pip install google-adk

默认是gemini

from google.adk.agents import LlmAgent, BaseAgent

# Define individual agents
greeter = LlmAgent(name="greeter", model="gemini-2.5-flash", ...)
task_executor = LlmAgent(name="task_executor", model="gemini-2.5-flash", ...)

# Create parent agent and assign children via sub_agents
coordinator = LlmAgent(
    name="Coordinator",
    model="gemini-2.5-flash",
    description="I coordinate greetings and tasks.",
    sub_agents=[ # Assign sub_agents here
        greeter,
        task_executor
    ]
)

但是我们可以接入其他ai模型

接入claude与openai

#export OPENAI_API_KEY="YOUR_OPENAI_API_KEY"

#export ANTHROPIC_API_KEY="YOUR_ANTHROPIC_API_KEY"


from google.adk.agents import LlmAgent
from google.adk.models.lite_llm import LiteLlm

# --- Example Agent using OpenAI's GPT-4o ---
# (Requires OPENAI_API_KEY)
agent_openai = LlmAgent(
    model=LiteLlm(model="openai/gpt-4o"), # LiteLLM model string format
    name="openai_agent",
    instruction="You are a helpful assistant powered by GPT-4o.",
    # ... other agent parameters
)

# --- Example Agent using Anthropic's Claude Haiku (non-Vertex) ---
# (Requires ANTHROPIC_API_KEY)
agent_claude_direct = LlmAgent(
    model=LiteLlm(model="anthropic/claude-3-haiku-20240307"),
    name="claude_direct_agent",
    instruction="You are an assistant powered by Claude Haiku.",
    # ... other agent parameters
)

agent_openai = LlmAgent(
    model=LiteLlm(model="openai/gpt-4o"), # LiteLLM model string format
    name="openai_agent",
    instruction="You are a helpful assistant powered by GPT-4o.",
    # ... other agent parameters
)

model="openai/deepseek3", # add `openai/` prefix to model so litellm knows to route to OpenAI
api_key="sk-", # api key to your openai compatible endpoint
api_base="https://api.deepseek.com/v1",
