- format(*args: Msg | Sequence[Msg]) List[dict][源代码]
A common format strategy for chat models, which will format the input messages into a user message.
Note this strategy maybe not suitable for all scenarios, and developers are encouraged to implement their own prompt engineering strategies.
The following is an example:
prompt1 = model.format( Msg("system", "You're a helpful assistant", role="system"), Msg("Bob", "Hi, how can I help you?", role="assistant"), Msg("user", "What's the date today?", role="user") ) prompt2 = model.format( Msg("Bob", "Hi, how can I help you?", role="assistant"), Msg("user", "What's the date today?", role="user") )
The prompt will be as follows:
# prompt1 [ { "role": "system", "content": "You're a helpful assistant" }, { "role": "user", "content": ( "## Conversation History\n" "Bob: Hi, how can I help you?\n" "user: What's the date today?" ) } ] # prompt2 [ { "role": "user", "content": ( "## Conversation History\n" "Bob: Hi, how can I help you?\n" "user: What's the date today?" ) } ]
- 参数:
args (Union[Msg, Sequence[Msg]]) – The input arguments to be formatted, where each argument should be a Msg object, or a list of Msg objects. In distribution, placeholder is also allowed.
- 返回:
The formatted messages.

- format(*args: Msg | Sequence[Msg]) List[源代码]
Format the messages for DashScope Multimodal API.
The multimodal API has the following requirements:
- The roles of messages must alternate between “user” and
“assistant”.
- The message with the role “system” should be the first message
in the list.
- If the system message exists, then the second message must
have the role “user”.
The last message in the list should have the role “user”.
In each message, more than one figure is allowed.
With the above requirements, we format the messages as follows:
- If the first message is a system message, then we will keep it as
system prompt.
- We merge all messages into a conversation history prompt in a
single message with the role “user”.
- When there are multiple figures in the given messages, we will
attach it to the user message by order. Note if there are multiple figures, this strategy may cause misunderstanding for the model. For advanced solutions, developers are encouraged to implement their own prompt engineering strategies.
The following is an example:
prompt = model.format( Msg( "system", "You're a helpful assistant", role="system", url="figure1" ), Msg( "Bob", "How about this picture?", role="assistant", url="figure2" ), Msg( "user", "It's wonderful! How about mine?", role="user", image="figure3" ) )
The prompt will be as follows:
[ { "role": "system", "content": [ {"text": "You are a helpful assistant"}, {"image": "figure1"} ] }, { "role": "user", "content": [ {"image": "figure2"}, {"image": "figure3"}, { "text": ( "## Conversation History\n" "Bob: How about this picture?\n" "user: It's wonderful! How about mine?" ) }, ] } ]
备注
In multimodal API, the url of local files should be prefixed with “file://”, which will be attached in this format function.

The formatted messages.
- 返回类型:
List[dict]
- convert_url(url: str | Sequence[str] | None) List[dict][源代码]
Convert the url to the format of DashScope API. Note for local files, a prefix “file://” will be added.
- 参数:
url (Union[str, Sequence[str], None]) – A string of url of a list of urls to be converted.

A list of dictionaries with key as the type of the url and value as the url. Only “image” and “audio” are supported.
- 返回类型:
List[dict]
