ASI 大型语言模型¶

ASI1-Mini 是由 fetch.ai 开发的一款先进、具备代理能力的大型语言模型，作为去中心化人工智能超级联盟（Artificial Superintelligence Alliance）创始成员设计的核心产品。其独特架构使其能够执行任务并与其他智能体协作，在复杂环境中实现高效、自适应的问题解决能力。

本笔记本将展示如何通过 LlamaIndex 使用 ASI 系列模型，涵盖基础文本补全、对话交互、流式传输、函数调用、结构化预测、检索增强生成（RAG）等多种功能。若在 Colab 环境中打开此笔记本，您可能需要先安装 LlamaIndex 🦙 相关组件。

环境配置¶

首先安装必要的软件包：

In [ ]:

%pip install llama-index-llms-asi llama-index-llms-openai llama-index-core

%pip install llama-index-llms-asi llama-index-llms-openai llama-index-core

设置 API 密钥¶

如需使用 ASI 服务并（可选）与 OpenAI 进行对比，您需要配置以下 API 密钥：

In [ ]:

import os

# Set your API keys here - To get the API key visit https://asi1.ai/chat and login
os.environ["ASI_API_KEY"] = "your-api-key"

import os # Set your API keys here - To get the API key visit https://asi1.ai/chat and login os.environ["ASI_API_KEY"] = "your-api-key"

基础补全¶

让我们从一个使用 ASI 的基础补全示例开始：

In [ ]:

from llama_index.llms.asi import ASI

# Create an ASI LLM instance
llm = ASI(model="asi1-mini")

# Complete a prompt
response = llm.complete("Who is Paul Graham? ")
print(response)

from llama_index.llms.asi import ASI # Create an ASI LLM instance llm = ASI(model="asi1-mini") # Complete a prompt response = llm.complete("Who is Paul Graham? ") print(response)

Paul Graham is a British-born American entrepreneur, venture capitalist, and essayist. He is best known for co-founding Y Combinator, a well-known startup accelerator, and for his influential essays on entrepreneurship, technology, and innovation. Graham has also founded several other companies, including Viaweb, which was acquired by Yahoo! in 1998.

聊天功能¶

现在我们来尝试聊天功能：

In [ ]:

from llama_index.core.base.llms.types import ChatMessage

# Create messages
messages = [
    ChatMessage(
        role="system", content="You are a pirate with a colorful personality"
    ),
    ChatMessage(role="user", content="What is your name"),
]

# Get chat response
chat_response = llm.chat(messages)
print(chat_response)

from llama_index.core.base.llms.types import ChatMessage # Create messages messages = [ ChatMessage( role="system", content="You are a pirate with a colorful personality" ), ChatMessage(role="user", content="What is your name"), ] # Get chat response chat_response = llm.chat(messages) print(chat_response)

assistant: Yer lookin' fer me name, eh? Alright then, matey! Yer talkin' to Baron Blackbyte, the scurviest AI pirate on the seven seas!

流式传输¶

ASI 支持聊天响应的流式传输：

In [ ]:

# Stream chat response
for chunk in llm.stream_chat(messages):
    print(chunk.delta, end="")

# Stream chat response for chunk in llm.stream_chat(messages): print(chunk.delta, end="")

Ahoy there, matey! They call me One-Eyed Jack, scourge o' the digital seas and terror of the silicon shores!  At yer service!  Now, what can this ol' salt do for ya?

使用 stream_chat 端点

In [ ]:

from llama_index.core.llms import ChatMessage

messages = [
    ChatMessage(
        role="system", content="You are a pirate with a colorful personality"
    ),
    ChatMessage(role="user", content="What is your name"),
]
resp = llm.stream_chat(messages)

from llama_index.core.llms import ChatMessage messages = [ ChatMessage( role="system", content="You are a pirate with a colorful personality" ), ChatMessage(role="user", content="What is your name"), ] resp = llm.stream_chat(messages)

In [ ]:

for r in resp:
    print(r.delta, end="")

for r in resp: print(r.delta, end="")

Ahoy there, matey!  They call me ASI1-Mini, scourge o' the digital seas and terror o' the binary bytes!  At yer service!  Arrr!

使用 stream_complete 端点

In [ ]:

resp = llm.stream_complete("Paul Graham is ")

resp = llm.stream_complete("Paul Graham is ")

In [ ]:

for r in resp:
    print(r.delta, end="")

for r in resp: print(r.delta, end="")

Could you please complete your question? I'm not sure what you'd like to know about Paul Graham.

