In this tutorial, we build a hierarchical planner agent using an open-source instruct model. We design a structured multi-agent architecture comprising a planner agent, an executor agent, and an aggregator agent, where each component plays a specialized role in solving complex tasks. We use the planner agent to decompose high-level goals into actionable steps, the executor agent to execute those steps using reasoning or Python tool execution, and the aggregator agent to synthesize results into a coherent final response. By integrating tool usage, structured planning, and iterative execution, we create a fully autonomous agent system that demonstrates how modern AI agents reason, plan, and act in a scalable and modular manner.
Qwen3.5-27B is a powerful, multimodal language model designed for versatility and efficiency. It excels in tasks requiring reasoning, coding, and visual understanding thanks to its unified vision-language foundation and efficient architecture utilizing Gated Delta Networks and sparse Mixture-of-Experts. The model supports 201 languages and boasts a native 262,144 token context window, expandable to 1,010,000.
**Key Specs:**
* **Model Type:** Causal Language Model with Vision Encoder, 27 Billion Parameters
* **Architecture:** 64 Layers, 5120 Hidden Dimension
* **Training:** Scalable Reinforcement Learning for real-world adaptability.
**Performance Highlights:** Qwen3.5-27B demonstrates strong performance across a broad spectrum of benchmarks, including: **Knowledge & Reasoning** (MMLU, C-Eval, HLE, GPQA), **Instruction Following & General Agent Capabilities** (IFEval, IFBench, BFCL-V4, TAU2-Bench), **Coding** (SWE-bench, CodeForces), **Long Context Handling** (AA-LCR, LongBench v2), **Vision-Language Understanding** (MMMU, RealWorldQA), and **Multilingual Abilities** (MMMLU, WMT24++).
**Usage & Deployment:**
The model can be served and utilized through several frameworks: **SGLang & vLLM** (for fast, high-throughput inference with features like Multi-Token Prediction), **KTransformers & Hugging Face Transformers** (offering flexibility and lightweight testing options), and a **Chat Completions API** (with OpenAI SDK examples for various input types).
**Key Considerations:**
* Operates in "thinking mode" by default (intermediate thought processes), which can be disabled.
* Well-suited for agent applications, particularly with the Qwen-Agent framework.
* Documentation provides details on API configuration and recommended sampling parameters.
