Cerebras Inference — free tier setup
What you get free
Ultra-fast inference (~2,600 tok/s per seed repo) on a small set of open models, no credit card. Catalog quota: "Official rate-limits page (Free Trial tier, per model, fetched 2026-07-17): gpt-oss-120b / zai-glm-4.7 / gemma-4-31b: 5 RPM, 30K TPM, 1M TPH, 1M TPD. cheahjs README (older): gpt-oss-120b: 30 requests/minute, 60,000 tokens/minute, 900 requests/hour, 1,000,000 tokens/hour, 14,400 requests/day, 1,000,000 tokens/day." Category: permanent_free — but the gotcha: the official rate-limits page now labels the tier "Free Trial" and shows 5 RPM, far below the 30 RPM the seed repos reported in June 2026. Treat the official 5 RPM as current, and watch for the tier turning into an expiring trial.

The rest of this guide — the key-obtain walkthrough, first request, the limits that will bite you, and the rotation runbook — ships with the Indie field library. What you’ve read above is the real first section, not a blurred preview; the remainder simply isn’t in this page.
