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

Tabnine

No published free tier as of the current pricing page, unlike several competitors that offer free individual plans
Pricing is higher than many consumer-focused AI coding assistants, targeting enterprise budgets
Now owned by Tricentis, a testing-focused company, introducing uncertainty about long-term product direction outside quality engineering use cases
LLM usage costs apply separately when using Tabnine-provided model access, on top of the per-seat license fee
