Cohere Trial Key Pricing and Limits Summary for Free Trial
This article organizes and explains the pricing structure and usage limitations of Cohere’s Trial key based on official information as of September 2025.
To conclude first, Cohere’s Trial key is completely free to use.
However, since it’s intended for evaluation and trial purposes, several limitations are imposed. For production environment usage, you’ll need a “Production API key” with pay-as-you-go pricing based on token count.
| Item | Details |
|---|---|
| Usage Fee | Free. No charges for Trial key usage. |
| Limitations (Usage/Calls) | Monthly call limits and per-minute call limits (rate limits) are set. Details explained below. |
| Production key | Key for full-scale usage. Charged based on input/output token count. Pricing varies by model. |
The free Trial key has the following limitations. For personal development and technical validation, these are often sufficient.
You can make up to 1,000 API calls per month across all endpoints (Chat, Embed, Rerank, etc.) combined.
Each API endpoint has rate limits set for calls per minute.
| API | Limit |
|---|---|
| Chat | 20 calls / minute |
| Embed (Text) | 100 calls / minute |
| Embed (Image) | 5 calls / minute |
| Rerank | 10 calls / minute |
| Tokenize | 100 calls / minute |
| Classify | 100 calls / minute |
| Others (legacy Summarize, Generate, etc.) | 5 calls / minute |
Sending large volumes of requests in a short time may hit these limits, so caution is needed especially for batch processing.
In principle, Trial key can access all models and API endpoints that Cohere provides, same as Production key. There are no functional restrictions, allowing you to freely test features within the usage limit constraints mentioned above.
Cohere’s Trial key is an extremely valuable resource for developers, allowing you to try the API for free up to 1,000 calls per month. While there are constraints like rate limits, sufficient quota is provided to evaluate Cohere’s powerful Chat, Embed, and Rerank features.
