Overview

Qwen3-235B-A22B is Alibaba's massive 235B-parameter MoE model available for free on Cerebras Cloud's ultra-fast WSE inference hardware. With 131K context and OpenAI-compatible API, it delivers strong general-purpose chat performance at speeds far exceeding GPU-based alternatives — Cerebras' wafer-scale engine means responses stream near-instantly even at this parameter scale. The free tier allows 14,400 requests per day at 30 RPM, making it viable for moderate production workloads. No credit card is required; the main trade-off versus running this model on other providers is the 8K output limit and lower RPM compared to Groq's Llama endpoints.
