Qwen Series by Alibaba

The Qwen Series is Alibaba Cloud’s family of advanced large language models (LLMs) and multimodal models (MLLMs), designed to deliver high performance across text generation, reasoning, coding, and cross-modal tasks. The latest Qwen2.5 models are pre-trained on up to 20 trillion tokens and enhanced with supervised fine-tuning (SFT) and reinforcement learning from human feedback (RLHF). With broad multilingual support, long-context capabilities, and real-time streaming outputs, the Qwen Series powers a wide range of enterprise applications and open-source use cases.

Current Models in the Qwen Series:

Large Language Models:

• Qwen2.5:
  Core pretrained and fine-tuned language models supporting up to 128K token context length. Optimized for instruction following, structured data handling (JSON/tables), multilingual reasoning, and long-form generation.

• Qwen2.5-Max:
  A large-scale Mixture-of-Experts (MoE) model trained on over 20 trillion tokens. Excels at complex reasoning, coding, and benchmark performance in tasks like Arena-Hard, GPQA-Diamond, and LiveBench.

• Qwen-Turbo:
  A high-speed, cost-efficient model offering support for up to 1M tokens. Ideal for scalable AI solutions where speed and context size matter most.

• Qwen-Plus:
  A high-performance model built for enterprise-grade use cases requiring precision, scalability, and complex logic handling (e.g., advanced coding, math, and structured outputs).

Specialized Models:

• Qwen2.5-Coder:
  A code-focused model supporting 92 programming languages, optimized for tasks like code generation, completion, repair, and debugging. Supports 128K context tokens.

• Qwen2.5-Math:
  A mathematical model trained with synthesized data for Chain-of-Thought (CoT), Program-of-Thought (PoT), and Tool-Integrated Reasoning (TIR). Excels in bilingual math problem-solving.

Multimodal Models:

• Qwen2.5-Omni:
  A real-time streaming multimodal model that processes text, images, audio, and video. Built on a Thinker-Talker architecture to deliver simultaneous generation and speech synthesis.

• Qwen-VL:
  A vision-language model supporting content generation from images, text, and bounding boxes. Handles fine-grained recognition, image comparison, math problem-solving, and visual Q&A in both English and Chinese.

• Qwen-Audio:
  A model for audio-language tasks. Accepts diverse audio inputs including speech, music, and environmental sounds. Delivers high-quality transcription and understanding without task-specific tuning.

• QVQ:
  A multimodal reasoning model optimized for science and mathematics. Combines image and video analysis with structured problem-solving capabilities.

Multimodal Generation Models:

• Wan:
  A video foundation model built on diffusion transformer architecture. Generates high-quality video through scalable pretraining and automated evaluation.

• Outfit Anyone:
  A personalized fashion model that generates outfit recommendations from text prompts, sketches, or images. Ideal for e-commerce and virtual try-on scenarios.

• Animate Anyone:
  A motion-generation model that creates realistic animations from text, image, or video inputs. Designed for gaming, avatars, and video editing applications.

Key Features Across the Series:

• Real-Time Multimodal Interaction: Qwen2.5-Omni delivers live streaming responses across text, audio, and video.

• Extended Context Handling: Models like Qwen2.5-Turbo support up to 1M tokens for ultra-long documents and interactions.

• Open Source & Customizable: Many models are licensed under Apache 2.0 and available on Hugging Face, ModelScope, and GitHub.

• Enterprise-Grade Integration: Available via Alibaba Cloud Model Studio for deployment, fine-tuning, and API access.

Example Use Cases:

• Building intelligent AI assistants with Qwen2.5 models capable of reasoning, coding, and structured output.

• Powering e-commerce personalization tools using Outfit Anyone’s clothing generation capabilities.

• Automating transcription, sound analysis, and music insights with Qwen-Audio.

• Creating realistic video avatars and animations using Animate Anyone and Wan.

• Enabling cross-modal research or education tools with QVQ’s scientific problem-solving capabilities.
