AI21’s official pricing page, checked on 7 October 2026, advertises a free trial with US$10 in usage credit for seven days and no credit card required. This guide explains how to prepare an evaluation and inspect the account conditions before spending that balance. It is based on public documents, not a completed account signup or a benchmark of AI21 models. Publisher: SmartDealIndex. Independent editorial review is pending. Links are ordinary official URLs.

What the offer provides

The official pricing page is the starting point for the current offer. The credit is a temporary balance for eligible platform usage. A dollar amount does not translate into a universal number of tokens, prompts or completed tasks: the applicable model and charging unit determine consumption. Check the model pricing shown in your account and compare it with the public pricing before estimating capacity.

Treat the seven days as a short evaluation window. The public record does not establish a recurring monthly allowance, an automatic renewal of free credit, or cash that can be withdrawn. Pay-as-you-go and custom commercial plans shown alongside the trial are separate arrangements. A trial can help you decide whether a paid integration makes sense, but it does not establish that production usage will remain free.

The exact activation event, account expiry timestamp, supported countries and model-specific trial restrictions have not been fully verified. Inspect these details before running requests. Record both the date and timezone displayed by the account; a calendar reminder based on an assumed local midnight can be misleading.

Prepare the test before signing up

Choose one real task you already understand. Examples include producing a draft summary of a public document or classifying a small set of synthetic support messages. Define what a useful answer must contain, which mistakes would make it unusable, and whether a human must check each result. Avoid submitting confidential business data simply because a trial is free; review the provider’s terms and your own data permissions first.

Prepare a compact dataset with ordinary examples and difficult cases. For a summarization experiment, include a short text, a longer text with repeated information, and a text where an important limitation appears near the end. For classification, include ambiguous messages and a category that should be rejected. These are suggested evaluation designs, not claims about measured provider performance.

Decide how you will measure success. A small spreadsheet can record the input identifier, expected characteristics, selected model, prompt version, observed result, usage cost and human correction time. This lets you compare useful completed work instead of judging one impressive demonstration. Keep the initial dataset small enough to inspect manually.

Follow the official signup route

1. Open the official pricing page and reread the trial amount and duration. Offers can change after this source check.
2. Follow its free-start link to AI21 Studio signup. The linked signup route returned an access restriction during our unauthenticated check, so the form and account screens were not inspected. That response does not prove the program is closed.
3. Use your genuine account details and read the presented terms. Do not create duplicate accounts to repeat a new-account promotion.
4. After access is granted, check whether the account actually shows trial credit, its expiry and the models eligible to use it. Save the account confirmation for your own records.
5. Consult the official documentation for the current integration method. Use the labels and authentication procedure shown there, rather than assuming that a particular dashboard menu exists.
6. Run a minimal request, inspect the result and its recorded consumption, and only then expand the experiment.

No account was created for this guide. Account acceptance, an individual country’s eligibility and the exact post-signup flow remain unverified. If the displayed amount differs from this article, pause and use the provider’s current account terms as the basis for your decision.

Spend the balance deliberately

Divide the experiment into a baseline and one controlled change. First use a simple prompt on a few examples. Then change one instruction or model choice while keeping the inputs stable. Changing everything at once makes it difficult to understand why the output improved or deteriorated.

Keep input length and requested output length proportionate to the task. Repeatedly sending a long source document may consume more of the balance than necessary. Before a batch, estimate its cost using the charging units for the selected model; after a small sample, compare that estimate with the observed usage. Stop and investigate unexplained differences before continuing.

Add a maximum run size to any script. A loop that retries without limits can spend a short trial quickly, even when the final output is poor. Keep credentials out of shared documents and public repositories. Store examples without unnecessary personal information, and make the evaluation reproducible through prompt versions and input identifiers.

Reserve time to review failures before the window ends. The useful outcome is a decision: continue with a paid plan, revise the approach, or stop. A high volume of requests is not itself evidence that the integration saves time or produces acceptable results.

Decide what happens after the trial

Before connecting production traffic, inspect the payment and usage controls available in your account. This research did not verify automatic billing, automatic plan transitions, spending caps or alerts. Do not infer any of those behaviors from the phrase “no credit card required.” Read the account’s current billing terms and verify how to stop requests.

Estimate a representative paid month from the measured sample, including failed requests or repeated work where applicable under the actual charging rules. Document the model and pricing date used in the estimate. A small trial is a basis for an initial calculation, not a service-level commitment or proof that every future input will behave similarly.

Record the conclusion and remove unused credentials or integrations according to your team’s process. Keep the credit expiry separate from any later paid balance.
