Qwen3 High: A New Standard in Open-Weight AI
Qwen3 High is the latest breakthrough from Alibaba’s Qwen team, and it’s quickly becoming one of the most complete and versatile open-weight model suites available today. With cutting-edge performance, flexible deployment options, and advanced reasoning capabilities, Qwen3 High sets a new bar for large language models (LLMs). Best of all, you can try it now on our all-in-one AI platform: UltraGPT.pro.
What Makes Qwen3 High Special?
At its core, Qwen3 High is designed to scale across a wide range of use cases—from research-grade performance to lightweight, local deployment. The lineup includes both Mixture-of-Experts (MoE) and dense models, all released under the Apache 2.0 license, ensuring open access for developers, researchers, and organizations.
One of its most innovative features is the thinking budget—a user-controlled mechanism that allows you to decide how deeply the model reasons before answering. This gives you the flexibility to balance speed, accuracy, and cost in real time. For math, coding, and science in particular, expanding the thinking budget delivers a measurable boost in performance.
The Flagship Models
-
Qwen3-235B-A22B
-
MoE architecture with 235B parameters (22B active per step)
-
Research-grade performance across reasoning, coding, and math
-
Outperforms models like DeepSeek-R1 on benchmarks
-
Supports 128K context length
-
-
Qwen3-30B-A3B
-
Lightweight MoE with 30B total parameters (3B active)
-
Matches much larger dense models like QwQ-32B
-
Balances performance with lower inference costs
-
Also supports 128K context length
-
-
Dense Models (32B, 14B, 8B, 4B, 1.7B, 0.6B)
-
Traditional dense design where all parameters activate per step
-
Optimized for predictable latency and simpler deployments
-
Larger dense models approach general-purpose LLM performance, while smaller ones excel in mobile, embedded, or cost-sensitive use cases
-
Key Features
-
Hybrid Thinking Modes: Switch between detailed step-by-step reasoning and rapid direct responses.
-
Multilingual Mastery: Support for 119 languages and dialects, from English, Chinese, and Arabic to Persian, Swahili, and beyond.
-
Agentic Capabilities: Optimized for coding, tool use, and interactive workflows, including support for MCP and Qwen-Agent.
-
Scalable Efficiency: Thanks to the MoE architecture, large models run faster and cheaper compared to dense counterparts.
How Qwen3 High Was Built
Qwen3 High models were trained on an expanded 36 trillion-token dataset, nearly doubling the size used for Qwen2.5. The data includes web content, document extractions, and synthetic math/code examples generated by earlier Qwen models.
-
Pretraining: Three stages that built core language ability, strengthened STEM/coding/reasoning, and extended context handling up to 32K.
-
Post-training: A four-stage process combining chain-of-thought learning, reinforcement learning for reasoning, hybrid mode fusion, and general RL. This ensures models can reason deeply when needed, but also respond quickly when speed matters.
Benchmark Results
Qwen3 High models consistently compete with, and often outperform, other top-tier LLMs:
-
Reasoning (ArenaHard): Qwen3-235B scores 95.6, just shy of Gemini 2.5 Pro, and ahead of DeepSeek-R1.
-
Math (AIME 2024/25): Stronger than Grok-3, o3-mini, and DeepSeek-R1.
-
Coding (LiveCodeBench, CodeForces Elo): Beats nearly all competitors, ranking among the best available.
-
General Use (LiveBench): Reliable across real-world tasks, proving practical beyond just benchmarks.
Even smaller models like Qwen3-30B-A3B and Qwen3-4B punch above their weight, rivaling or surpassing much larger models in their respective categories.
Easy Access & Deployment
Qwen3 High is openly available and can be used in multiple ways:
-
Chat: Try it instantly at chat.qwen.ai.
-
API: Access via OpenAI-compatible endpoints (SGLang, vLLM).
-
Local Deployment: Run it on Ollama, LM Studio, llama.cpp, KTransformers, or MLX.
-
Open Weights: Download from Hugging Face, ModelScope, or Kaggle.
For developers, fine-tuning and tool integration are straightforward, making Qwen3 High one of the most flexible AI model suites released so far.
