FriendliAI Achieves 3× Faster Qwen3 235B Inference Compared to vLLM Infrastructure

Infrastructure Meets Next-Gen Models

As foundation models grow even larger, the question is no longer just “how smart is the model?” but “how well can you run it in production?”.

When you’re deploying a model like Qwen3 235B, a 235-billion-parameter mixture-of-experts (MoE) model, every GPU cycle, every memory access, every expert-routing decision matters.

That’s why infrastructure is the differentiator. At FriendliAI, our platform is purpose-built to optimize large-scale MoE inference, which is exactly why we decided to benchmark Qwen3 235B and measure how we stack up against a baseline vLLM deployment on standard inference infrastructure.

In this post, you’ll learn:

• What makes Qwen3 235B a breakthrough in model architecture
• How Qwen3 235B can be utilized
• Why large MoE models present unique deployment challenges
• How FriendliAI addresses those challenges and how that shows in benchmark results
• How you can run Qwen3 235B on FriendliAI, quickly and cost-efficiently

Qwen3 235B: The Next Frontier in MoE Models

Qwen3-235B-A22B-Thinking-2507 is a Mixture-of-Experts (MoE) reasoning model optimized for deep, multi-step problem solving. With 235B total parameters and ~22B active parameters per token, it delivers strong reasoning performance while maintaining efficient inference through sparse expert activation across 128 experts.

The Thinking-2507 variant introduces refined expert routing and enhanced reasoning stability, improving structured deliberation and consistency in long-form analysis.

Benchmark Results

Across GPQA, AIME25, LiveCodeBench v6, HLE, and Arena-Hard v2, Qwen3-235B-A22B-Thinking-2507 demonstrates clear performance gains over its competitors Gemini 2.5 Pro, OpenAI o4-mini, and DeepSeek-R1-0528.

Key highlights:

• GPQA: 81.1 – +10 point improvement vs base model
• AIME25: 92.3 – Highest among all compared models
• LiveCodeBench v6: 74.1 – Strong real-world coding reasoning
• Arena-Hard v2: 79.7 – Top win rate in human-aligned evaluations
• HLE: 18.2 – Improved nuanced reasoning over base variant

The most significant gains appear in mathematical and scientific reasoning, reflecting optimized expert routing and internal reasoning calibration.

Why MoE matters

The MoE (Mixture-of-Experts) architecture enables conditional computation: for each input token, only a subset of experts are activated. This means far less computation resources are used for each request, significantly improving its memory efficiency while preserving, and sometimes even enhancing, its accuracy.

With Qwen3 235B, we see:

• 128 total experts, with 8 activated per token
• No shared experts (unlike predecessors) enabling sharper specialization
• Sophisticated routing and GQA (Grouped Query Attention) built into the architecture

In short, you're getting the capacity of a 235B-parameter model, but only the active parts are used for each token. While this is a powerful approach, it still has some challenges for production usage, which we will discuss later in this blog.

Use Cases:

Coding

Qwen3’s MoE architecture expands model capacity while keeping computation efficient by activating only a small set of experts per token. This additional capacity helps the model handle complex tasks, including coding, more effectively.

This makes it well-suited for complex software engineering environments where consistency, scalability, and speed are critical.

• Large-scale code generation and refactoring
• Multi-file dependency analysis and structural reasoning
• Automated debugging and root-cause identification
• Performance optimization and bottleneck detection
• Incremental codebase maintenance and modernization

By distributing coding responsibilities across domain-specialized experts, Qwen3 maintains high accuracy, stable output quality, and efficient resource usage, even when operating on extensive repositories or multi-language systems.

Multilingual Intelligence

Qwen3-235B’s MoE architecture is well suited for multilingual workloads, increasing capacity while keeping computation efficient by activating only a subset of experts per token. In practice, the router often learns to favor different experts for different linguistic patterns, helping the model capture language-specific syntax and nuance. This dynamic routing improves overall accuracy and efficiency for multilingual tasks.

• High-precision translation with stronger contextual fidelity
• Cross-lingual search and multilingual summarization
• Stable handling of mixed-language (code-switching) inputs
• Culturally aware responses for global customer applications

By activating only the relevant language experts, Qwen3 delivers higher linguistic accuracy with lower computational overhead, making it ideal for scalable global AI systems.

Why Deployment is Difficult

Deploying a Mixture of Experts (MoE) model at scale is inherently complex, due to several key challenges:

• Expert Routing Overhead & Uneven GPU Loads: Efficiently directing inputs to the right expert while maintaining performance can cause significant overhead, leading to uneven GPU resource utilization.
• Latency Spikes: Speed of expert switching heavily depends on inter-GPU communication, often resulting in unpredictable latency spikes that hinder real-time performance.
• Quantization & Mixed-Precision Issues: Scaling large MoE models requires careful handling of quantization and mixed-precision techniques to ensure both accuracy and efficiency, which can be tricky to manage effectively.

While many machine learning frameworks are optimized for dense models, MoE introduces an additional layer of complexity. That's where FriendliAI steps in. By providing tailored infrastructure that addresses these unique challenges, FriendliAI becomes the key enabler for deploying MoE models at scale with efficiency and reliability.
