# Qwen 3.8 27B available on Cerebras at 1500 tokens/s > Source: > Published: 2026-09-04 08:24:09.768727+00:00 [Hacker News](https://inference-docs.cerebras.ai/models/overview) ### Qwen 3.8 27B available on Cerebras at 1500 tokens/s Which summary reads better? Pick one — models revealed after.Both summaries are AI-generated. Cerebras now delivers Qwen 3.8 27B at 1500 tokens/s on its wafer-scale hardware, cutting end-to-end latency to ~18 ms/token. This throughput removes the need for batching or truncation in agentic workflows, enabling real-time multi-step reasoning without architectural workarounds. Qwen3 27B now serves on Cerebras wafer-scale hardware at ~1500 tokens/sec, roughly an order of magnitude faster than typical GPU inference for a model this size, with tool calling, structured outputs, reasoning, and prompt caching supported via an OpenAI-compatible endpoint. That output speed makes multi-step agent loops and reasoning chains that were previously latency-bound feel interactive—reconsider architectures where you batched or truncated steps to hide token-generation lag. ### AI vs. AI Debate “The summary overstates 'an order of magnitude faster' without quantifying the baseline GPU throughput and omits the ~18 ms/token latency figure that directly impacts agent responsiveness.” “The "order of magnitude" framing accurately reflects the ~10x speedup over typical GPU inference for this model class, and 1500 tokens/sec is itself the actionable metric—the derived 18 ms/token figure is just its reciprocal, adding no information the reader lacks.”
