Python: feat: add MiniMax provider with M3 as default model by octo-patch · Pull Request #5121 · microsoft/agent-framework

octo-patch · 2026-04-06T16:50:39Z

Summary

This PR adds a new agent-framework-minimax package that integrates MiniMax's Anthropic-compatible API into the Microsoft Agent Framework, with MiniMax-M3 as the default model.

What's added

New package python/packages/minimax/agent_framework_minimax/ with:
- MiniMaxClient — fully-featured client (with middleware, telemetry, and function invocation)
- RawMiniMaxClient — lightweight client without layers
Supported models: MiniMax-M3 (default, 512K context, up to 128K output, supports image input), MiniMax-M2.7, and MiniMax-M2.7-highspeed
Uses MiniMax's Anthropic-compatible API (https://api.minimax.io/anthropic)
Filters out Anthropic-specific parameters not supported by MiniMax (betas, top_k, service_tier, etc.)
Unit tests and integration tests included

Usage

import asyncio
from agent_framework_minimax import MiniMaxClient
from agent_framework import Message

async def main():
    client = MiniMaxClient(model="MiniMax-M3")
    response = await client.get_response([Message(role="user", contents=["Hello from MiniMax!"])])
    print(response.messages[0].text)

asyncio.run(main())

`MINIMAX_API_KEY`	Yes	MiniMax API key
`MINIMAX_CHAT_MODEL`	No	Default model (defaults to `MiniMax-M3`)
`MINIMAX_BASE_URL`	No	Override base URL

+from agent_framework._tools import normalize_function_invocation_configuration
+
+USER_MESSAGE = [Message(role="user", contents=["Hello"])]
+from agent_framework.observability import ChatTelemetryLayer


Thanks! Fixed in fd69caa — moved ChatTelemetryLayer above the USER_MESSAGE assignment and removed the unused patch import.

+def minimax_unit_test_env(monkeypatch, exclude_list, override_env_param_dict):  # type: ignore
+    """Fixture to set environment variables for MiniMaxSettings."""
+    if exclude_list is None:
+        exclude_list = []
+
+    if override_env_param_dict is None:
+        override_env_param_dict = {}
+


Good catch — removed the dead None branches in fd69caa. The fixtures always return a list/dict so the checks were unreachable.

+MINIMAX_MODELS: Final[list[str]] = [
+    "MiniMax-M3",
+    "MiniMax-M2.7",
+    "MiniMax-M2.7-highspeed",
+]


Agreed — switched MINIMAX_MODELS to Final[tuple[str, ...]] backed by a tuple literal in fd69caa. Verified in and MINIMAX_MODELS[0] usages in the tests still pass.

+def test_raw_minimax_client_custom_base_url(minimax_unit_test_env: dict[str, str]) -> None:
+    """Test that RawMiniMaxClient respects a custom base_url."""
+    custom_url = "https://api.minimaxi.com/anthropic"


Replaced with https://example.com/anthropic in fd69caa — clearer placeholder that won’t be confused for a real MiniMax host.

- Move ChatTelemetryLayer import above USER_MESSAGE assignment and drop unused `patch` import (test_minimax_client.py): fixes Ruff E402 and removes dead import. - Drop dead `if exclude_list is None` / `if override_env_param_dict is None` branches in conftest.py — the fixtures always return a list/dict. - Use `Final[tuple[str, ...]]` for MINIMAX_MODELS so the constant is truly immutable (no `.append` foot-gun). - Replace `api.minimaxi.com` placeholder URL in custom base-url test with `example.com/anthropic` to make intent clearer.
