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
Deepgram
- Pricing is entirely usage-based, so total cost can be harder to predict than flat subscription tools.
- The Growth plan requires a minimum $4K/year commitment to unlock discounted rates.
- Enterprise features and custom SLAs require a direct sales conversation rather than self-serve signup.
- Some promotional per-minute rates are time-limited, meaning long-term pricing may differ from current promotional rates.
