  • Free Trial: Free Trial: "New accounts receive $5 in free credits after adding a verified payment method. These credits expire 30 days after they're granted." No permanently free tier. Limits apply at the organization level and vary by model; any metric can trigger rate limiting. Dual-bucket model: uncached TPM is the primary limit, Total TPM (uncached + cached) defaults to 3x uncached. Token-bucket replenishment (continuous refill, not fixed reset). Estimated tokens include max_completion_tokens before the request runs. Exceeding returns 429 Too Many Requests indicating which bucket (uncached or total) was exceeded. Docs say exact org values are in Cloud Console > Limits and may differ from the table.
  • Developer (Pay as You Go): Docs worked example: "With a 1M uncached TPM limit, your total limit is 3M TPM. At a 70% cache hit rate, you can effectively process up to 3M total tokens per minute - 1M uncached plus up to 2M cached." Org Admins can set lower per-project, per-model limits; project quota cannot exceed the org-level quota. Pricing page labels Developer tier "For development, evaluation, and experimentation; not intended for production use."

Pro ($50)Send up to 24million tokens per day
Max ($200)Send up to 120 million tokens/day
  • Pro ($50): Marketing page copy: "enough for 3-4 hours of uninterrupted vibe coding". Plan shown as sold out; GLM 4.7 is not listed in the current Shared Inference model catalog in the docs, so treat as a legacy/unavailable plan. Free Trial on the same page: "GLM 4.7 access with limited tokens and requests" (no numbers).
  • Max ($200): Shown as "sold out" on 2026-10-17. No RPM/TPM published for Code plans.

How to raise your limits

  1. gpt-oss-120b and qwen-3.8-27b

    Purchase credits (Pay as You Go) from the Billing tab in the Cloud Console (https://cloud.cerebras.ai). "Your first purchase moves you to the Developer tier with significantly higher rate limits and no hourly or daily token caps."

  2. gpt-oss-120b and qwen-3.8-27b

    For Enterprise limits or reserved capacity, contact Cerebras (https://www.cerebras.ai/contact) or your account representative.

  3. Batch API (/v1/chat/completions) and service_tier parameter (priority, default, auto, flex) on dedicated endpoints

    Private Preview: contact Cerebras or your account representative for access.

  4. Projects (per-project, per-model quotas)

    Only Org Admins can set project rate limits: All Projects view > Projects tab > Project Settings > set per-model limits > Save.

  5. Cerebras Code (GLM 4.7)

    Upgrade to Max ($200). Page shows both plans as "sold out" as of 2026-10-17.

What the docs leave out

  • Exact per-organization limits are only shown in the logged-in Cloud Console (cloud.cerebras.ai > Limits); docs say console values reflect plan and project-level limits and can differ from the public table.
  • Enterprise numeric limits are not published (provisioned per organization).
  • No published RPH or RPD values for any tier, although the docs list RPH/RPD as measured metrics.
  • Developer tier TPH/TPD: none (explicitly not applied).
  • No published concurrency limit for real-time (non-batch) Shared Inference requests.
  • Flex service tier exact multiples not published ("several multiples of default").
  • Batch API separate rate limit values not published ("configurable").
  • Cerebras Code Free Trial token/request numbers not published, and Cerebras Code Pro/Max RPM/TPM not published; both paid plans shown as sold out.
  • Dedicated Inference model limits not published publicly.
