RL environment budget worksheet

Enter how many tasks you need, how they are graded and which rights you want. The worksheet multiplies the only published per-task range (Epoch AI's) by your count and lists the questions that decide where a real quote lands.

How much should we budget for an RL environment?

How is a task graded?
Rights

Planning basis

$100,000 to $1,000,000

500 tasks at $200 to $2,000 each.

Basis: Epoch AI's interview-based range, Epoch AI, 12 Jan 2026. Not a quote or an offer; actual prices vary widely and can sit far outside this range.

Ask the vendor

  1. How many tasks can reuse one sandbox image, and what does a new image add?
  2. How are graders tested against wrong solutions before delivery?
  3. How do you find and remove near-duplicate tasks?
  4. Which other buyers can license the same tasks, and is that list disclosed?
  5. Do we receive the environment code and tasks, or hosted access only?
  6. Who owns the trajectories our training runs produce?
  7. What does a paid pilot of a small task set cost, and what would make you reprice the full order?

What should we ask every RL environment vendor?

The worksheet shows the questions for your choices. Here is the full set.

For any project

  • Do we receive the environment code and tasks, or hosted access only?
  • Who owns the trajectories our training runs produce?
  • What does a paid pilot of a small task set cost, and what would make you reprice the full order?

Automatically checked tasks

  • How many tasks can reuse one sandbox image, and what does a new image add?
  • How are graders tested against wrong solutions before delivery?
  • How do you find and remove near-duplicate tasks?

Multi-step tasks

  • How many steps does a typical task take, and how is partial credit scored?
  • Which tools does the agent get, and are they documented per task?
  • What share of tasks did your own reviewers fail to solve, and what happened to them?

Rubric or expert-graded tasks

  • Who writes the rubrics, and what is their background in the domain?
  • Is grading done by a model judge, a person, or both, and how do you check agreement?
  • What does a re-grade cost if we change the rubric later?

Rights

  • Which other buyers can license the same tasks, and is that list disclosed?
  • How long does exclusivity last, and does it cover the graders and the sandbox code too?
  • What is the price for each option, shared and exclusive, on the same task set?

Questions about the worksheet

Where does the worksheet's range come from?
From Epoch AI's FAQ on RL environments (12 Jan 2026): $200 to $2,000 per task in most cases, and 4 to 5 times that for exclusive deals. Both are interview estimates.
Why does complexity not change the number?
No source publishes cost by complexity, so the worksheet does not guess. Complexity changes the questions you should ask instead, because it changes what drives the quote.
Is the result a quote?
No. It is a planning bracket built on published estimates. Vendors quote per project, and actual prices can land well outside it.
Does the result include training compute?
No. It covers building tasks and graders only. Running training is a separate cost.
