Cerebras Launches Qwen3-32B: Real-Time Reasoning with One of the World’s Most Powerful Open Models

SUNNYVALE, Calif.--(BUSINESS WIRE)--Cerebras today announced the launch of Qwen3-32B, one of the most advanced open-weight models in the world, now available on the Cerebras Inference Platform. Developed by Alibaba, Qwen3-32B rivals the performance of leading closed models like GPT-4.1 and DeepSeek R1—and now, for the first time, it runs on Cerebras with real-time responsiveness.

Qwen3-32B on Cerebras performs sophisticated reasoning and returns the answer in just 1.2 seconds — up to 60x faster than comparable reasoning models such as DeepSeek R1 and OpenAI o3. This is the first reasoning model on any hardware to achieve real-time reasoning. Qwen3-32B on Cerebras is the fastest reasoning model API in the world, ready to power production-grade agents, copilots, and automation workloads.

“This is the first time a world-class reasoning model—on par with DeepSeek R1 and OpenAI’s o-series — can return answers instantly,” said Andrew Feldman, CEO and co-founder of Cerebras. “It’s not just fast for a big model. It’s fast enough to reshape how real-time AI gets built.”

The First Real-Time Reasoning Model

Reasoning models are widely recognized as the most powerful class of large language models—capable of multi-step logic, tool use, and structured decision-making. But until now, they’ve come with a tradeoff: latency. Inference often takes 30–90 seconds, making them impractical for responsive user experiences.

Cerebras eliminates that bottleneck. Qwen3-32B delivers first-token latency in just one second, and completes full reasoning chains in real time. This is the only solution on the market today that combines high intelligence with real-time speed—and it’s available now.

Transparent, Scalable Pricing

Qwen3-32B is available on Cerebras with simple, production-ready pricing:

• $0.40 per million input tokens
• $0.80 per million output tokens

This is 10x cheaper than GPT-4.1, while offering comparable or better performance.

All developers receive 1 million free tokens per day, with no waitlist. Qwen3-32B is fully open-weight and Apache 2.0 licensed, and can be integrated in seconds using standard OpenAI- or Claude-compatible endpoints.

Qwen3-32B is live now on Cerebras.ai. For teams seeking to build fast, intelligent, production-ready AI systems, it is the most powerful open model you can use today.
