Table read on · inference-docs.cerebras.ai
Cerebras is listed here because older articles still describe a free tier of one million tokens a day. Its rate-limits page now describes a Free Trial: $5 in credits, granted after a verified payment method is added, expiring 30 days later.
During the trial the published limits are 5 requests per minute and one million tokens per day on gpt-oss-120b and qwen-3.8-27b.
