Cerebras Qwen

Cerebras Qwen: The world's fastest open-weight reasoning model, delivering frontier intelligence at up to 2,403 tokens/sec on the Wafer-Scale Engine.

This is the Cerebras-optimized deployment of the Alibaba-developed Qwen series (including Qwen3-32B and Qwen3-235B), a leading open-weight LLM. Running on the Cerebras Wafer-Scale Engine, it eliminates the latency bottleneck inherent to reasoning models: Qwen3-32B achieves real-time responsiveness, hitting speeds up to 2,403 tokens/second (Source 3). This performance—up to 60x faster than comparable GPU-based models like DeepSeek R1 (Source 3)—translates to reasoning and deep-RAG workflows completing in under a second (Source 2). We deliver this frontier-level intelligence with full 131K context support for models like Qwen3-235B, all at a fraction of the cost (less than one-tenth) of leading closed-source alternatives (Source 2).
