Mixture of LoRA (MoL) Architecture
Table with columns: Adapter, Role, Description| Adapter | Role | Description |
|---|
loras/L0 | Chat | Conversational and instruction-following backbone; entry point for routing. |
loras/L1 | Agent | Personal-life agent tasks, heavy tool use, long-horizon planning, and dynamic workflows. |
loras/L2 | Coding | Code understanding, SWE tasks, terminal use, and repository workflows. |
loras/L3 | GenUI | UI4A rendering and UI-driven action. |
At runtime, L0 routes each new user request to the most suitable specialist. Ongoing reasoning and tool interactions remain within the selected LoRA, while completed work can be shared across specialists through concise summaries.

Usage
Hosted API
The hosted API is available at https://mintcn.macaron.xin/. Use the site for current model names, authentication, pricing, and rate-limit details.
For OpenAI-compatible deployments, requests follow the standard chat-completions shape:
curl https://mintcn.macaron.xin/v1/chat/completions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer <api-key>" \
-d '{
"model": "Macaron-V1-Tall",
"messages": [
{"role": "user", "content": "Create a compact dashboard UI for tracking weekly fitness goals."}
],
"temperature": 0.2,
"max_tokens": 2048
}'
This repository contains the base checkpoint at the repository root and the Macaron LoRA specialists under loras/. Load the base checkpoint with a Transformers version that supports the Qwen3.6 / Qwen3.5 MoE architecture.
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
repo_id = "mindlab-research/Macaron-V1-Tall"
tokenizer = AutoTokenizer.from_pretrained(
repo_id,
trust_remote_code=True,
)
model = AutoModelForCausalLM.from_pretrained(
repo_id,
torch_dtype=torch.bfloat16,
device_map="auto",
trust_remote_code=True,
)
model.eval()
Mixture of LoRA (MoL) Serving
For self-hosted routed serving, use the Mixture of LoRA (MoL) serving harness. The harness keeps the endpoint OpenAI-compatible while adding an L0 router, server-side LoRA metadata, and same-request switching into the selected specialist.
See the MoL serving repository for more details.
Macaron Artifacts
Macaron Artifacts is the companion local WebUI and plugin bundle for viewing Macaron sessions and GenUI output. It supports Claude Code, Codex, and Kimi Code, and can run against Macaron or another Anthropic-compatible endpoint.
The plugin includes the genui-builder skill so supported agents can produce GenUI TSX and preview the rendered artifact in the browser. See the Artifacts repository for full install, update, and provider configuration details.
