Ground-truth data for AI labs

We build the hard problems that test frontier AI.

Top AI labs use our tasks to train and test their models. Every task is checked by machine, so a passing score is always real.

The easy problems are already solved. The next gains come from problems that are genuinely hard, and impossible to fake.

The best models already pass the public tests. To get better, they need harder problems with answers that can be checked, not guessed.

Most data on the market is sloppy. It is vague, random, or easy to cheat, and it teaches a model the wrong thing. We build the opposite.

Four kinds of hard, checkable work.

Every tile is real product, not a description. This is what we build for labs.

Coding & agent benchmarks

Coding tests

Real software problems an AI agent solves step by step, graded by hidden tests that fail on the broken code and pass only on the fix.

- def resolve(node):
+ def resolve(node, source=None):
+     return dispatch(node.value, source)
# pytest -q  12/12 passed
RL environments

Practice worlds

A sealed world with a checker that only passes on a real win.

RLVR

Math and reasoning

Problems that ship with a correct answer and an exact checker.

Agentic evals

Open-ended analyst tasks

Messy, real-world data questions where the agent has to work out what actually matters, with plausible traps that look right but are not.

# underspecified prompt + 4 messy sources
join: stripe  ↔  postgres  ↔  events
signal hidden in 2-table overlap
# red herrings present, skepticism scored

What we have shipped

The work, shown as the process.

Seven kinds of data work we have delivered. Each one shown as how it is built, with no client named.

Coding & agent benchmarks

An agent gets a real codebase and a hidden test suite. The tests fail on the broken code and pass only on the correct fix, so a green run is a real result, not a guess.

How a task
gets made.

Every task follows the same path, from a shared goal to a checked delivery.

01

Brief

We agree the goal, the scope, and what a good answer looks like.

02

Build

We build the task on real code or data and write the checker.

03

Verify

It clears our checks: clean build, repeatable, backed by a real answer.

04

Calibrate

We test it against strong agents and tune it to the right difficulty.

05

Deliver

You get the task in your format, with the solution and the checker.

How we check

Most things do not pass. Ours do.

Every task runs through a fixed set of checks. Only the ones that hold up reach you.

checked, then passed

Hard on purpose.

A task is only useful in a narrow range. It has to be hard enough that most agents fail, and just within reach for the best.

We test each task against strong agents and keep the ones that land in that range. Too easy or too hard, and we fix it or drop it.

agent pass rate, per task too hard in range too easy

Each dot is a task. We keep the ones in range, and fix or drop the rest.

Why labs come to us

We clear the hardest bars

Our tasks ship inside the public benchmarks labs use, and we have passed the top review tiers of leading data platforms.

No lab owns us

Your prompts and data stay yours, and stay private. We work for you alone.

We do one thing

Only the hardest checkable tasks. That focus is why every task holds up.

How we work with you

  • You own the work in full
  • NDA first, always
  • Sealed, network-isolated builds
Trust & security

We deliver in the formats your team already uses. Plug it straight into your training and eval pipelines.

Founder & Lead

Akash is an engineer and designer. He builds and reviews hard tasks across coding, agent environments, math sets, and open-ended analyst work. His tasks ship inside public AI benchmarks and have passed the top review tiers of leading data platforms. He also designed Topdeta's brand and built this site.

A small, vetted team of reviewers checks every task before it ships, with calibration and failure analysis on each one.
