IMPORTANT NOTE
This data is part of the progress. Current translation progress: 24.85% (2024-09-18 01:32 KST)
I'm taking a short break due to personal reasons. I'll be back in a month.
TODO-LIST
Finish translation
Translation
I used gemini-1.5-pro-exp-0827. The prompt used for translation will be disclosed at the end.

Dataset Card for Evaluation run of AI-MO/NuminaMath-7B-TIR
Dataset automatically created during the evaluation run of model AI-MO/NuminaMath-7B-TIR
The dataset is composed of 38 configuration(s), each one corresponding to one of the evaluated task.
The dataset has been created from 1 run(s). Each run can be found as a specific split in each configuration, the split being named using the timestamp of the run.The "train" split is always pointing to the latest results.

Lean per-turn GPT-OSS training export derived from
brian-rollouts-311-full-v2.
Contents:
rollouts.training_turns.jsonl: one row per assistant call with full prompt token IDs and completion token IDs
manifest.json: export metadata and row counts
Semantics:
prompt_token_ids are the full context shown to the model for that assistant call.
completion_token_ids are the tokens generated by the model on that call.
prompt_token_ids include system… See the full description on the dataset page: https://huggingface.co/datasets/aimosprite/brian-rollouts-311-training-turns.ai-model-accent-corpus
AI Model Accent Corpus
A paired corpus for studying the prose "accent" of large language models: 5 models × the same 102 open-ended prompts = 510 plain-prose passages, generated June 2026 at a fixed decoding temperature, constrained to plain paragraphs (no lists or headings) so the data isolates prose style rather than formatting choices.
Models: OpenAI GPT-4o, GPT-4o-mini, GPT-3.5-turbo; Anthropic Claude Sonnet 4.5, Claude Haiku 4.5.

MOH-8 Fake Rollouts
480 math competition problems, each with 8 candidate solution rollouts from OSS 120B.
A controlled number of rollouts per problem are correct — use this to train/test a
verifier model that must identify which solutions are right.
Source
Problems and rollouts sampled from aimosprite/training-data-oss120b (the oss128-fixed-FINAL.jsonl file).
Only polymath-source problems in the 2/8–4/8 pass rate range (32–64 correct out of 128 attempts).
