Aya Expanse 32B on Cohere
Cohere Free API tier
The catch: Only 1,000 calls a month across all endpoints, trial keys may not be used for production or commercial work, and trial data falls under the general Terms of Use, which let Cohere use it to improve its services.

Before you ship on it
- Only 1,000 calls a month across all endpoints, trial keys may not be used for production or commercial work, and trial data falls under the general Terms of Use, which let Cohere use it to improve its services.
- Prompts on the free tier may be used to train models. Keep customer data off it.
- cohere.com/pricing FAQ: 'API calls made from a Trial API key are free. However, trial keys are rate limited and are not permitted to be used for production or commercial purposes.' Production use needs a paid production…
- Free tiers are shared capacity: treat the limits as a ceiling, not a promise, and keep a paid fallback.
