Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
AI21 Labs
- The free allowance is $10 of credit lasting 7 days rather than an ongoing free tier
- Jamba Large is $2 per million input tokens and $8 per million output, so output-heavy work costs four times as much as input
- Volume discounts, private cloud hosting and higher rate limits require a custom plan
- Standard rate limits are not published
Cohere
- API-only service with no self-hosted options for most users
- Trial tier severely limited at 1,000 calls per month
- Smaller context window compared to some competing APIs
- Less emphasis on safety and alignment compared to competing APIs

Answered from the vendors’ own pages
Cohere: Does Cohere offer a free tier?
Yes. Cohere provides Trial API keys that allow 1,000 free API calls per month across all models and endpoints. Trial keys are rate-limited to 20 requests per minute for Chat endpoints and 5-10 requests per minute for other endpoints, and cannot be used for production or commercial purposes.
SourceCohere: What is the cost structure for production use?
Cohere uses pay-as-you-go pricing based on tokens consumed. Costs vary by model: Command costs from 0.15 to 2.50 USD per 1M input tokens, with output tokens priced higher. Embed models cost 0.10 USD per 1M input tokens. Production keys have monthly billing with invoices at month-end or when charges reach 250 USD.
SourceCohere: Can I self-host Cohere models?
No. Cohere operates as an API-only platform. However, enterprise customers can arrange dedicated or managed deployments through the Model Vault platform starting at 4.00 USD per hour with custom pricing for dedicated instances.
SourceCohere: What are the main differences between Cohere and Claude API?
Cohere excels in cost-effective NLP applications and retrieval-augmented generation (RAG) capabilities. Claude API emphasizes reasoning and safety with Constitutional AI training. Cohere's Command R+ offers similar performance to GPT-4 at 40-50 percent lower cost, while Claude focuses on factual accuracy and transparency.