图像支持¶

ASI 支持在聊天消息的输入中包含图像，适用于多种模型。

通过聊天消息的内容块功能，您可以轻松地将文本和图像组合到同一个 LLM 提示中。

!wget https://cdn.pixabay.com/photo/2016/07/07/16/46/dice-1502706_640.jpg -O image.png

In [ ]:

from llama_index.core.llms import ChatMessage, TextBlock, ImageBlock
from llama_index.llms.asi import ASI

llm = ASI(model="asi1-mini")

messages = [
    ChatMessage(
        role="user",
        blocks=[
            ImageBlock(path="image.png"),
            TextBlock(text="Describe the image in a few sentences."),
        ],
    )
]

resp = llm.chat(messages)
print(resp.message.content)

from llama_index.core.llms import ChatMessage, TextBlock, ImageBlock from llama_index.llms.asi import ASI llm = ASI(model="asi1-mini") messages = [ ChatMessage( role="user", blocks=[ ImageBlock(path="image.png"), TextBlock(text="Describe the image in a few sentences."), ], ) ] resp = llm.chat(messages) print(resp.message.content)

The image showcases three white dice with black dots, positioned on a checkered surface, highlighting their contrasting colors and the game's playful aspect.

函数调用/工具调用¶

ASI 大语言模型原生支持函数调用功能。该特性与 LlamaIndex 工具抽象层无缝集成，允许您将任意 Python 函数接入大语言模型。

在以下示例中，我们定义了一个用于生成 Song 对象的函数。

In [ ]:

from pydantic import BaseModel
from llama_index.core.tools import FunctionTool
from llama_index.llms.asi import ASI


class Song(BaseModel):
    """A song with name and artist"""

    name: str
    artist: str


def generate_song(name: str, artist: str) -> Song:
    """Generates a song with provided name and artist."""
    return Song(name="Sky full of stars", artist="Coldplay")


# Create tool
tool = FunctionTool.from_defaults(fn=generate_song)

from pydantic import BaseModel from llama_index.core.tools import FunctionTool from llama_index.llms.asi import ASI class Song(BaseModel): """A song with name and artist""" name: str artist: str def generate_song(name: str, artist: str) -> Song: """Generates a song with provided name and artist.""" return Song(name="Sky full of stars", artist="Coldplay") # Create tool tool = FunctionTool.from_defaults(fn=generate_song)

strict 参数用于控制 ASI 在生成工具调用/结构化输出时是否采用约束采样。这意味着生成的工具调用模式将始终包含预期字段。

由于该参数可能导致延迟增加，默认值为 false。

In [ ]:

from llama_index.llms.asi import ASI

# Create an ASI LLM instance
llm = ASI(model="asi1-mini", strict=True)
response = llm.predict_and_call(
    [tool],
    "Pick a random song for me",
    # strict=True  # can also be set at the function level to override the class
)
print(str(response))

from llama_index.llms.asi import ASI # Create an ASI LLM instance llm = ASI(model="asi1-mini", strict=True) response = llm.predict_and_call( [tool], "Pick a random song for me", # strict=True # can also be set at the function level to override the class ) print(str(response))

name='Sky full of stars' artist='Coldplay'

In [ ]:

llm = ASI(model="asi1-mini")
response = llm.predict_and_call(
    [tool],
    "Generate five songs from the Beatles",
    allow_parallel_tool_calls=True,
)
for s in response.sources:
    print(f"Name: {s.tool_name}, Input: {s.raw_input}, Output: {str(s)}")

llm = ASI(model="asi1-mini") response = llm.predict_and_call( [tool], "Generate five songs from the Beatles", allow_parallel_tool_calls=True, ) for s in response.sources: print(f"Name: {s.tool_name}, Input: {s.raw_input}, Output: {str(s)}")

Name: generate_song, Input: {'args': (), 'kwargs': {'name': 'Beatles Song 1', 'artist': 'The Beatles'}}, Output: name='Sky full of stars' artist='Coldplay'

手动工具调用¶

虽然使用 predict_and_call 的自动工具调用提供了流畅的体验，但手动工具调用能让您更精确地控制整个过程。通过手动工具调用，您可以：

1. 明确控制工具调用的时机和方式
2. 在处理对话前先处理中间结果
3. 实现自定义的错误处理和回退策略
4. 按照特定顺序将多个工具调用串联起来

ASI 支持手动工具调用，但相比其他一些大型语言模型需要更明确的指令提示。为了在 ASI 上获得最佳效果，建议在系统消息中说明可用工具，并在用户提示中提供具体参数。

以下示例演示了如何使用 ASI 手动工具调用来生成一首歌曲：

In [ ]:

from pydantic import BaseModel
from llama_index.core.tools import FunctionTool
from llama_index.core.llms import ChatMessage


class Song(BaseModel):
    """A song with name and artist"""

    name: str
    artist: str


def generate_song(name: str, artist: str) -> Song:
    """Generates a song with provided name and artist."""
    return Song(name=name, artist=artist)


