Cohere Trial Key Limits and 'Not for Production' Error

Share
Workaround available API Updated November 14, 2026Based on 3 user reportsHow we research

Quick answer

Trial keys are free but capped at 1,000 API calls per month with low per-minute limits, and Cohere's terms do not allow production or commercial use. Upgrade to a Production key to ship.

Most likely fix: Check your usage

How to fix it

Try these in order — the most common fix is first.

  1. 1. Check your usage

    1. Sign in at dashboard.cohere.com
    2. Open the API Keys and usage views
    3. Note calls used against the 1,000 monthly limit
    Did this fix it?

  2. 2. Upgrade to a Production key

    1. Dashboard > Billing and Usage
    2. The account Owner adds billing details and applies for a Production key
    3. Replace the trial key in your environment variable (CO_API_KEY)
    Did this fix it?

  3. 3. Reduce calls while testing

    1. Cache embeddings and rerank results
    2. Batch up to 96 texts per Embed call
    3. Use a small test set instead of full datasets
