Class MiniMaxChatTemplate

java.lang.Object

smile.llm.template.MiniMaxChatTemplate

All Implemented Interfaces:

ChatTemplate

public final class MiniMaxChatTemplate
extends Object
implements ChatTemplate

Java port of the MiniMax-M3 chat_template.jinja: a system block with thinking instructions, a developer block (the user's system prompt and the tool list), then one block per turn, each introduced by ]~b] and closed by [e~[. Output is verified byte for byte against the Jinja template rendered by Hugging Face transformers.

Differences from the Jinja template, all because Message is not an arbitrary JSON object: the root role does not exist (the system prompt is always the developer block), assistant reasoning_content does not exist (reasoning is taken from <mm:think>...</mm:think> in the content), and <think>/</think> in assistant content, which is what this server returns to clients, are read as the MiniMax tags. As in the template, a system message that is not the first message is dropped.
