Grading

Completions are graded by the platform, never by the trainer: the trainer submits {taskId, completion} batches and the verdicts come back as task events.

Grader	Kind	What it checks
score-answer	Program	The family’s score_answer; only a full score is Correct, the score is the reward

Sample task

One line of nodus-env tasks --split test --seed 0; tasks never carry answers.

{
  "metadata": {
    "family": "basic_arithmetic"
  },
  "prompt": "Calculate -3 - 8 / ( -8 + 1 + 8 ).\n\nReply with the final answer only. Do not restate the question, do not show working, and do not add any words, labels or punctuation around it.",
  "taskId": "reasoning-gym-v1-0-1:test:0:0"
}

Examples

Each example is a TrainingJob template. A baseline is shown only where the example was measured by running it.

From the repository root, preview the generated manifest using your configured API context:

$ nodus create -f examples/training/catalog/reasoning-gym-v1-0-1/chain-sum.yaml --dry-run=server -o estimate

Or preview the catalog example with the Python SDK:

import nodus

client = nodus.Client()
nodus.api.set_default_client(client)
job = nodus.TrainingJob.from_example("nodus/reasoning-gym-v1-0-1:chain-sum")
print(job.preview().estimate)
client.close()
