VERDICT

Should I use Cerebras?

World's fastest AI inference on wafer-scale chips; up to 30x faster than GPUs. - cerebras.ai

Depends. Buy only if you are latency-bound — real-time voice or coding agents — and can live with open-weight models and rate limits. Skip it if you need GPT/Claude-class models, guaranteed capacity, or a safe default provider.