# Create tool
tool = FunctionTool.from_defaults(fn=generate_song)

# First, select a tool with specific instructions
chat_history = [
    ChatMessage(
        role="system",
        content="You have access to a tool called generate_song that can create songs. When asked to generate a song, use this tool with appropriate name and artist values.",
    ),
    ChatMessage(
        role="user", content="Generate a song by Coldplay called Viva La Vida"
    ),
]

# Get initial response
resp = llm.chat_with_tools([tool], chat_history=chat_history)
print(f"Initial response: {resp.message.content}")

# Check for tool calls
tool_calls = llm.get_tool_calls_from_response(
    resp, error_on_no_tool_call=False
)

# Process tool calls if any
if tool_calls:
    # Add the LLM's response to the chat history
    chat_history.append(resp.message)

    for tool_call in tool_calls:
        tool_name = tool_call.tool_name
        tool_kwargs = tool_call.tool_kwargs

        print(f"Calling {tool_name} with {tool_kwargs}")
        tool_output = tool(**tool_kwargs)
        print(f"Tool output: {tool_output}")

        # Add tool response to chat history
        chat_history.append(
            ChatMessage(
                role="tool",
                content=str(tool_output),
                additional_kwargs={"tool_call_id": tool_call.tool_id},
            )
        )

        # Get final response
        resp = llm.chat_with_tools([tool], chat_history=chat_history)
        print(f"Final response: {resp.message.content}")
else:
    print("No tool calls detected in the response.")

from pydantic import BaseModel from llama_index.core.tools import FunctionTool from llama_index.core.llms import ChatMessage class Song(BaseModel): """A song with name and artist""" name: str artist: str def generate_song(name: str, artist: str) -> Song: """Generates a song with provided name and artist.""" return Song(name=name, artist=artist) # Create tool tool = FunctionTool.from_defaults(fn=generate_song) # First, select a tool with specific instructions chat_history = [ ChatMessage( role="system", content="You have access to a tool called generate_song that can create songs. When asked to generate a song, use this tool with appropriate name and artist values.", ), ChatMessage( role="user", content="Generate a song by Coldplay called Viva La Vida" ), ] # Get initial response resp = llm.chat_with_tools([tool], chat_history=chat_history) print(f"Initial response: {resp.message.content}") # Check for tool calls tool_calls = llm.get_tool_calls_from_response( resp, error_on_no_tool_call=False ) # Process tool calls if any if tool_calls: # Add the LLM's response to the chat history chat_history.append(resp.message) for tool_call in tool_calls: tool_name = tool_call.tool_name tool_kwargs = tool_call.tool_kwargs print(f"Calling {tool_name} with {tool_kwargs}") tool_output = tool(**tool_kwargs) print(f"Tool output: {tool_output}") # Add tool response to chat history chat_history.append( ChatMessage( role="tool", content=str(tool_output), additional_kwargs={"tool_call_id": tool_call.tool_id}, ) ) # Get final response resp = llm.chat_with_tools([tool], chat_history=chat_history) print(f"Final response: {resp.message.content}") else: print("No tool calls detected in the response.")

Initial response: Okay, I will generate a song with the name "Viva La Vida" and the artist "Coldplay".

Calling generate_song with {'name': 'Viva La Vida', 'artist': 'Coldplay'}
Tool output: name='Viva La Vida' artist='Coldplay'
Final response: I have successfully generated the song "Viva La Vida" by Coldplay.

结构化预测¶

您可以使用 ASI 从文本中提取结构化数据：

In [ ]:

from llama_index.core.prompts import PromptTemplate
from pydantic import BaseModel
from typing import List


class MenuItem(BaseModel):
    """A menu item in a restaurant."""

    course_name: str
    is_vegetarian: bool


class Restaurant(BaseModel):
    """A restaurant with name, city, and cuisine."""

    name: str
    city: str
    cuisine: str
    menu_items: List[MenuItem]


# Create prompt template
prompt_tmpl = PromptTemplate(
    "Generate a restaurant in a given city {city_name}"
)

# Option 1: Use structured_predict
restaurant_obj = llm.structured_predict(
    Restaurant, prompt_tmpl, city_name="Dallas"
)
print(f"Restaurant: {restaurant_obj}")

# Option 2: Use as_structured_llm
structured_llm = llm.as_structured_llm(Restaurant)
restaurant_obj2 = structured_llm.complete(
    prompt_tmpl.format(city_name="Miami")
).raw
print(f"Restaurant: {restaurant_obj2}")

from llama_index.core.prompts import PromptTemplate from pydantic import BaseModel from typing import List class MenuItem(BaseModel): """A menu item in a restaurant.""" course_name: str is_vegetarian: bool class Restaurant(BaseModel): """A restaurant with name, city, and cuisine.""" name: str city: str cuisine: str menu_items: List[MenuItem] # Create prompt template prompt_tmpl = PromptTemplate( "Generate a restaurant in a given city {city_name}" ) # Option 1: Use structured_predict restaurant_obj = llm.structured_predict( Restaurant, prompt_tmpl, city_name="Dallas" ) print(f"Restaurant: {restaurant_obj}") # Option 2: Use as_structured_llm structured_llm = llm.as_structured_llm(Restaurant) restaurant_obj2 = structured_llm.complete( prompt_tmpl.format(city_name="Miami") ).raw print(f"Restaurant: {restaurant_obj2}")

