R-Zero Qwen3-8B-Base — global step 96

This repository contains the user's R-Zero experiment checkpoint at cumulative global step 96 (round 3, round-local step 32). It is an experiment artifact, not an official release by the Qwen or R-Zero authors.

The four BF16 safetensors shards and tokenizer/configuration files are copied byte-for-byte from the existing Hugging Face-format checkpoint. The model was not loaded, merged again, or re-exported for this upload. The index contains 399 tensors and 8,190,735,360 parameters. Per-file SHA256 checksums are recorded in checkpoint_manifest.json .

The upstream base is Qwen/Qwen3-8B-Base , whose published model card identifies the Apache 2.0 license. The standard license text is included in LICENSE .

Evaluation scope

This checkpoint was selected by the recorded unweighted mean over seven prior benchmarks, not by Omni-MATH-2 scores. This upload makes no claim about its Omni-MATH-2 accuracy or its strongest/weakest domain-by-problem-type cell.

For the separate omni_math2_standalone evaluation package, use a pinned commit revision when downloading and a separate run named rzero_96 . Do not use the RQ step-256 wrapper with this model: the wrapper targets rq_256 .

Keep decoding and grading settings unchanged when comparing checkpoints. Generated answers may be incorrect; neither model outputs nor benchmark reference answers are guaranteed correct.
