Question 1

How much does AI21 Labs cost?

Accepted Answer

AI21 Labs's published pricing changes often enough that a static number goes stale fast. Use the calculator above to plug in your own monthly usage and see the current verified rate applied — VendorSpies re-checks AI21 Labs's pricing page on a regular sweep, so the figure reflects the latest captured snapshot, not a cached guess.

What are AI21 Labs's API rate limits?

Rate limits vary by account tier and model, and vendors adjust them without much notice. Paid VendorSpies accounts can see every tier we've captured for AI21 Labs in the history view above, including when a limit last changed — add a free watch on this vendor to get notified the next time it moves.

Question 3

Has AI21 Labs increased its prices recently?

Accepted Answer

Check the price history and forecast panel above for the latest detected change on AI21 Labs. VendorSpies diffs the vendor's published pricing on every sweep, so a real increase, decrease, or new tier shows up here as soon as it's verified — rather than relying on a vendor's own changelog, which providers don't always update promptly.

Question 4

What happens if I hit a 429 rate-limit error on AI21 Labs?

Accepted Answer

A 429 means you've exceeded the current rate limit for your account tier on AI21 Labs — usually resolved by backing off and retrying with exponential backoff, batching requests, or requesting a tier increase from the vendor. If AI21 Labs has recently tightened its limits, that's exactly the kind of change VendorSpies tracks and alerts on.

Question 5

How do I get alerted when AI21 Labs changes its pricing or rate limits?

Accepted Answer

Add AI21 Labs to a free VendorSpies watch and we'll email you the moment a verified change is detected — no need to keep checking the vendor's page yourself. Paid plans add Slack and Microsoft Teams delivery alongside email, so the whole team sees it at once.
