钥。

Linux/Mac:

export TOGETHER_API_KEY="your_together_ai_api_key_here"

Windows:

set TOGETHER_API_KEY=your_together_ai_api_key_here

API参数

以下Together.AI参数可以添加到您的配置中。有关其用途、默认值和范围的更多信息，请参见此链接。

max_tokens (整数)
temperature (float)
top_p (float)
top_k (整数)
repetition_penalty (float)
frequency_penalty (float)
presence_penalty (float)
min_p (float)
safety_model (字符串 - moderation models here)

示例：

[
    {
        "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"
    }
]

双代理编码示例

在这个示例中，我们运行了一个双代理聊天，其中包含一个AssistantAgent（主要是一个编码代理）来生成代码，用于计算1到10,000之间的质数数量，然后执行该代码。

我们将使用Mistral的Mixtral-8x7B指令模型，该模型适合用于编码。

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,
    }
]

重要的是，我们已经调整了系统消息，以便模型不会返回终止关键字，我们已将其更改为 FINISH，与代码块一起。

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
assistant_agent = AssistantAgent(
    name="Together Assistant",

  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(

)

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.

工具调用示例

在这个示例中，我们不会编写代码，而是让两个代理使用工具调用进行移动，彼此下棋。

重要：

我们正在利用某些客户端类支持的参数，例如这个名为hide_tools的参数。如果工具已经执行，此参数将从Together.AI的响应创建调用中隐藏工具，这有助于最小化在不需要时LLM选择工具的可能性。

这里我们使用了if_all_run，表示如果所有工具都已运行，我们希望隐藏这些工具。这将适用于每个嵌套的聊天，因此每次玩家轮到时，它将尝试运行两个函数，然后以文本响应结束，以便我们可以将控制权交还给另一个玩家。

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",
    }
]

首先通过运行以下命令安装chess包：

! 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)

编写做出移动的函数。

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)

让我们创建代理。我们有三种不同的代理： - player_white 是执白棋的代理。 - player_black 是执黑棋的代理。 - board_proxy 是在棋盘上移动棋子的代理。

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,
)

为代理注册工具。有关更多信息，请参阅工具使用教程章节。

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)

为玩家代理注册嵌套聊天。嵌套聊天允许每个玩家代理与棋盘代理聊天以做出移动，然后再与其他玩家代理进行通信。更多信息请参阅嵌套聊天教程章节。

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,
        }
    ],
)

清空棋盘并开始棋局。

# 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.
