Usage

Basic Recipe Generation

To generate a basic vanilla cake recipe:

from llama_index.llms.dashscope import DashScope, DashScopeGenerationModels

# Initialize DashScope object
dashscope_llm = DashScope(model_name=DashScopeGenerationModels.QWEN_MAX)

# Generate a vanilla cake recipe
resp = dashscope_llm.complete("How to make cake?")
print(resp)

Streaming Recipe Responses

For real-time streamed responses:

responses = dashscope_llm.stream_complete("How to make cake?")
for response in responses:
    print(response.delta, end="")

Multi-Round Conversation

To have a conversation with the assistant and ask for a sugar-free cake recipe:

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

messages = [
    ChatMessage(
        role=MessageRole.SYSTEM, content="You are a helpful assistant."
    ),
    ChatMessage(role=MessageRole.USER, content="How to make cake?"),
]

# Get first round response
resp = dashscope_llm.chat(messages)
print(resp)

# Continue conversation
messages.append(
    ChatMessage(role=MessageRole.ASSISTANT, content=resp.message.content)
)
messages.append(
    ChatMessage(role=MessageRole.USER, content="How to make it without sugar?")
)

# Get second round response
resp = dashscope_llm.chat(messages)
print(resp)

Handling Sugar-Free Recipes

For sugar-free cake recipes using honey as a sweetener:

resp = dashscope_llm.complete("How to make cake without sugar?")
print(resp)
