Instruction Following RL 66K

Dataset overview

instruction-following-rl-66k is an English training dataset for instruction-following reinforcement learning (RL/RLVR), containing 66,418 examples. It is derived primarily from AllenAI's IF_multi_constraints_upto5, whose instructions contain up to five verifiable constraints drawn from IFEval and IFBench-Train.

Each record is first validated for its JSON, prompt, and metadata structure. A predefined instruction-ID-to-constraint-checker mapping is then used to verify that every instruction ID has a corresponding checker and that the kwargs, checker-generated natural-language constraint description, and prompt are mutually consistent. The processing subsequently removes known mismatches between prompt descriptions and checker behavior, invalid copy-span boundaries, deterministic cross-constraint conflicts, and unstable targets that would require randomized default values to repair. Finally, records are deduplicated using the SHA-256 hash of the normalized prompt.

Data format

Each line is a JSON object with the following fields:

• prompt: A list containing a single user message in the form [{"role": "user", "content": ...}].
• label: An empty-string placeholder. Compliance is determined from the verifiable constraints stored in metadata; no supervised reference answer is provided.
• metadata.instruction_id_list: The list of instruction/checker IDs to validate.
• metadata.instruction_kwargs: A list of parameter dictionaries aligned one-to-one with instruction_id_list; checkers without parameters may use null.
• metadata.num_tokens: A precomputed token count. The tokenizer used to produce this value is not recorded in the released file.
• metadata.data_type: if for every example.

Illustrative example:

{
  "prompt": [
    {
      "role": "user",
      "content": "<task followed by one to five verifiable constraints>"
    }
  ],
  "label": "",
  "metadata": {
    "instruction_id_list": ["<checker-id-1>", "<checker-id-2>"],
    "instruction_kwargs": [{"<arg>": "<value>"}, null],
    "num_tokens": 128,
    "data_type": "if"
  }
}

Data processing

The dataset undergoes strict semantic validation and prompt-level deduplication:

1. Validate the structure and required non-empty values of the JSON record, prompt, metadata, instruction IDs, and kwargs.
2. Verify that every instruction ID maps to a defined constraint checker.
3. Confirm that each checker accepts the supplied kwargs keys and values as-is, rejecting invalid parameters that depend on randomized defaults for repair.
4. Reconstruct the natural-language constraint description and verify that it agrees with both the prompt text and kwargs.
5. Remove known mismatches between prompt descriptions and checker behavior, invalid copy-span boundaries, and deterministic cross-constraint conflicts.
6. Deduplicate records by the SHA-256 hash of the normalized prompt and write the output atomically through a temporary file.
