Get paid to train AI: expert contract work and what it pays

Yes, you can get paid to train AI if you are a credentialed professional. Platforms recruit doctors, lawyers, finance specialists, scientists and senior engineers to grade, correct and stress-test model answers. Pay claims run from about $31 an hour on average to $75 to $200 for top specialties, but those are the platforms' own numbers, and the work is irregular.

What "training AI" means for an expert

You are not writing the model's code. You are the human standard its answers get measured against.

The usual tasks are short and repeatable. A platform shows you two model answers to a question in your field and asks which is better and why. Or it gives you one answer and asks you to fix the reasoning, rewrite the conclusion and flag anything dangerous. Sometimes you write the reference answer the model should learn to imitate. Sometimes you write the test questions future models are graded on. Sometimes your job is to attack the model: find the prompt that makes a legal assistant give negligent advice and document how it failed.

A radiologist might read fifty model-written reports and mark each as safe, flawed or wrong, with two lines on the miss. A litigator might get a memo full of confident citations and be asked to check every one, since invented citations are a known failure of these systems.

The early version of this industry was cheap labeling, such as tagging images. That work still exists and pays little. The newer layer wants someone who can tell whether an answer would survive a professional review.

Why the labs spend money on it

The easy training data is used up. A model can learn grammar and basic facts from the open web for free. It cannot get a board-certified read on a differential diagnosis for free. That judgment is scarce, so it is paid for.

The money in this market is large. According to Fortune, Meta put $14.3 billion into Scale AI in June 2025 for a 49% stake, valuing the data company at $29 billion. Inc. reports that Surge AI, which supplies expert feedback to AI labs, made well over $1 billion in 2024 revenue without venture funding. And TechCrunch says Mercor, which matches experts to labs, raised money at a $10 billion valuation in October 2025 and pays more than $1.5 million a day to contractors.

These are company results, not your income. They show that buyers exist and are paying, which is the first condition for a second income line.

What it pays, and the caveat that matters

Mercor's own rates page puts the average AI trainer at about $31 an hour, in a range of roughly $12 to $200 or more. It says top expert specialties such as medicine, law, finance and advanced science sit around $75 to $200 an hour. TechCrunch reports that across Mercor's more than 30,000 experts, the average is over $85 an hour.

Now the caveat. These figures come from the platform or from reports about it. No independent body audits them. The top end is real for some people on some projects, but it is not a salary and it is not promised.

Your pay depends on your specialty, your country, how many hours a project offers and whether you pass the assessments that gate better work. Plenty of qualified people sign up and then wait weeks for a first task.

Treat the headline rate as the ceiling for a narrow slice of work. A fair description is a variable side income that can be good per hour while it flows, and nothing when it stops. Keep your main practice running.

Who gets in

The better tiers are gated by credentials you can prove. Platforms recruit most in medicine, law, finance, mathematics, the sciences and senior software engineering. TechCrunch says Mercor's roster leans on scientists, doctors and lawyers.

Expect to show a license, a degree, a publication record or a verifiable work history, usually with several years of practice behind it.

Adjacent skills count if the work is specific enough. A pharmacist can grade drug-interaction answers. An accountant can check tax math. A security researcher can probe a model for unsafe code. A court interpreter can catch a mistranslation that changes a ruling.

The overlap with automation resistance is not an accident. The skills that are hard to automate (high stakes, real ambiguity, a correct answer a non-expert cannot fake) are the skills a trainer needs.

How to apply

The process looks more like a job application than a gig sign-up. Create a profile on a platform that recruits experts, verify your credentials and take the assessment, which calibrates your judgment against the platform's standard. Pass and you are matched to projects in your field.

A few things help:

• Describe your actual sub-specialty. "Tax law for cross-border contractors" beats "finance."
• Be accurate about credentials. They are checked, and a failed check can close the account.
• Treat the assessment like an exam. The rate you are offered later often tracks how you did.
• Expect uneven work. Many people join two or three platforms to smooth the gaps.

Contract, tax and IP

This is contractor work, and the paperwork comes with it.

You are almost always an independent contractor, not an employee. The IRS describes the line as control: you are independent when the payer controls the result but not how you do the work, and the pay is reported on Form 1099-NEC. If you work from another country, the tax form and rules differ, so ask your accountant.

In the US, being independent means self-employment tax. The IRS says in Topic 554 that the rate is 15.3%, made up of 12.4% for Social Security and 2.9% for Medicare, and that you generally owe it once net self-employment earnings reach $400. Nothing is withheld, so set money aside. Our guide to estimated quarterly taxes explains how.

On intellectual property, assume you will not own what you produce. Reference answers, corrections and test questions are normally assigned to the platform or its client, and you will sign a confidentiality agreement limiting what you can say about projects. Read those terms before you start, particularly if your main job has its own confidentiality rules.

There are no benefits and no guaranteed hours. Check all of this with your accountant or lawyer before you rely on the income.

When a platform contact becomes your own client

Here is the part worth planning for. A researcher at a lab likes your domain memos and asks you to consult directly. A startup you met on a project wants ongoing review work. The platform that handled the contract, the tracking and the payout drops out, and you are running a practice again.

That is a normal path for people with real expertise. Other income lines grow the same way, as our post on referral and affiliate income shows. What changes is that you now need the whole client cycle yourself: a proper quote, a contract, a deposit, an invoice and a safe place to deliver written work.

How Delivvo handles the direct client work

Delivvo is for the moment a platform contact turns into a client of your own. It does not place you on AI projects, and it is not a marketplace. It runs the business side of the direct work.

The flow for a consultant looks like this:

1. The new client fills in your inquiry form, which lands on the lead board with their answers attached.
2. You send a quote from packages and add-ons, for example a fixed review fee or a monthly retainer.
3. On Pro, the one-page close lets the client choose, sign and pay the deposit on one link. The contract, invoice and payment schedule are created from it.
4. You deliver memos and reports through the client portal. Because the work is confidential, the portal opens with a one-time code instead of a shared inbox, and files sit behind short signed links.
5. The client approves the deliverable, and the approval is recorded with a name and time.
6. They pay through your own gateway, and Delivvo takes 0%.

For confidential work, two details matter. Contract signing records include a SHA-256 hash, the IP address and device, with an archived PDF. And every invoice and contract carries a verification code that a client's finance team can check.

Recurring invoices cover a monthly retainer, and payment schedules of up to 12 payments cover larger projects. See the contracts and e-signatures page for the signing flow. Whether to do this work at all is your call, and your tax position is something to settle with your accountant.