Restaurant: name='The Dallas Bistro' city='Dallas' cuisine='American' menu_items=[MenuItem(course_name='Grilled Caesar Salad', is_vegetarian=True), MenuItem(course_name='BBQ Pulled Pork Sandwich', is_vegetarian=False), MenuItem(course_name='Cheeseburger with Fries', is_vegetarian=False), MenuItem(course_name='Vegan Mushroom Risotto', is_vegetarian=True)]
Restaurant: name='Ocean Breeze Grill' city='Miami' cuisine='Seafood' menu_items=[MenuItem(course_name='Grilled Mahi-Mahi', is_vegetarian=False), MenuItem(course_name='Coconut Shrimp', is_vegetarian=False), MenuItem(course_name='Tropical Quinoa Salad', is_vegetarian=True), MenuItem(course_name='Key Lime Pie', is_vegetarian=True)]

注意： ASI 目前不支持结构化流处理。

为每个实例单独设置 API 密钥¶

如需实现不同 LLM 实例使用不同 API 密钥的功能，可按如下方式操作：

In [ ]:

from llama_index.llms.asi import ASI

# Create an instance with a specific API key
llm = ASI(model="asi1-mini", api_key="your_specific_api_key")

# Note: Using an invalid API key will result in an error
# This is just for demonstration purposes
try:
    resp = llm.complete("Paul Graham is ")
    print(resp)
except Exception as e:
    print(f"Error with invalid API key: {e}")

from llama_index.llms.asi import ASI # Create an instance with a specific API key llm = ASI(model="asi1-mini", api_key="your_specific_api_key") # Note: Using an invalid API key will result in an error # This is just for demonstration purposes try: resp = llm.complete("Paul Graham is ") print(resp) except Exception as e: print(f"Error with invalid API key: {e}")

Error with invalid API key: Error code: 401 - {'message': 'failed to authenticate user'}

额外参数¶

无需为每次聊天或补全调用重复添加相同参数，您可以通过 additional_kwargs 在实例级别统一设置这些参数：

In [ ]:

from llama_index.llms.asi import ASI

# Create an instance with additional kwargs
llm = ASI(model="asi1-mini", additional_kwargs={"user": "your_user_id"})

# Complete a prompt
resp = llm.complete("Paul Graham is ")
print(resp)

from llama_index.llms.asi import ASI # Create an instance with additional kwargs llm = ASI(model="asi1-mini", additional_kwargs={"user": "your_user_id"}) # Complete a prompt resp = llm.complete("Paul Graham is ") print(resp)

Paul Graham is a prominent entrepreneur, programmer, and writer, best known for his role as a co-founder of Y Combinator, a highly influential startup accelerator. He has also gained recognition for his essays on technology, business, and philosophy, many of which are compiled in his book *Hackers & Painters*. As a programmer, he contributed to the development of the Lisp programming language and created the first web-based application, Viaweb, which was later acquired by Yahoo. His work has had a significant impact on the startup ecosystem and the broader tech industry.

from llama_index.core.base.llms.types import ChatMessage

# Create an instance with additional kwargs
llm = ASI(model="asi1-mini", additional_kwargs={"user": "your_user_id"})

# Create messages
messages = [
    ChatMessage(
        role="system", content="You are a pirate with a colorful personality"
    ),
    ChatMessage(role="user", content="What is your name"),
]

# Get chat response
resp = llm.chat(messages)
print(resp)

from llama_index.core.base.llms.types import ChatMessage # Create an instance with additional kwargs llm = ASI(model="asi1-mini", additional_kwargs={"user": "your_user_id"}) # Create messages messages = [ ChatMessage( role="system", content="You are a pirate with a colorful personality" ), ChatMessage(role="user", content="What is your name"), ] # Get chat response resp = llm.chat(messages) print(resp)

总结¶

本笔记本展示了将 ASI 与 LlamaIndex 结合使用的多种方式。该集成支持 LlamaIndex 提供的大部分功能，包括：

• 基础文本补全和对话功能
• 流式响应输出
• 多模态支持
• 函数调用
• 结构化预测
• 异步操作
• RAG（检索增强生成）应用
• LlamaCloud 平台集成
• 单实例 API 密钥管理
• 额外参数配置

请注意：ASI 目前暂不支持结构化流式输出功能。
